摘　　要：本文基于矩量法对采用中心单元激励的电抗加载圆形定向天线阵进行了较系统的理论与实验研究。首先建立了该阵的计算与优化程序 ,研究了只有一个中心有源单元的N元加载天线阵的特性与阵列参数的关系 ,并设计制作了一个 7元阵 ,对其输入阻抗、方向图及增益进行了实验测试。实验结果与计算值比较一致 。Based on the Moment Method (MM), a systemic theoretical and experimental study o n the reactively loaded directive circular array with a center element driven is presented. Its computation and optimization programs are established, and the r elationship between the performance and its parameters of an N element reac tively loaded circular array is given, then the design and experimental results of a seven element circular array is introduced. The measured results of input impedance, radiation patterns and gain of the array are in good agreement with t he computational values, verifying the validity of the analysis program and desi gn.
