基于坐标转换法研究三振子圆极化天线

Analysis on Triple Pole Circle-polarized Antenna Based on Orthogonal Coordinate Transform

文中通过直角坐标转换的方法,分析了一种三振子天线。通过推导出的解析解,对圆极化天线进行了Matlab仿真,发现该天线在两个坐标平面上都为圆极化场,可以在这两个平面法线方向同时进行极化分集接收,改善通信质量。

This paper analyses a triple pole antenna using orthogonal coordinate transform. Through simulating the analytic formula by Matlab, it is found that the electric fields on two orthogonal plane of the coordinate are both circle-polarized field. The communicationcan be improved by polarization division receiving signals on the normal direction of the two respective orthogonal planes.
