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.A dual-loop printed antenna fed by coplanar strip-line （CPS） with high 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° half-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.
