准八木天线的一种新型隐身技术

内容简介：设计了一款工作在X波段的准八木天线，针对该天线提出了一种新型的雷达散射截面（RC S ）减缩技术，根据天线分别工作在辐射状态和散射状态时金属反射板上电流分布的差异，对金属反射板进行了改进，在全频段内达到最大10．0 dB的后向RCS减缩，给出了原天线和改进后2款天线的增益、电压驻波比和RCS的仿真结果，证明了提出的RC S减缩技术的有效性。

Abstract：This paper designs an X band quasi-Yagi ,puts forward a new reducing technique of radar cross section (RCS) aiming at the antenna ,according to the difference of current distribution on the metal reflector w hen the antenna radiates or scatters ,modifies the metal reflector ,achieves maxi-mum 10 .0 dB backward RCS reduction in the whole frequency range ,gives the simulation result of gain ,voltage standing wave ratio (VSWR) and RCS of original antenna and two improved anten-nas ,proves the validity of proposed RCS reducing technique .
