摘　　要：针对以前传统的微带共形阵在弹道修正弹和遥测等应用平台上安装困难及抗高过载的问题,提出了一种弹丸头锥上对称配置的S波段微带天线阵。该微带天线阵采用天线单元与微带功分器分离的形式,两个天线单元介质基片焊接在23 mm×30 mm的钢片上,用螺钉固定在头锥上铣削出的小平面上,在头锥两侧对称布置。微带功分器放置在锥体内部,天线单元通过背馈方式与微带功分器连接,进行等幅同相馈电。仿真、测试与试验表明:S波段弹丸头锥上对称配置的抗高过载微带天线阵性能指标优良、安装工艺简单且具有抗高过载能力,该研究成果可应用于各种尺寸的遥测和弹道修正弹的弹载共形微带天线阵设计。In view of the traditional microstrip conformal antenna array applied on trajectory correction projectile and telemetry platform has difficulties on installation and anti-high overload,a S-band mocrostrip antenna array which was symmetrically configured on projectile nose cone was put forward in this paper.The antenna unit was separate from the microstrip merit minute,two antenna units＇ medium substrate were welded on 23 mm×30 mm steel disk,with screw retention on the symmetrical facet of the nose cone.Simulation and experiment results indicated that the S-band microstrip antenna array which symmetrically arranged on projectile nose cone had good performance indexes,high overload resistance,and was easy embeded.The research could provide reference to conformal microstrip antenna array design of different sizes telemetry projectile and the trajectory correction projectile.
