摘　　要：采用离散复镜像方法 (DCIM)计算微带结构的空间域格林函数 ,提高了计算阻抗矩阵的速度。采用三角矢量面元 (RWG)基函数 ,模拟电流分布。由于三角形可以模拟任意形状的贴片 ,本文的方法可以准确地计算任意形状贴片的散射。数值结果证实了本文方法的有效性。Discrete complex image method is used to compute the Green’s functions in the spatial domain, which improves the speed of computing the impedance matrix. The triangle vector basis function (RWG) is employed to simulate the current distribution. As the triangles can be used to model arbitrary shape patch, the method in this paper is able to compute the scattering properties of arbitrary shape microstrip patch. The numerical result shows the validity of the method in this paper.
