圆极化馈线系统的微调

The Adjustment of the Circular Polarization Feed Systems

借助网络矩阵理论，分析了圆波导的小椭圆度对馈线系统相、幅特性的影响，提出并论证了在圆波导上进行微量压椭来优化圆极化特性参数的简捷而有效的方法。实验表明，效果甚好。

With the aid of network matrix theory, the effect of slight ellipticity of the circular waveguide on the phase and amplitude of the feed systems is analyzed.To improve the circular polarization parameters of the feed systems,a simple and effective method,making the circular waveguide slightly approachs the one with expected quesl-ellipticity,is developed further.It is proved through experiments that the method is highly effective.
