摘要/Abstract

摘要： 提出了一种反射面天线机电耦合分析的新方法.该方法基于反射面天线的结构分析,利用变形反射面单元的节点位移信息得到变形后的反射面的网格模型.在此基础上,通过使用物理光学法直接计算出变形反射面天线辐射场.该方法与现有分析方法相比,能够更真实地描述出天线变形对其电磁性能的影响.通过对7.3 m抛物面天线的仿真,验证了该方法的有效性.

Abstract: A novel approach to the electromechanical coupling analysis of reflector antennas is presented.Based on the structural analysis of the reflector antenna,a mesh model of the distorted reflector is obtained through the node displacement of elements of the distorted reflector.Moreover,the radiation field of the distorted reflector antenna is calculated by the physical optics method.This method reveals the effect of the reflector distortion on the electromagnetic performance more factually comparing with the traditional methods.The simulation on a 7.3 m parabolic antenna validates the effectiveness of the approach.
