摘　　要：针对弹载卫星接收天线小型化、方向图覆盖及抗高过载的综合性问题,提出了弹丸前端抗高过载北斗接收天线。该天线基于微带振子天线原理,利用天线曲流技术将天线振子折线形成伞形微带振子,同时在天线背面的振子天线内侧通过开槽形成电容加载,缩小了天线尺寸,并采用对称微带振子馈电结构实现了天线方向图在赤道面为圆形,子午面为“∞”字形的全向辐射。仿真、测试与试验表明,弹丸前端抗高过载北斗接收天线性能指标优良,具有体积小、易加工安装、方向图稳定等特点,在承受高过载的发射条件下满足产品全弹道卫星定位。研究成果可应用于不同榴弹平台的卫星接收天线设计。Aiming at the comprehensive problems of miniaturization,pattern coverage and anti-high overload of missile borne satellite receiving antenna,an anti-high overload Beidou receiving antenna for projectile front end was proposed.Based on the principle of microstrip dipole antenna,an umbrella shaped microstrip dipole antenna was formed by meandering the antenna and loading capacitance on the back of the antenna,so as to reduce the size of the antenna.Using symmetrical microstrip dipole feeding structure,the antenna pattern was circular in equatorial plane and“∞”in meridian plane.The simulation results indicated that The Beidou receiving antenna with high overload resistance at the front end of the projectile had excellent performance index,small volume,easy processing and installation,and stable pattern.Under the condition of high overload,it could meet the requirements of full ballistic satellite positioning.
