| 摘 要： | 提出一种高增益、共面带状线（CPS）馈电的双环形印刷天线.该天线具有10.8 dB的高增益，在一定的功率密度下可以接收到更多的功率.交叉极化低于-38 dB，同时波瓣宽度大于70°，从而避免了严格的主波束校准问题.该天线适用于迅速发展的无线通信系统.为了便于测试，为天线设计了CPS 微带线巴伦.实测与仿真结果比较吻合.

| Abstract: | A dual-loop printed antenna fed by coplanar strip-line(CPS)with hish gain is proposed.This antenna has a high gain of 10.8 dB,capable of receiving more power at certain power density.It has a low cross polarization level that is less than-38 dB,and a broad beam width of more than 70°halt-power beamwidth(HPBW)which does not require strict alignment of the main beam.This antenna can be used in communication systems.Balun from the CPS to a microstrip line is designed.The measured results are in agreement with simulations. |

| Keywords: | high gain cross polarization level(CPS) wide broad beam coplanar strip-line(CPS) Balun |
