摘　　要：为实现弹载引信天线共形安装,解决常规毫米波平面微带引信天线带来的馈线寄生辐射及波束指向单一问题,提出一种多层低剖面带状微带混合结构天线形式。基于场路结合理论,开展天线射频电路参数计算,通过有限元仿真建立系统模型并进行验证。经计算测试,带状微带混合结构形式天线可精确控制天线的口径场分布,方向图实现两种波束倾角,主副电平比高于16 dB,天线带宽大于700 MHz。In order to realize the conformal installation of missile-borne fuze antenna and solve the problem of feeder parasitic radiation and single beam pointing caused by conventional millimeter-wave planar microstrip fuze antenna,a multi-layer low-profile banded microstrip hybrid antenna form is proposed.Based on the theory of field-circuit combination,the parameters of antenna RF circuit are calculated,and the system model is established and verified by finite element simulation.The calculation and test show that the band microstrip hybrid antenna can accurately control the aperture field distribution of the antenna,the pattern realizes two kinds of beam inclination.The ratio of main level to secondary level is higher than 16 dB,and antenna bandwidth is more than 700 MHz.
