| 摘 要： | 利用矩量法对宽带圆形阵列天线的互耦特性进行分析。为了对较粗线天线进行精确分析,矩量法采用正弦差值基函数与点配法,并采用全域线天线积分核计算Pocklington方程,得到天线的广义散射矩阵,实现互耦分析。为了验证其计算结果,对所设计阵列天线进行了CST软件仿真和实验测试。仿真和测试结果表明：矩量法计算与CST仿真结果基本相同,实验测试结果在主波束方向、主波瓣宽度、副瓣电平等特性上与计算和仿真结果近似一致,说明此方法能够有效的对宽带阵列天线进行互耦分析。

| Abstract: | This paper analyzes the mutual coupling of broadband circular array antenna with MOM.In order to get an accurate analysis of thick wire antennas,MOM uses sinusoidal basis functions and point matching method and then applies full cylindrical wire kernel to calculate the Pocklington equation.With this method,the generalized scattering matrix will be got,and the analysis of mutual coupling could be attained.In the paper,CST and experimental tests have been employed to inspect the calculation results: the resul... |
