左手微带天线设计及其RCS计算OA北大核心CSCDCSTPCD
Design of Left-handed Microstrip Antenna and Calculate of Its RCS
基于左手传输线结构,设计了左手微带天线单元及其4×4阵列,并对单元天线和阵列天线的辐射特性和散射特性进行了数值仿真计算与实际测量.数值仿真与实测结果表明,相比于矩形微带天线,左手微带天线在不影响辐射性能的情况下,大幅度地降低了天线带外的雷达散射截面(RCS).左手微带天线克服了现有微带天线RCS缩减技术中的不足和缺陷,是在不损失天线辐射性能的前提下降低RCS的有效选择方案.
Firstly,a left-handed microstrip antenna (LH-MSA) and a4×4 LH-MSA array are desigend baaed on left-handed transmission line structure.Then the radiation performance and scattering property of element antenna and array antenna are simulated and measured.Simulation and measurement results show that compared to rectangular microstrip antenna,LH-MSA drastically reduce the radar cross section (RCS) without affecting the radiation performance.LH-MSA overcome…查看全部>>
