摘要

提出了一种提高孔径耦合微带贴片天线增益的新方法。该方法利用了一个介电罩，该介电罩与天线隔开一定高度。通过适当选择这个高度，我们证明了模拟增益的增加超过7dB。这不会影响匹配带宽，但会影响增益带宽和辐射波束宽度。

Investigations on an aperture-coupled microstrip patch antenna with a spaced dielectric cover for enhanced gain performance

A novel method for increasing the gain of an aperture-coupled microstrip patch antenna is presented. The method makes use of a dielectric cover that is spaced some height off of the antenna. By proper choice of this height, we demonstrate an increase in simulated gain of more than 7dB. This comes at no cost to the matching bandwidth, but affects the gain bandwidth and radiation beamwidth.
