Abstract

A novel microstrip patch antenna with a cross-slot cut in the patch is proposed and studied. The research results show that

compared with general microstrip antennas of satellite navigation

the new antenna with much wider band and smaller size has outstanding advantages

. The new patch antenna with a cross-slot cut in the patch was applied to the design of dual band navigation antenna for high-precision GNSS applications

and the impedance bandwidth and axial ratio bandwidth were effectively enhanced. The designed antenna had enough bandwidth to cover the all band of Global Navigation Satellite System (GNSS). Good performance of impedance

axial ratio

gain and phase center stability were obtained by simulation of HFSS. Simulation results show that the antenna has good circular polarization performance

and it is compact as well

so it is especially suitable for handheld high-precision navigation terminals and is promising in application.
