摘要

本文研究了一种基于模式的方法，可以从紧密耦合的天线中获得最大增益。由于偶极子天线之间的距离很小，因此天线增益有可能超过物理孔径限制，因此称为超增益。传统的超增益天线实际上只是超指向性，因为在这些系统中存在严重的阻抗失匹配，指向性不能转化为实际的天线增益。

A mode-based supergain approach with closely coupled monopole pair

This paper focuses on a mode-based approach that can obtain the maximum gain from closely coupled antennas. Because of the small separation between the coupled dipole antennas, the antenna gain can potentially surpass the physical aperture limit and thus be called supergain. Traditional supergain antennas are actually superdirective only as the directivity can not be translated into real antenna gain because of severe impedance mismatching in those systems.
