摘　　要：分析缝隙加载方法减缩微带天线雷达散射截面(RCS)的基本原理和规律。分别介绍四种不同加载形式,综合利用其中两种形式对微带天线RCS进行减缩。在天线增益只下降0.2dB,其它工作性能基本保持的情况下,微带天线RCS在很宽的频带内得到较大幅度的减缩。The theory and regularity of embedding slots to reduce the radar cross section（RCS） of microstrip antennas are analyzed and the method is utilized to reduce RCS of mierostrip antennas. After introducing four different forms of embedding slots,the two forms of them are synthesized to reduce RCS of microstrip antennas. On the occasion that the drop of antenna＇s gain is 0. 2dB and other performance is kept basically, RCS is reduced greatly through a very wide frequency band.
