摘　　要：设计了一种紧凑馈电网络的宽带毫米波圆极化微带阵列天线,采用缝隙耦合馈电的宽带圆极化微带天线单元和紧凑的S形曲线并联等相差圆极化馈电网络构建了2×2的宽带圆极化微带阵列天线,分析了各个参数对天线特性的影响,获得了较好的宽带圆极化特性。并以该2×2天线阵列为基本子阵,通过并联馈电网络扩展到4×4的宽带圆极化微带天线阵列。实测和仿真结果基本一致,实现了良好的宽带圆极化特性。Design of an extensible millimeter wave broadband circularly polarized microstrip antenna fed by aperture coupling was proposed. A 2 × 2 element compact and efficient feed network microstrip anten- na array was designed. The influence of key parameters on antenna was analyzed, and obtain a broad- band and good circular polarization. Based on the 2 × 2 element antenna array, the broadband circularly polarized microstrip antenna array is extended to 4 × 4 element antenna array by parallel feed network. The measured and simulated results are basically consistent.
