1. Ceramic sheet The quality of the ceramic powder and the sintering process directly affect the performance of the Inside GPS Antenna. The larger the area of the ceramic sheet, the greater the dielectric constant, the higher the resonance frequency, and the better the acceptance effect. 2. Silver layer The silver layer on the surface of the ceramic antenna can affect the resonant frequency of the antenna. The frequency point of the ceramic chip with good effect is 1575.42MHz, but the frequency point is easily affected by the environment. The shape of the silver surface coating must be adjusted to keep the frequency point at 1575.42MHz. 3. Feed point The ceramic antenna collects the resonance signal through the feed point and sends it to the back end. Due to impedance matching, the feed point is generally not in the center of the GPS Antenna SMA, but slightly adjusted in the XY direction. Such an impedance matching method is simple and does not add cost. 4. Amplifying circuit The shape and area of the PCB carrying the ceramic antenna. Due to the characteristics ofInside GPS Antenna , when the area of the ceramic sheet is 7cm×7cm without interruption, the performance of patchGPS Antenna Fakra can be maximized. So keep the area and shape uniform. The selection of the gain of the amplifier circuit must match the gain of the back-end LNA. Sirf's GSC3F requires that the total gain before signal input should not exceed 29dB, otherwise the signal will be oversaturated and self-excited
