摘　　要：运用小波分析与矩量法相结合的方法来求解线天线的电流积分方程。首先阐述了矩量法用于分析线天线的一般概念和基本思想,然后采用小波矩量法对偶极子天线的电流积分方程进行快速求解,并与传统矩量法分析进行比较。仿真结果表明,该方法能够使传统矩量法中的阻抗矩阵大大地稀疏化,从而达到了提高求解速度和节省计算机内存的目的。Current distribution of wire antennas is studied in this paper using wavelet method of moment.Firstly,the concept and the basic idea of wire antennas analysis are discussed using moment method.Then,the current integral equation of dipole antenna is solved fast using wavelet method of moment which is compared with the traditional moment method.The simulation result shows that the wavelet method of moment can make the impedance matrix sparseness.Thus,the solving speed is significantly accelerated and computer memory is saved.
