【摘要】 本文对采用HIS结构降低天线阵列互耦效应进行了研究。设计了一种带枝节单叉形的小型化HIS结构,将其置于阵元间距为0.45个电波长的阵列天线单元之间,有效减小了相邻单元和非相邻单元之间的互耦。并将其应用于波束扫描线阵,改善了波束扫描时的阻抗匹配,特别是宽角度扫描时的驻波恶化现象,从而解决了扫描阵中扫描盲角的问题,增大了扫描阵的波束扫描范围。更多还原

【Abstract】 In this paper,the reduction of mutual coupling for antenna array using HIS has been investigated.A small-size single fork-like HIS is proposed and designed.Simulation results demonstrate that it can efficiently reduce the mutual coupling among antenna array elements,when placed between each adjacent elements with a distance of 0.45λ.Moreover,when employed in beam scanning array,the impedance matching can be significantly improved,especially when the scanning angle id wide,and thus causing larger scanning range.更多还原
