摘　　要：该文介绍了一种用于电子战诱饵中的宽带宽角迭层微带天线。为了展宽天线的带宽，采用双层圆形贴片电磁耦合天线。通过了有限接地板对双层圆形贴片电磁耦合天线辐射方向图影响的实验研究，成功地解决了展宽这种天线辐射方向图的问题。结果表明该天线的电性能指标（包括增益、输入驻波比、带宽和方向图）和结构都满足了使用要求。A broadband and broad beam two layer microstrip antenna in electronic warfare decoy is presented in this paper. A two layer electromagnetic coupled circular patch microstrip antenna is adopted to widen the frequency band of the antenna. The finite ground plane effect on the two layer microstrip antenna radiation patterns is studied experimentally, which widens the radiation patterns successfully. The result shows that the antenna completely meet the user's demand.
