摘　　要：介绍了基于腔模理论的圆形微带天线的辐射原理,并在此基础上给出了圆极化的实现机理。在GPS所使用的波段,对单点馈电的圆极化微带天线进行了仿真,测量了电压驻波比和方向图,并对测量结果进行了分析。Based on the cavity mold theory,the radiation principle of circular microstrip antenna was introduced. The realization mechanism of circular polarization was given. Within the wave band of GPS, the simple-point feeding circular polarization mierostrip antennas was designed by Ansoft HFSS;The voltage standing-wave ratio and the directional diagram were measured, and analysis on the measurement result was conducted.
