What is the normal gain of a GPS antenna? What are the factors that affect performance?

Introduction: GPS is used in all aspects of life. This is actually what we call a navigation system. By receiving satellite signals, positioning and navigation are completed. An antenna is required to receive signals, so we call this antenna a GPS antenna. In order to ensure the accuracy of the results and ensure a strong signal, it is necessary to understand the GPS antenna gain. What is normal? What factors will affect the performance?

　　1. Ceramic sheet

The quality of ceramic powder and the sintering process can directly affect the GPS antenna gain. There are many specifications of ceramic sheets used on the market today. The larger the area, the greater the dielectric constant, and the better the reception effect will be. The design is generally square in order to ensure consistent resonance in the direction and achieve uniform signal reception.

　　2. Amplification circuit

The shape and area of ​​the GPS antenna carrying ceramics, because GPS has the characteristics of bottoming out, so when the background continues to amplify, the gain effect of the GPS antenna can be further maximized. Although it is restricted by the appearance structure and other factors, we should try to keep the area equal and the shape uniform.

　　3. Silver layer

The GPS antenna gain will be affected by the silver layer on the surface. The normal frequency point should be 1575.42 Hz, but this is easily affected by the surrounding environment, especially the shape of the rock layer coating within the entire muscle.

Through the above text introduction, you should already know how much GPS antenna gain is normal and what factors affect it. In order to ensure a better signal for normal use, correct installation should be done.
