摘　　要：针对天线罩对天线电性能的影响问题,提出采用天线的驻波参数来评价天线罩性能的新途径。在采用微波网络理论对天线罩进行分析的基础上来选定具体形式的天线罩。利用矩量法对选定的U形天线罩进行了研究,得出了天线罩的宽度、高度及厚度在不同频率下与天线驻波的关系。通过设计出符合要求的天线罩证明了算法的有效性。Aiming at the effect of antenna radome to antenna characteristics, a novel methed to appraise the performance of antenna radome through studying antenna＇s voltage standing wave rate is presented. Based on the analysis to antenna radome by using the theory of microwave network, a particular shaped antenna radome is selected. An experimental study is undertaken on a select U shaped antenna radome with the method of mo ment, and the relation beteewn the voltage standing wave rate and the width, height and thickness of an antenna radome under variant freguency is obtained. The effectiveness of the proposed algorithm is verified by an anten na radome designed.
