| 摘 要： | 为了减小微带贴片天线的雷达散射截面(RCS)，利用电磁带隙结构(UC-EBG)的带阻特性，提出用UC-EBG代替普通金属作为微带贴片天线的地板．当天线工作频带内的电磁波入射时，UC-EBG地板呈现出带阻特性，不影响天线的正常工作;而在该频带以外，UC-EBG地板具有良好的带通特性，对入射电磁波起透射作用，从而可以达到减小天线带外RCS的目的．仿真和测量的结果吻合良好，证明了此方法的有效性．

| Abstract: | To reduce the RCS(Radar Cross Section) of a microstrip patch antenna,the UC-EBG structure is used as the ground plane of a microstrip patch antenna because of the stop-band property of the UC-EBG.In the pass-band,the UC-EBG can let many more incident waves pass.Therefore,it can effectively reduce the RCS of the microstrip patch antenna outside operating band.The simulated and measured results are in good agreement with each other and show that this method is effective. |
