边缘馈电圆极化椭圆贴片天线的设计

内容简介：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。

Abstract：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 requirements .
