| 摘 要： | 基于腔模理论提出一种简单、方便的单馈圆极化微带天线的等效电路,同时给出基于等效电路的轴比特性计算公式。设计了一种中心频点为2.43 GHz，轴比带宽为30 MHz的单馈圆极化微带天线,对其轴比特性采用等效电路分析计算与全波仿真和实测得到的结果基本一致,从而为圆极化微带天线轴比特性的获取提供了一种新的方法,极大的方便了天线设计过程中的调试。

| Abstract: | This paper introduces a new kind of equivalent circuit of single-feed circular polarization micro-strip patch antenna (CPMA) based on Cavity Model Theory and gives the calculating formula of axis ratio. Meanwhile, a novel circular polarization micro-strip antenna is designed. The axis ratio calculated based on equivalent circuit agrees with the simulated and measured results. The above provides a new method for debugging the axis ratio of circular polarization micro-strip patch antenna. |
