Abstract

Beidou satellite navigation system is a Chinese self-developed global satellite navigation system. Now it has its place in mature satellite navigation system. In recent years, more and more people pay attention to it. The development of Beidou satellite navigation system has good prospects, so designing the Beidou terminal antenna is of important values both for research and applications. In this paper, a Beidou circularly polarized microstrip antenna is designed ,which is made by cutting an asymmetrical U-slot in a square radiating patch and diagonal corner cut method to achieve circular polarization and to reduce the size of the antenna. Finally the model of the antenna is made and analyzed by HFSS15.0 to get the optimum performance parameters
