Analysis of radiation characteristic of conducting wire antenna using MoM

采用矩量法对线形导体上的辐射特性进行了分析,该方法是基于伽略金法,以三角矢量函数作为空间的基函数和检验函数对任意形状的线结构的电场积分方程进行求解,并以此求解天线上的电流分布和天线的功率辐射方向图。给出了篇例,结果表明,该方法是有效的,为超宽带天线的分析奠定了基础。

In this paper, the method of moment is employed for analyzing the electromagnetic character of wire structure conductor . This solution method is based on Galerkin＇ s method, and piecewise triangle vector functions are used for spatial expansion and testing functions for arbitrary shape wire structures, in order to get the results of the current distribution and power radiation. The results show that this scheme is efficient, and gives a way to analyze UWB antenna.
