摘要
提出了一种新的互耦补偿方法并应用到偶极子天线阵,该方法采用初次特征基函数作为每个阵元在阵列环境中的电流分布,分别应用互易定理和感应电动势法计算互阻抗矩阵,有效地修正了传统开路电压模型中的不足,具有明显高于传统方法的补偿精度;同时对近年提出的一种新互阻抗定义作了理论推导,证明了该方法与本文方法是等效的,而作者所宣称的新互阻抗定义并没有脱离传统框架.
A mutual coupling compensation method is proposed and applied in the dipole array. The mutual impedance is calculated by the reciprocity formulation and EMF method respectively base on the current distribution obtained by the characteristic basis function method. Significant compensation performance can be obtained compared to conventional open-circuit model. Also a new definition of mutual impedance proposed recently is investigated theoretically. It is shown that this method is equivalent to our approach, which is derived from conventional method.
