| Abstract: | In this paper,a high-gain antenna structure composed of a circularly polarized microstrip antenna and a metamaterial cover is presented.This antenna is simulated by Ansoft HFSS simulation software.The simulated results demonstrate that the metamaterial cover increases the gain of the plain circularly polarized microstrip antenna from 7.8dB to 11.4dB,meanwhile the circular polarization characteristic is maintained,and this antenna is of simple structure and easy to be fabricated. |
