摘　　要：提出利用开槽和加载短路探针等微带天线小型化技术,降低天线谐振频率,减小天线尺寸,抑制天线结构项散射从而实现天线雷达散射截面(RCS)减缩.在微带天线上应用此方法所得的仿真结果表明,使用该方法后天线工作频带内的RCS可降低4 dB左右,而天线的增益下降不到0.4 dB,从而保证天线的辐射性能的同时,明显地减小了工作频带内天线的雷达散射截面.The miniaturization technique of cutting slots and loading a shorting-post in the microstrip patch is used for the radar cross section（RCS） reduction of an antenna. It can reduce the working frequency and overall size of the antenna, which reduces the RCS by restraning structure mode scattering. Simulation results by applying the technique the microstrip antennas show that the RCS can be reduced about 4 dB and the gain loss is less than 0.4 dB, which illustrates that the compact antenna can not only guarante the antenna radiation performance, but also reduce the RCS of the antenna significantly at its working frequency.
