“动中通”天线罩介电性能分析与比较

本文就移动卫星通信系统(简称动中通)中几种天线罩的结构形式、夹芯材料介电性能分别进行了分析与比较.分析和对比是采用理论分析、实物对比以及现场测试相结合的方式进行,测试的方法是利用同一套移动卫星天线系统,在同一环境条件下进行测试.结果表明:球形顶结构的芳纶纸蜂窝夹芯材料天线罩介电性能最为优良.

Analysis and Comparison of Redomes Dielectric Peoperty for Modile Satellite Communication System

In this paper, several different radomes for mobile satellite communication system are analysed and compared in the aspects of structural style,interlayer material, and dielectric peoperty. The comparison is based on the integration of theoretical analysis, real product contrast, and field test. The testing is made on the same mobile satellite antenna system under the identical environmental condition. The result shows that the aramid paper honeycomb interlayer material radome with spherical top structure has the best dielectric peoperty.
