摘　　要：提出一种基于可重构机理的微带天线RCS缩减技术,该可重构微带天线的微带贴片和地板全部碎片化,并通过MEMS开关连接.仿真结果表明:在观测频带内,该可重构微带天线RCS峰值较传统微带天线的平均缩减5.8 d B,在典型频点上,最大缩减20 d B,该可重构微带天线在低RCS智能蒙皮天线方面具有较大的研究潜力.The microstrip patch and the ground of the reconfigurable microstrip antenna are all fragmented,and they are connected with the MEMS switches. The simulation results indicate that,within the observed band,the RCS peak value of the reconfigurable microstrip antenna is reduced,on average,by 5. 8 d B than that of the conventional microstrip antennas,and the RCS peak value has the maximum reduction of 20 d B in a representative frequency. We conclude that the reconfigurable microstrip antenna has greater research potential in the low RCS smart skin antennas.
