摘　　要：利用矩量法对有限大导体板上单极天线的阻抗特性进行了研究。基于Pocklington积分方程和Galerkin法 ,采用分域基正弦函数展开模式 ,得出了有限尺寸导体板上单极天线的电流分布和输入阻抗 ,并对单极天线在不同长度及不同导体板上的情况进行了研究。结果表明 ,单极天线的长度及导体板的形状及大小在一定程度上影响了单极天线的特性。Abstrac In this paper, the characteristics of monopole antenna on a finite square plate are studied by using the method of moment. Based on the Pocklington equation and Galerkin method, the current distribution and input impedance of the monopole antenna are calculated by employing the piecewise sinusoidal function as the expansion and testing functions. Of particular interest, the effect of antenna length and shape of plate on the characteristics of monopole antenna is analyzed and the numerical results are presented.
