摘要
针对超短波频段信号的通信需求,分析了工作于该频段的机载天线一般的设计选型要求.针对机载平台的平台特性,从装机适应性角度阐述了几种特高频(Ultra High Frequency,UHF)频段天线在装机之后受周围遮挡物以及周边机身的影响,指出了天线的覆盖性能.同时根据上述分析的结果,提出了天线优化布局的改进优化设计建议,从而提高UHF天线装机之后的覆盖性能,提升对应频段信号的通信能力.
According to the communication requirements in the ultrashort wave band,the general selection requirements of airborne antennas in the ultrashort wave band are analyzed.The influence of aircraft fuselage and surrounding structure on several ultrashort wave band airborne antennas and the coverage performance of the antennas are analyzed form the view of airborne antenna disposition.For the results of the analysis,suggestions for the optimization positions of the airborne antenna are given.The layout improve the ultrashort wave band antenna coverage and enhance the communications.
