摘　　要：基于天线的辐射接收理论，研究微带天线散射的分析与控制，提出了微带贴片天线RCS减缩思路。通过在地板上添加矩形结构，调整天线的谐振频率，减小贴片尺寸，设计了1幅具有低RCS特性的微带天线。与谐振在同频率的微带贴片天线相比，天线的增益降低0．7dB，而天线在2～10GHz频带内的最大RCS降低10dBsm。In this paper, based on the theory of antenna radiation and scattering, the method of analyzing and controlling the scattering of microstrip antenna is also given and the way of microstrip patch antenna RCS reduction is introduced. By adding the rectangular slots on the ground, adjusting the resonant frequency and reducing the size of the patch, a microstrip patch antenna with low RCS is designed. The gain suffers 0.6 dB, and the maximum RCS is 10 dBsm lower when compared to the standard path antenna with the same resonant frequency.
