摘　　要：针对传统矩量法分析电大目标难度大的问题,近几年提出一种有效的方法——特征基函数法。文中采用此方法结合空域格林函数法对一些微带天线阵列的电磁特性进行了研究,其中研究并运用磁流圆盘来模拟同轴激励源,运用简化附加模模型模拟线面连接处的电流。数值分析结果与MOM、软件仿真、相关文献的结果吻合良好,与MOM相比计算时间大大减少,从而证明了此方法的正确性、通用性和优越性。Considering the difficulty in analyzing the electromagnetic characteristic of electrically large objects using the MOM,CBFM as an effective way of solving the electromagnetic problems is proposed recently.In this paper,the electromagnetic characteristic of microstrip antenna arrays has been analyzed using the CBFM and space Green function method.Magnetic frill mode was studied and applied to simulate the coaxial excitation source.One attachment mode was applied to simulate current at the junction.The numerical results are in good agreement with those achieved by the MOM,some commercial electromagnetic softwares or other papers,while the computation time is reduced considerably,which confirms the correctness,universality and superiority of this method.
