摘　　要：采用矩量法对对数周期偶极天线扇形阵进行理论分析 ,在计算广义阻抗矩阵元素时 ,利用矩阵的互易性、天线阵的结构对称性和对数周期天线的工作原理进行了算法简化 ,从而在保证计算精度的前提下 。In this paper, the electrical characteristics of a fan-shaped array of log-periodic dipole antennas is analyzed by using the method of moments. Employing the array symmetries and the reciprocity characteristics of the general matrix, and considering the principle of a log-periodic dipole antenna, the computation time and necessary storage space are effectively reduced when the elements of the general matrix are calculated.
