基于腔模理论本文提出了理想单馈圆极化天线的等效电路,并且给出了轴比参数和反射系数的计算公式,同时推导得到了单馈圆极化天线等效电路轴比与反射系数关系。从而实现利用电路参数计算得到的反射系数来预估轴比曲线参数的目的。将结果与电路参数计算得到的轴比进行对比,验证了结论的正确性。

This paper introduces a new equivalent parallel series circuit of the single-feed circular polarization microstrip patch antenna based on Cavity Model Theory and gives the calculating formulas of axial ratio and reflection coefficient.The relationship between axial ratio and reflection coefficient of the single-feed circular polarization microstrip patch antenna is also analyzed in the paper.So,the axis ratio can be estimated according to reflection coefficient calculated by the formula put forward in this paper.The comparison between this result and that calculated with circuit parameters validates the correctness of the method.
