摘　　要：为了提高圆极化微带天线性能,提出一种新型圆极化微带天线结构,通过在三角形贴片上加载缝隙和枝节展宽圆极化带宽,天线总体尺寸为0.74λ0×0.88λ0×0.09λ0。HFSS仿真结果表明该天线阻抗带宽(回波损耗S11<-10 d B)9.6%,圆极化带宽(轴比AR<3 d B)5.4%,轴比最小值0.23 d B,增益最大值8.11 d Bic。该天线的圆极化性能较好,在卫星导航和无线通信中具有很好的应用潜能。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 bandwidth 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(S 11<-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.
