Total analysis of Router Antenna: a practical guide from principle to selection First, the core function of the antenna: the "transceiving center" of signals. Router antenna is the key transceiver of wireless signals, which can convert digital signals into electromagnetic waves and receive signals returned by terminals. It is not a simple amplifier, but a precisely designed oscillator, and its material and technology directly affect the signal radiation efficiency and anti-interference ability. Second, two mainstream antenna types Omni-Directional Antenna: it radiates signals evenly in 360 level, which is similar to a sprinkler spraying water in all directions and can cover every corner around. Suitable for home, small office and other point-to-multipoint scenes that need all-round coverage, so that mobile phones, tablets and computers in living room, bedroom and study can get stable basic signals. Directional antenna: the signal is highly concentrated in a single direction, which can enhance the signal strength in a specific direction and extend the Transmission distance. It is suitable for base station communication in remote mountainous areas involving Base Stations Antennas, equipment data interaction in large industrial parks, anti-interference in urban commercial centers and other scenes, which effectively guarantees stable signal transmission. Third, the antenna characteristics of different frequency bands 2.4G band: long wavelength, strong diffraction ability and good wall penetration performance, but the transmission rate is low, and it is easily interfered by Bluetooth and microwave oven, and the antenna pays more attention to signal coverage. 5.8G frequency band: short wave length and fast transmission rate, but large wall-penetrating loss and limited coverage. The antennas are mostly designed with multiple arrays, and the signals in specific directions are enhanced by beamforming technology. Fourth, the number of antennas: not the more the better. The signal coverage ability of router is determined by the number of antennas, transmission power, chip performance and software algorithm. Multi-antennas are often combined with MU-MIMO technology to realize high-speed transmission of multiple devices at the same time, but when a single device is connected, the signal strength is limited. In addition, the antenna layout and angle are very important. For example, vertical antennas are suitable for horizontal space coverage, and 90-degree cross placement can take into account both horizontal and vertical signal coverage. Fifth. Suggestions on practical choices Home scene: Choose a dual-band Omni Directional Antenna router, giving consideration to coverage and transmission speed, to meet the needs of daily Internet access and video playback. Large apartment or complex environment: it can be used with Directional Antenna expander to enhance weak signal area, or Mesh networking can be used to achieve seamless coverage. Professional application: For enterprise monitoring, long-distance wireless transmission and other scenarios, high-gain directional antenna is preferred to ensure signal stability. FAQ: What is the core function of router antenna?
