共面馈电凹口矩形贴片天线间的互耦

Mutualcoupling in the notched rectangular patch antennas array fed by coplanar microstrip line

本文分析了共面馈电的凹口矩形微带贴片天线间的互耦模型,具体研究了天线介质包括厚度以及介电常数、不同阵元间距、不同的阵元放置方式、不同谐振长度的天线组合对于互耦的影响,确定了减小阵元间互耦的方法。互耦研究有利于大的阵面设计,并可以应用到空间多样性,极化多样性以及方向图多样性的天线阵设计中。

In this paper, the models of mutual coupling in the notched rectangular patch antenna array are analyzed, The effects on the mutual coupling in antenna array, including the dielectric, the distance between antenna elements, the orientation and resonant lengths of antenna elements, are respectively studied. The methods to reduce the mutual coupling are determined, The experimental results can help to design the large antenna array and also can be applied to the diversity antenna systems.
