【摘要】 传输损耗是天线罩的重要性能指标之一。简述了Ka波段某动中通天线罩的基本特性。介绍了远场法测量天线罩传输损耗的原理方法。对天线罩测量误差进行了分析,结果表明其总均方根误差≤0.116dB,最后给出了Ka波段某动中通天线罩插入损耗测量结果,测量结果同理论预算基本吻合。更多还原

【Abstract】 Transmission loss is one of the key performances on antenna radome.In this paper,basic characteristics of Ka-band one Satcom on the move antenna radome are described simply.Principle and method of measuring antenna radome transmission loss are introduced using direct far field method.The error of antenna radome measurement is analyzed.the result show that RMS of antenna radome measurement is less than 0.116 dB.At last,transmission loss measurement result for Ka-band one satcom on the move antenna radome are given,measuring results agree basically with theory result更多还原
