摘　　要：设计了一种圆极化(LCP)、采用边缘馈电的椭圆贴片天线。该天线采用单点馈电方式实现圆极化,无需外加相移网络和功率分配器,结构简单,成本低,适合小型化。对所设计的天线采用CST软件进行了仿真,从方向图、S参数值、轴比等方面进行分析,仿真结果验证了设计具有合理性,天线性能达到了设计要求。An elliptical edge-fed circularly polarized patch antenna is presented. The circular polarization with single-point-feed is used for the designed antenna. No external phase shift network and the power divider are needed. Its simple structure and low cost make it suitable to the small-size application. With help of the software tool CST, the antenna is simulated and can match the performance reauirements.
