摘要

本文研究了一种工作在基模下的矩形波导馈电平面喇叭天线。本研究的目的是利用周期性叠加的亚波长空穴阵列来提高增益。我们应用了几种不同厚度的金属板和不同距离的周期性堆叠亚波长孔阵列。我们发现在某些情况下,增益从6到17.5dB有很好的提高。结果表明,在横向共振情况下,天线的指向性良好。

Planar horn antenna: Application of periodic stacked subwavelength hole array with metamaterials proprieties
In this paper, we study a planar horn antenna fed by a rectangular waveguide operating in the fundamental mode. The aim of this work is to enhance gain by periodic stacked subwavelengh hole array. We applied several types of holes with different thicknesses of the metal plate and with varied distance between the periodic stacked subwavelength hole array and the antenna. We found a good improvement of gain from 6 to 17.5dB in some cases. We also showed that the directivity of the antenna is good in the case of transverse resonance.
