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 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. 

Key words: high gain; cross polarization level (CPS); wide broad beam; coplanar stripline (CPS); Balun
