Abstract


As satellite navigation technology and industry rapidly progressed, the demand of the navigation antenna is getting a rising increase. The antenna of multi band miniaturized navigation has become a mainstream design. This paper optimized designs a microstrip navigation antenna which works on Beidou B1 (1.561GHz) and B2 (1.207GHz) frequency band. It uses multilayer microstrip patch to achieve dual frequency work of antenna and adopts doubly fed point to realize the circular polarization of the antenna. The simulation results demonstrate that the performance of the designed Beidou antenna meets the requirements of industrial application.
