摘要
本文用矩量法严格分析了考虑互耦影响时自适应天线阵元的电流分布,给出了计算电流的解析式,并计算了八单元圆阵的电流分布。用等效网络法推导了考虑互耦影响时的最佳权矢量。仿真计算了不同阵元间距时,自适应阵的数字波束赋形。
The distributing of current for adaptive antennas with the effect of mutual coupling with MoM is analysed rigorously. Analytical formula of current is presented and the distribution of current of circular array of eight ideal dipoles is calculated. Optimum weight vector taking into account the effect of mutual coupling is given by the method of equivalent network. The DBF of adaptive array in different element distance is simulated.
