GPS + 4G LTE Magnetic Mount Combination Antenna

The performance of GPS antenna/GSM antenna is mainly affected by the following aspects Ceramic slice: the quality of ceramic powder and sintering process directly affect its performance. Currently, the ceramic pieces used in the market are mainly 25×25, 18×18, 15×15 and 12×12. The larger the ceramic plate area, the larger the dielectric constant, the higher the resonance frequency, the better the reception effect. Ceramic tiles are mostly square in design to ensure that the resonance in the XY direction is basically the same, so as to achieve the effect of uniform star collection. Silver layer: The silver layer on the surface of the ceramic antenna can affect the resonance frequency of the antenna. The ideal GPS ceramic chip frequency point accurately falls at 1575.42mhz, but the antenna frequency point is very vulnerable to the influence of the surrounding environment, especially in the assembly of the whole machine, it is necessary to adjust the shape of the silver coating to a…
