| 摘 要： | 本文给出了一种分析微带印刷天线辐射与散射的数值方法。此方法将印刷天线按三角网格剖分，在导体表面建立积分方程，用全波离散镜像理论给出微带结构的空域格林函数的闭合表达式，未知电流用三角网格上的矢量电流基函数展开并用矩量法求解。与以往的矩形网格上基函数展开相比，此方法能更有效地逼近任意形状的微带结构，最后给出了几个数值结果

| Abstract: | A numerical analysis of radiation and scattering of microstrip printed antenna is presented. The microstrip printed antenna is rendered in a triangular discretization. The mixed-potential integral equation on the conducting surface is solved by expanding unknown currents with triangular-domain basis functions in a method of moments. To enhance the computational efficiency, the full wave discrete image technique is used to expross the closed form spatial-domain Green's function of the mierostrip structure. Compaaring with rectangular-domain modeling,this method is able to conform readily to arbitrarily shaped microstrip printed antenna. Some numerical results are given at last. |
