摘要 用矩量法(MoM)结合离散复镜像理论(DCIM)研究了有耗地面上方水平接地天线的性能以及天线之间的互耦。由离散复镜像理论得到了分层媒质中空域磁矢位格林函数和电标位格林函数的闭合表达式,避免了直接作索末菲积分。讨论了对接地点的处理方法,提出以集中加载的接地电阻来描述接地点地网特性,并在天线末端附加一个电流项,此外无须再寻求任何关于末端电流的终端条件。提出采用分段辛普森数值积分方法来计算检验源和展开源重合时的阻抗矩阵元素。最后给出了部分计算结果,并与文献数据进行了对比。 The characteristic of horizontal wire antenna above multi-layered medium with its end connected ground is analyzed in this paper by using MoM and discrete complex image method （DCIM）. The spatial Green functions are given by Prony method and calculation of Sommerfeld integral is avoided. To simulate the grounding point, a new method is provided. In the end, theoretical calculation and literature data are analyzed and compared.
