How to design Beidou positioning antenna? What design principles should be grasped?

Introduction: In the actual design process of Beidou positioning antenna, it is basically necessary to combine the rich experience of the industry and the relatively unique theoretical knowledge for design. So what principles should be grasped during the design process?

　　1. Understand common antenna types

The wide range of designs covers a variety of different design types. Even the Beidou positioning antenna will have various types when designing. If you want to design well, you must understand the size or efficiency and other aspects. Only in this way can all designs be analyzed in multiple aspects, so that the entire antenna can exert its best performance.

　　2. Consider internal circuit board construction

The internal circuit board structure of the Beidou positioning antenna is more important, because usually the trace lengths of different circuit boards will determine the frequency of each antenna. The higher the frequency, the shorter the trace length, and the wider the area each antenna needs to retain on the entire device, so the surrounding area may be taken into consideration.

　　3. Choose a suitable surface

When all Beidou positioning antennas play a role, they must ultimately be related to the ground plane, because they must have an effective flat ground plane. The shape or size of the ground plane relative to the antenna will directly affect the performance or impedance of the original antenna. The ground plane should correspond to the edge of the antenna, so that they can be kept away from the entire area.
