摘　　要：弹载天线的天线罩是天线的重要组成部分,由于尺寸的限制,天线罩距离天线辐射体非常近,甚至紧贴辐射体,因此天线罩对天线的辐射具有严重的影响。给出了一种适合于弹载的小直径螺旋天线的设计参数,利用矩量法分析了天线罩对天线电气性能的影响,并进行了实际设计和测试,验证了分析结果,指出在这种天线的设计时要充分考虑天线罩的电气性能。The radome of missile-borne antenna is an important part of the antenna, and has a significant impact on the radiation of the antenna, because the radome is close or even cling to the radiators of the antenna due to the limited size. In this paper, the design parameters of the helical antenna with small diameter suit applicable to missiles are presented, then the impact of the radome on the electric performance of the antenna is analyzed using moment method. And the results of actual design and measurement which can validate the analysis results are given. Finally the conclusion is drawn that the electrical performance of the radome must be considered sufficiently.
