矩形腔十字裂缝天线的研究

内容简介：随着卫星移动通信技术的发展，一种能适合机载和地面移动载体卫星通信的天线越来越受到人们的青睐。该种天线要求具有宽频带、圆极化和电扫描跟踪等特性。矩形腔十字裂缝天线就是这种天线理想的辐射单元之一。基于矩量法的分析途径，本文提出了计算矩形腔十字裂缝天线的数值方法，给出天线单元的输入阻抗、增益和轴比等辐射特性的数值结果，并进行了实验验证。理论和实验结果有着很好的一致性。

Abstract：With the development of the mobile satellite communication technology,it is of current interest to research into an antenna system for communication both ground-based mobile and airborne application,in which a broadband,circular polarization,electronically steering etc.are desired.A rectangular cavity crossed-slot antenna is one of ideal antenna elements for this antenna system.Based on the analytical procedures of moment method,a numerical method for calculation of the rectangular cavity crossed-slot antenna is presented.The theoretical results of the radiation characteristics such as input impedance,gain and axial ratio of circular polarization are given,which are validated by experimentation.It can be found that theoretical results agree with experimental results well.
