摘　　要：利用有源方向图法对X波段Vivaldi天线阵列互耦问题进行了分析,提出了加载DGS结构的Vivaldi天线阵的去耦方法,分析了互耦对阵列天线方向图增益、波束宽度、副瓣电平等特性的影响.理论分析和仿真结果表明,该方法可以有效地减小Vivaldi天线阵列的耦合,对天线阵列设计有一定的实用价值.A decoupling method was proposed for Vivaldi antenna array integrated with rectangle defected ground structure （DGS）. The influence of coupling problems on array patterns, antenna gain and side lobe level was analyzed. The simulation results show that this method can effectively solve the coupling problems between Vivaldi array elements. This method can also be used in any other antenna arrays designs.
