摘要
文章介绍了基于腔模理论的矩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;再对测量结果进行了简单分析。
Based on the cavity mold theory, the rectangle microstrip antenna radiation principle is introduced; And on this foundation, the circular polarization realization mechanism has been given; In the wave band of GPS, the simple point feeding circular polarization microstrip antenna is simulated;The voltage standingwave ratio and the directional diagram is measured; And the simple analysis to the measurement result is given at the same time.
