A study of the phase center of the antenna feeder for a deformed reflector

本文提出了任意形状变形反射面天线馈源的相位中心定义,给出了反射面天线结构在由于荷载作用而引起变形情况下,天线馈源的相位中心的计算方法。此外,本文将该计算方法实际应用于某天线的工程计算中,取得了较为满意的数值结果。

This paper first presents the definition of the phase center of the antenna feeder for a deformed reflector of an arbitrary shape. Then the computational approach of the phase center is studied under the multiple loading conditions. Finally, the method is applied to the engineering computation oF an antenna to demonstrate the algorithm.
