| 摘 要： | 针对微带天线辐射性能提高和雷达散射截面(RCS)减缩这一矛盾,文中将仿生学原理应用到微带天线结构设计中,并提出一种蝴蝶仿生结构的微带天线。该结构在贴片蝶形化的基础上,将蝴蝶在阳光下呈现的深色区域通过开槽方式除去。理论分析和仿真、实测结果表明,该方法设计的微带天线在辐射性能没有变化的同时,在4 GHz～8 GHz频率范围内单站RCS有了较大幅度的减缩,最大减缩量达到了23 dBsm。

| Abstract: | In order to solve the conflict between RCS(Radar Cross Section) reduction and performance of microstrip antenna,bionics principle is applied to antenna,and a bionic butterfly microstrip antenna is presented in this paper.The structure is cutting the fuscous area of butterfly in the sunshine away based on bow-tie patch.Simulation and measured results and analysis demonstrate that this bionic antenna can not only guarantee the antenna radiation performance,but also reduce the RCS of the antenna significantly ... |
