Abstract
In order to improve the performance of circularly polarized microstrip antennas, a novel circularly polarized slot loaded triangular microstrip antenna is presented.The circular polarization band-width is widened by loading the slot and branch on the triangular patch.The overall size of the antenna is 0.74λ0×0.88λ0×0.09λ0. HFSS simulation results show that the antenna impedance bandwidth(S11<-10 dB) is 9.6%,the circular polarization bandwidth(AR<3 dB) is 5.4%,the minimum AR is 0.23 dB, the maximum gain is 8.11 dBic. The antenna has good application potential in satellite navigation and wireless communication because of its good circular polarization performance.关键词
