How can GPS ceramic antenna receive better signals? [Copy link]

Nowadays, our mobile phones, cars or navigation devices all use navigation antennas. Among them, GPS ceramic antennas are widely used due to their advantages such as fast satellite reception speed, high positioning accuracy, good stability and high reliability. However, many friends have recently found that GPS ceramic antennas sometimes do not receive signals well when using them. In fact, this is normal. Of course, there are ways to improve it. How to do it? The technicians of Jingzhong Ceramic Antenna Factory will tell you:

GPS Ceramic Antenna

When installing the GPS ceramic antenna, you can get a good effect by just pointing the ceramic surface towards the sky. If conditions permit, you can place the ceramic antenna in the open air to reduce the impact of signal blocking. If it is placed in the car, it is best to place it close to the glass surface and avoid other objects blocking the ceramic surface. This can also maximize the reception effect of the GPS ceramic antenna.

The factors that affect the reception effect of GPS ceramic antenna include ceramic sheet, silver layer, amplifier circuit and feed point. The larger the area of ceramic sheet, the greater the dielectric constant of GPS ceramic antenna, the higher the resonance frequency and the better the reception effect. The amplifier circuit is the shape and area of PCB that carries GPS ceramic antenna. Because GPS has the characteristic of ground rebound, the performance of GPS ceramic antenna can be brought into full play when the background is 7cm×7cm uninterrupted ground.

In addition to the above factors, during installation, the signal receiving surface of the GPS ceramic should be parallel to the ground to achieve the best reception effect; at the same time, the surrounding environment should also be considered, whether there are obstructions, such as metal, woods, etc., which will also affect the antenna's reception effect.
