摘要
为实现引信天线对前向半空间的波束扫描功能,达到针对不同飞行速度目标的作战需求,文中设计了一种新型多波束天线系统。通过采用微带蛇形线天线实现毫米波引信单一波束的前倾设计,利用微带蛇形线周向尺寸小的特点,将不同波束倾角的蛇形线天线平行布局于一块微带基板上,通过馈电点的快速切换,实现波束扫描功能。通过对集成多波束天线的有限元仿真表明,天线实现了三种倾角的引信探测波束,是一种实用可行且性能优良的新型天线形式。
A new multi-beam antenna system was designed to realize the function of beam scanning on the forward space for fuze antenna. Since the serpent line antenna has the advantage of small size, we dispose serpent lines with three different beam slope angle on one dielec- tric-slab. By switch of fed point,the function of multi-beam scanning in front half space can be realized. Simulation of FEM software shows that the antenna realizes the design of three angle of fuze detection beam. The new antenna is practically feasible and has excellent performance.
