Car Radio Antenna

When you get into a car with no exposed antenna, but you can still listen to FM/AM clearly, it is the technical transition from "rod-exposed" to "invisible integration" of the Car Antenna. Today's Car Radio Antenna has already got rid of the traditional metal pole modeling, and turned into a miniaturized module embedded in the instrument panel or the roof interlayer—for example, BMW iX's "glass antenna" technology that integrates the antenna in the windshield interlayer, or Mercedes-Benz S-class 5mm ultra-thin PCB Antenna matrix embedded in the roof lining, which enhances the signal reflection through the metal frame of the car body, and only a palm-sized module can cover the full-band radio demand, so that the interior design can completely get rid of the visual interference of the "antenna pole". This hidden antenna design is infiltrating into the global automobile market with Europe as the center: in 2024, 75% of the newly listed models in Europe have adopted the dual antenna integration scheme of instrument panel and ceiling, such as Porsche Panamera achieving both signal and light weight through the built-in antenna on the carbon fiber roof; The Asian market is also catching up quickly. Toyota Crown 2022 is equipped with dashboard antenna for the first time, and BYD Han EV's "Shark Fin" antenna integrates six functions such as radio, GPS and 5G communication. More importantly, this kind of antenna is no longer limited to a single radio function, but is deeply integrated with the car phone and navigation system-Volkswagen ID series antenna Modules can even handle FM/AM, car networking calls, real-time road conditions and other multi-band signals at the same time, making "one antenna meets all needs" a reality. With the rapid increase in the number of smart devices in vehicles, the integration trend of FM/AM radio antennas will be further accelerated in the future. Industry forecast shows that in 2025, the number of antenna modules of a single car will increase from the current 2-3 to 5-7, and the application of new materials such as graphene conductive ink and flexible printed antenna (FPC) will reduce the antenna weight by 40%, while supporting curved surface installation (such as curved dashboard); AI intelligent tuning technology can optimize signals in real time through machine learning, and automatically enhance reception stability in scenes such as tunnels and mountains. By then, the car antenna will no longer be just a "signal receiver", but will evolve into a "car communication hub" integrating radio, navigation and road coordination, and continuously upgrade the driving experience in an invisible manner. 1. What is the market popularity of hidden antennas? Leading in Europe: In 2024, 75% of new models in Europe will adopt hidden antennas, and all high-end models of BMW and Audi will come standard with integrated antenna modules; Follow-up in Asia: Toyota's 2022 Crown is equipped with dashboard antenna for the first time, and China brands such as BYD Han EV's "Shark Fin" antenna integrate six functions. In 2024, the penetration rate of domestic vehicles with more than 150,000 vehicles reached 62%; Trend forecast: With the increasing demand of vehicle networking, the number of antenna modules in a single vehicle will increase from 2-3 to 5-7 in 2025, supporting multi-band integration. 2. How will the car antenna develop in the future? Multi-band integration: In 2025, the antenna will integrate FM/AM, 5G, C-V2X and other frequency bands. For example, Qualcomm AeroAntenna technology supports 12 frequency bands to work at the same time; Application of new materials: the weight of graphene conductive ink antenna is reduced by 50%, and it can be printed on curved glass (such as BMW i7 panoramic sunroof antenna); AI intelligent tuning: Optimize signal parameters in real time through machine learning, and automatically switch frequency bands in underground garages and other scenes to improve reception efficiency. 3. Where are the hidden antennas mainly installed in the car? How to work? Embedded instrument panel: spiral PCB antenna is implanted in the center console, and the metal instrument panel frame is used as the reflecting surface. The typical case is the instrument Panel Antenna module of Toyota Crown, with a thickness of only 8 mm; Ceiling integration: the antenna, GPS and Wi-Fi modules are integrated into an ultra-thin board and embedded in the roof lining, such as the roof antenna matrix of Tesla Model 3, which can simultaneously process FM/AM and car networking signals; Working principle: The resonant circuit is formed by the metal parts of the car body (such as the roof and the door), and the signal receiving area is enlarged, which is equivalent to the "invisible antenna array".

When I was in go on road trip, someone was anxious to pull the roof antenna to the longest, thinking that more radio stations could be found in this way, but the noise continued. Is the longer the Car Antenna, the stronger the radio signal? The answer is not so. The signal receiving effect of automobile Car Antenna is not simply determined by physical length. Just like an instrument can only play a beautiful melody in a specific range, the ability of an antenna to receive signals is closely related to its working frequency. Radio waves in different frequency bands correspond to different wavelengths. Only when the antenna length and wavelength form an appropriate ratio can efficient signal Transmission be realized. At the same time, the vehicle environment also affects the signal quality in secret: shuttling through the city streets with high-rise buildings or driving in tunnels, the surrounding obstacles will reflect and absorb radio waves, and even if the antenna is longer, it is difficult to break through the "signal dilemma"; In addition, the metal material of the car body will form a shielding layer, which also requires the antenna design to adapt to it. Nowadays, with the development of technology, car antennas have long since got rid of the thinking of "winning by strength". Engineers use advanced electromagnetic simulation technology to design and optimize the antenna precisely, so that the short shark fin antenna can not only take FM/AM radio reception into account, but also integrate GPS, 4G or even 5G signal reception functions to achieve stronger and more stable signal reception effect in a limited space. In order to solve the problem of unstable radio signal, car radios are often equipped with retractable antennas. The common FM AM Antenna is mostly installed on the roof, where the vision is wide, there are few obstacles and the signal attenuation is low, which can create good conditions for signal reception. This kind of antenna is connected to the car body through a rotating hinge, so the owner can freely adjust the tilt angle according to the actual needs and flexibly adapt to different driving scenes. In design, Car Radio Antenna with total length less than 200mm are more common. Although they are small in size, they can take into account the signal reception in AM and FM bands, which can not only ensure the radio to stably play news and music, but also provide communication support for car phones, realize diversified functions with exquisite structures, and play an efficient role in a limited space. Why is the car roof antenna stretched to the longest, or is there a lot of noise and no more radio stations? A: The signal receiving effect of the car antenna is not determined by a single physical length. The ability of the antenna to receive signals is closely related to the working frequency. Only when the antenna length and the wavelength of the corresponding radio wave form a proper ratio can the signal be transmitted efficiently. Simply stretching the antenna, if the frequency is not matched, can not enhance the signal, and may also introduce more noise. Q: How to improve the signal reception of car antenna when driving in the city? A: Because there are many obstacles in the urban environment, radio waves are easily disturbed. Try to select an open road section to receive signals; You can also choose an antenna designed for complex environment, or optimize the installation position of the vehicle antenna to reduce the influence of the metal shielding layer of the car body to improve signal reception. Q: Do all types of car antennas follow the principle of the ratio of antenna length to wavelength? A: Yes, no matter what type of car antenna, its signal reception essentially follows the principle that the antenna length and wavelength need to be adapted. Different types of antennas are only different in design, structure and applicable scenes, but this basic condition must be met in order to achieve efficient signal transmission.

Automobile FM/AM antenna: the "receiving hub" of information and music during driving. When you drive through the city streets, or gallop on the open road, you can listen to real-time road conditions, news information and melodious music by turning on the radio. Behind this convenience, the FM/AM antenna of the car radio is indispensable.it is not only a unique symbolic part of the car's appearance, adding a touch of practical beauty to the vehicle, but also the core hardware that accurately realizes the reception and Transmission of broadcast signals, ensuring that every piece of information can be smoothly delivered to your ears. There are many kinds of Car Antenna in automobiles, including high-gain automobile radio antenna, automobile TV Antenna and automobile GPS Antenna. These car-mounted ones serve specific in-vehicle needs, with functions varying by type. It is usually installed in conspicuous and open positions such as the roof and front of the car, and this design has strict scientific considerations. Radio waves emitted by radio stations propagate in a straight line or approximate straight line. Putting the antenna on the roof and other heights can reduce the obstruction of obstacles such as metal structures and buildings in the car body and capture the broadcast signals to the maximum extent. At the same time, the high installation position can make the antenna better receive electromagnetic waves from different directions, and improve the stability and comprehensiveness of signal reception.​ The working principle of FM AM Antenna is based on electromagnetic induction. When the high-frequency electromagnetic wave emitted by the radio station meets the antenna, it will generate induced current in the antenna conductor. After a series of processing such as amplification and demodulation, this weak current signal will be converted into a playable audio signal by the car radio. Whether it is high-fidelity music programs provided by FM frequency band (87.5-108MHz) or news information and traffic conditions spread by AM frequency band (526.5-1606.5kHz), it needs to be accurately captured and transmitted by FM AM Antenna to be clearly presented to drivers' ears.​ In actual driving, Car Radio Antenna and even devices like walkie talkie antenna (though not primarily for in-car entertainment) have their roles. For the former, it enables drivers to listen to traffic broadcasts, obtain information such as road congestion and accidents in advance and adjust the route in time; News broadcast allows drivers to keep abreast of current events on the road; Soothing music and interesting programs can effectively alleviate driving fatigue, making the long journey easy and enjoyable, and greatly improving the driving experience while ensuring driving safety. FAQ: 1.What are the main installation positions of FM/AM antennas and why?​ It is usually installed in open positions such as the roof and front of the car. This is because radio waves propagate in a straight line. A high installation position can reduce the obstruction of the car body and buildings, and better receive electromagnetic waves from all directions, improving signal stability.​ 2.Can FM/AM antennas receive both FM and AM signals?​ Yes. It can accurately capture and transmit signals of FM frequency band (87.5-108MHz) and AM frequency band (526.5-1606.5kHz), so that drivers can listen to corresponding programs.​ 3.Will bad weather affect the signal reception of FM/AM antennas?​ In general, light rain and snow have little impact, but severe weather such as thunderstorms may cause certain interference to radio waves, resulting in temporary signal instability, but it can usually return to normal after the weather improves.​ WELCOME TO CONTACT US!

You can choose according to the characteristics of the car and your personal needs.

If I want to receive radio station signals in my car, can I install only one Car Radio Antenna?If you want to listen to a radio station in your car, but your car does not have a radio installed, it will not be able to receive the radio signal. First, you need to install a radio in your car. After confirming that the radio can be used normally, you need to buy car radio Fm/AM antenna according to your car model. What you need to pay attention to when buying FM AM Car antenna Must buy FM AM Radio Antenna because FM AM Antenna for CAR is specially designed for receiving radio signals. Then choose the appropriate Car Radio Antenna appearance according to your car model. Connect Car Antenna to the radio and you can receive radio station signals.

As the key component of vehicle-mounted signal reception, the installation position of automobile Car Antenna is unique. The rear windshield, the side windshield and the front windshield may all become the "shelter" of the antenna. Among them, the design of printing metal wires on the front windshield skillfully transforms the glass into the antenna carrier. In the attack of FM/AM vehicle antenna performance optimization, engineers face the technical problems of limited Car Radio Antenna space and poor signal sensitivity, and make a breakthrough by combining front-end amplification and link optimization: by embedding a low-noise amplifier, the weak signal in the 30MHz-108MHz frequency band is directionally enhanced by more than 15dB. At the same time, the adaptive LC matching circuit is used to dynamically calibrate the Transmission impedance of AM(530-1710kHz) and FM(87.5-108MHz) bands, and the standing wave ratio is stably controlled within 1.3:1, which improves the signal transmission efficiency by over 30%, successfully overcomes the reception problems in weak signal scenes such as underground garages and mountainous areas, and makes the sound quality of car-mounted broadcasting clearer and smoother. The research and development of automobile FM AM Antenna is undergoing a revolutionary leap from "trial and error exploration" to "digital intelligence innovation". With the help of cutting-edge technologies such as electromagnetic simulation (MoM/FDTD algorithm) and finite element analysis (FEM), engineers can build a high-precision antenna model in virtual environment, accurately simulate key parameters such as radiation pattern and impedance matching characteristics, and shorten the traditional physical verification cycle by more than 60%. The deep integration of theoretical design methods not only improves the prediction accuracy of antenna gain, bandwidth and other core performance parameters to 92%, but also realizes the optimal solution of antenna structure and function through multi-objective optimization means such as genetic algorithm (GA) and particle swarm optimization (PSO), which promotes the iterative efficiency of product performance by nearly three times. As the core hub of in-vehicle communication, automobile FM and AM antenna supports multi-scene applications with strong compatibility: it is not only the "sound entrance" of AM/FM broadcasting, but also provides users with real-time news and music entertainment; More deeply integrated into the Intelligent Transportation System (VICS) to achieve millisecond reception of road information; At the same time, it supports FM multiplexing technology to transmit text information and audio content synchronously; In the field of vehicle multimedia, it also undertakes the functions of TV signal reception, Bluetooth telephone connection and so on, and even becomes a signal relay station for intelligent key, remote control and other equipment, and becomes a key infrastructure for intelligent upgrading of automobiles.

The core of car receiving radio signals is not a singleFM AM Antenna, but a complete receiving system with radio as the hub. As the core equipment, the built-in tuning circuit of the radio can accurately capture the radio wave with a specific frequency, and the demodulation module is responsible for analyzing the radio wave signal into an audio signal-this process is like a "signal translator", which is the key link for converting the radio wave into sound. If there is no radio, the car will lose its "brain" to process signals. Even if the antenna can capture radio waves, it cannot complete the conversion from electromagnetic waves to audio. In short, the radio is the "heart" of broadcast reception, and its professionally designed circuit system gives the car the ability to decode radio signals, while the antenna is only an auxiliary signal acquisition component, and their functions cannot be separated. The Car Radio Antenna is an indispensable "signal catcher" in the whole receiving system. The function of Walkie Talkie Antenna is to capture weak radio waves in the air, convert them into electrical signals and transmit them to the radio. Without an antenna, even if the radio is fully functional, it is difficult to obtain a signal with sufficient strength, resulting in poor radio reception or even inability to receive it. Radio and Car Antenna can be called the "golden partner" of car broadcast receiving system: the former is like a precise "signal processor", which completes core processing such as tuning and demodulation with built-in circuits; The latter is like a keen "signal catcher", responsible for collecting radio waves from the air. The two work together and are indispensable-without a radio, signals cannot be converted into sounds; Without antenna, signal acquisition will become passive water. Therefore, if you want to enjoy clear and smooth music and information while driving, the car must be equipped with a radio and an adaptive Shark Antenna. This combination of "double swords" is the basic guarantee for the stable operation of the car broadcast system.

Car Radio Antenna: the logic behind design differences ​ The difference in the shape, size and length of the Car Radio Antenna stems from the technical characteristics of signal reception and the requirements of environmental adaptation. The wavelength of radio waves in different frequency bands is different. For example, the wavelength of FM band (87-108MHz) is about 3.4-2.8 meters, and the antenna length needs to be in a specific proportion to the wavelength (such as a quarter wavelength), which directly determines the size. The shape affects the sensitivity, etc.: the rod antenna receives omni-directionally but is susceptible to metal interference, the spiral antenna shrinks to keep the signal, and the Patch Antenna enhances the signal by flat design.​ Vehicle positioning and usage scenarios determine the Car Antenna shape. Off-road vehicles often go to weak signal areas, and need high-gain long antennas to deal with complex terrain; Commuting in the city by family car, small size and short antenna or hidden money can be used; shark fin antenna for sports car is pneumatic and multifunctional, achieving the balance of "performance" and "aesthetics".​ Choosing FM AM Antenna should integrate the scene, vehicle characteristics and parameters. Choose high gain and adjustable length antenna for long-distance or remote areas; City compact cars are suitable for short models or hidden models. Attention should also be paid to gain, impedance matching and frequency coverage to ensure compatibility.​ Through precise matching, the performance of walkie talkie antenna can be fully exerted, and a clear and stable listening experience can be obtained. This is also the direction of continuous optimization of vehicle antenna design-adapting to requirements, balancing function and practicality.​ FAQ: 1.What determines the shape and size difference of car radio antenna?​ It is mainly determined by the technical characteristics of signal reception and the requirements of environmental adaptation. The wavelength of radio waves in different frequency bands is different, and the antenna length should be in a specific proportion (such as a quarter wavelength); The shape will affect the sensitivity, anti-interference and other performance, such as rod, spiral, patch and other designs are designed to adapt to different scenes.​ 2.Which antennas are suitable for off-road vehicles, family cars and sports cars?​ Off-road vehicles are suitable for high-gain long antennas to deal with weak signals in remote areas; Choose a small antenna or a hidden model for the family car to meet the needs of urban commuting; Shark fin antenna is commonly used in sports cars, which takes into account aerodynamics and multi-function signal reception.​ 3.What core factors should be paid attention to when purchasing FM/AM car antenna?​ The usage scenario (such as long distance/city), vehicle characteristics and technical parameters (gain, impedance matching, frequency coverage) should be considered comprehensively to ensure that the antenna is compatible with the radio circuit.

Car Radio Antenna Where should it be installed to better receive the signal? Generally speaking, the antenna should be installed in an unobstructed location to minimize the signal reduction caused by other obstacles. Therefore, the most suitable installation position for Car Antenna is the roof of the car, because the position of the roof is relatively open and unobstructed, which can minimize the impact of obstacles on radio signal reception, thus improving car radio Fm/AM antenna is the ability to receive signals from broadcast stations. In addition to the center position of the roof, you can also consider installing FM AM Car antenna on the rearview mirror or window glass. However, this requires you to choose the appropriate design and materials, and you also need to pay attention to the direction and position of the High gain car radio antenna to obtain the best signal reception.

How to choose Car Radio Antenna?To choose a Car Radio Antenna, you must first have a strong ability to receive radio signals to ensure that the received radio signals can provide clear and stable audio. At the same time, the car radio Fm/AM antenna must support multiple frequency bands at the same time: FM and AM, etc., to ensure that diverse content can be received. The FM AM Car antenna should be easy to install, require no additional settings, and can be used as soon as it is plugged in FM AM Antenna for CAR. It should be a universal style, or equipped with a variety of connectors to ensure that Car Antenna universal. If one Car Radio Antenna meets these conditions then you can choose it and it will ensure that you can enjoy a wide variety of radio content such as news, music, sports and entertainment.

Propagation characteristics of sky waves: FM/AM broadcast signals mainly propagate through spatial waves (direct waves+reflected waves). As the highest point of the whole vehicle (about 1.5-2 meters above the ground), the straight-line distance from the broadcast Transmission tower (usually 50-300 meters high) is shortened, and the blocking probability of ground obstacles (such as buildings and trees) is reduced. Minimization of car body shielding: if the Car Antenna is installed on the side or bottom of the car body, it is easy to be shielded by the metal structure of the car body (such as the door and chassis) during driving; The roof is in the position with the least "signal blind area", especially in the urban high-rise environment, the signal reception stability of the roof Car Radio Antenna is more than 30% higher than that of the bottom installation. Symmetrical layout of the roof: the center of the roof is close to the geometric symmetry axis of the vehicle, which is convenient for arranging omnidirectional FM AM Antenna (such as rod antennas and spiral antennas) to realize 360-degree uniform radiation/reception and avoid signal attenuation caused by vehicle steering. For example, the spiral polarized antenna can form a horizontal omni-directional coverage on the roof, but when installed on the side, it may produce a "lobe blind area" due to the metal reflection of the car body. Multi-path signal optimization: the height of the roof enables the antenna to receive direct waves and ground reflected waves at the same time, and the intensity is improved through signal synthesis. The measured data show that the multipath fading effect of the roof antenna is 15dB lower than that of the door installation, especially in the strong reflection scene such as tunnel exit, the signal recovery speed is 20% faster. Interference suppression of electronic equipment: The Engine, instrument panel, motor and other equipment in the car will produce broadband electromagnetic noise (mainly concentrated in the 0.1-100MHz frequency band, overlapping with FM/AM frequency band). The distance between the antenna on the roof and the electronic equipment in the car is ≥ 1.5m, and the interference intensity can be reduced to 1/10 (according to the electromagnetic radiation inverse square law) through spatial isolation. Shielding effect of metal car body: The antenna on the car roof is located above the metal car roof, and the car body itself can be used as an electromagnetic shielding layer to prevent the low-frequency interference (such as spark of motor brush) in the car from spreading to the antenna direction, while the antenna installed in the car (such as rear windshield) requires additional filter circuits, which is more costly and complicated. Low wind resistance design: Modern roof antennas mostly adopt the streamlined structure of shark fin (wind resistance coefficient ≤0.03), and the wind noise at high speed is ≤58dB, which is 8% lower than that of the traditional rod antenna, and has little impact on the fuel consumption of the whole vehicle (wind resistance contribution < 1%). Collision safety considerations: the position of the roof antenna is higher than the contact range of pedestrians, and the retractable design (such as some high-end models) can automatically retract in the event of collision, reducing the risk of injury to pedestrians, which meets the safety standards of the European Union such as ECE R127. Appearance integration: The roof antenna can be integrated with the luggage rack, roof trim and other components, or adopt glass printing technology (such as metal coating on the front windshield) to realize "invisible" signal reception and improve the appearance simplicity of the whole vehicle, especially favored by new energy vehicles.

Do I need an antenna for AM or FM? The frequency of the most commonly used civil walkie talkie antenna is 409-410MHz, and the optimal length of the walkie talkie antenna is between 36-37 cm or 18-19 cm. The signal is the best. Because Interphone antenna The signal received by the walkie-talkie antenna is the strongest only within the most suitable range. Why does the antenna need to be the right length? Because the range of the antenna length is related to the frequency and wavelength of the walkie-talkie. The frequency and wavelength of the walkie talkie determine the length of the walkie talkie mini antenna. For example, the working frequency of our civil walkie talkie is between 409 and 410MHz. Since the propagation speed of radio is approximately equal to the speed of light, the wavelength is simply the speed of light divided by the operating frequency. That is to say, the wavelength of the civil public walkie-talkie is about 0.73 meters. The signal is best when the optimum length of the pair long range walkie talkie antenna is between 36 and 37 cm or between 18 and 19 cm.

The signal receiving ability of Car Radio Antenna is not determined by a single factor, but the result of the joint action of several key design factors. Although the size of automobile antenna is an important factor affecting the receiving ability of radio signals, it is by no means the only decisive condition. In the precision system of car radio, FM AM Antenna is like a pair of "band catcher Gemini", which realizes the accurate capture of signal world with tacit division of labor. The working principle of this pair of golden partners is deeply bound to the "wavelength-frequency inverse proportion law" of electromagnetic waves-just like the relationship between the velocity of a river and the width of the river, the low-frequency AM signal is like a rushing river, the wavelength can reach hundreds of meters or even thousands of meters, and an antenna with enough length is needed as a "signal fishing net". By extending the physical size, the interaction range with electromagnetic waves is expanded, just like fishing a big fish in deep water with a long net, so that every inch of antenna becomes an effective carrier for capturing low-frequency signals. The essence of this design logic is to make the antenna length and the wavelength scale of AM signal form resonance matching: when the walkie talkie antenna length is close to 1/4 of the signal wavelength, the electromagnetic induction efficiency reaches the peak, just like the resonance principle of strings and sound waves, which makes the weak low-frequency signal excite stronger current oscillation on the antenna, thus dragging the distant broadcast signal into the receiving system. The high-frequency signal in FM band is like a smart jumping stream with short wavelength. At this time, the shorter antenna design can give full play to its advantages, just like catching small fish with a smart net, which can quickly respond to the changes of high-frequency signals and realize efficient reception. However, the vehicle-mounted environment is complex and changeable, and the signal Transmission is vulnerable to all kinds of interference. Pursue the ultimate size simply, just like paying attention to the fishing net size and ignoring the weaving process, which is far from enough to maximize the signal reception. Only by comprehensively considering more influencing factors can the antenna become the real "king of signal catchers". Parameters such as gain and standing wave are also the core factors affecting antenna performance. Gain reflects the antenna's ability to concentrate the input power, and high gain means that it can receive weak signals more efficiently. Standing wave reflects the matching degree between antenna and transmission line, and low standing wave ratio can reduce signal reflection and improve transmission efficiency. Only by comprehensively considering these parameters can the antenna performance be optimized. The directional design of Car Antenna can be called "directional radar" of car radio. Through precise technical optimization, it can accurately focus the signal in a specific direction like a radar locking the target, and greatly improve the receiving sensitivity. In the complex electromagnetic environment, this design can effectively shield the "noise interference" of signals in other frequency bands and resist the "turbulent impact" of electromagnetic interference, so that every note captured by the car radio is pure and clear, and the sound quality is always stable. The choice of materials is also a key link that affects signal transmission. High-quality conductive materials are like an unimpeded "high-speed passage", and metals with outstanding conductivity such as copper and aluminum are undoubtedly ideal building materials for building this passage. They can minimize the energy loss in the signal transmission process, make the signal transmission more efficient, not only capture weak signals quickly, but also ensure the stable output of signals, bringing users high-quality radio enjoyment.

Car Radio Antenna: from modeling to selection, an art of balancing industrial design and functional requirements The antenna of car radio has different shapes, but it is actually a subtle product of the game of industrial design, functional requirements and cost control. In terms of aesthetic shaping, automobile manufacturers are well aware of the value of antenna as a "mobile visual symbol"-since BMW introduced shark fin antenna into mass production models in 2002, with its smooth arc design, it not only reduced the drag coefficient by about 0.005Cd, but also made it a symbolic element of brand sense of science and technology; Retro models, such as Volkswagen T2 and Jeep herdsman, retain the classic long pole antenna shape, and pay attention to both functionality and nostalgic style through retractable design to attract specific consumer groups. From the technical dimension of signal reception, the FM AM Antenna shape needs to be accurately adapted to the characteristics of different frequency bands. The FM band (87.5-108MHz) is easily blocked by high-rise buildings, tunnels and other environments because of its short wavelength. With the effective receiving length of 1.2-1.5 meters, the traditional roof antenna can improve the signal capture efficiency by about 30%. However, the low-frequency signal in AM band (535-1605kHz) is sensitive to directionality, and the annular built-in antenna or rear window printed antenna (such as integrating metal wires into glass by etching technology) can effectively suppress electromagnetic interference and ensure the pure sound quality. At the level of engineering realization, safety and cost factors also dominate the design trend. Taking the high-speed driving scene as an example, the hidden shark fin Shark Antenna can reduce the wind noise by 25%-30% compared with the traditional long pole antenna; Although the research and development cost of the composite antenna integrated with tire pressure monitoring, GPS and other functions increases by 20%-30%, the number of parts is reduced through functional integration, which in turn reduces the later maintenance cost. Economical vehicles generally use printed antennas with a cost of only 5-10 yuan, giving consideration to signal stability and cost performance, and achieving a balance between technology and market demand. Faced with a wide variety of car radio antennas, consumers should choose based on the actual use scenarios and vehicle characteristics. If you often drive in remote areas with weak signals, the external long-rod antenna with high gain can significantly improve the radio reception effect; If the appearance is simple and beautiful, the integrated shark fin antenna or the printed antenna hidden in the rear window glass is a good choice; For car owners who need more high-speed driving, the antenna with low wind resistance can effectively reduce noise. It is worth noting that there are differences in antenna interfaces and signal protocols of different models. Before replacement, it is necessary to carefully consult the vehicle owner's manual or consult the 4S shop for adaptation information to ensure that the antenna specifications match the vehicle. When selecting the antenna of car radio, the material and process details can not be ignored. High-quality antennas are usually made of copper or alloy materials with good conductivity, and the outer layer is treated with anti-oxidation to ensure the stability and service life of signal Transmission; The cheap plastic antenna not only has poor signal receiving ability, but also is easy to age and break at high temperature. In addition, professional installation and debugging is very important for antenna performance. Some models need system matching after antenna replacement, otherwise there may be noise, signal interruption and other problems. It is recommended to leave it to experienced technicians to achieve the best radio reception effect.
