基于透波增强的微波双频平板天线

内容简介：文章把微波段的透波增强理论应用于天线设计中，提出了一种新型的双频平板天线，该天线由两个亚波长环形孔周围环绕凹槽结构组成。天线在11.8GHz的工作频率点上的增益为8.33dB，在17.9GHz的工作频率点上的增益达到9.17dB。这种天线具有尺寸小、剖面低的特点，有着广阔的应用前景。

Abstract：In this article, the enhanced microwave transmission is applied in antenna design. A new dual-frequency planar antenna is proposed, which consists of two subwavelength annular apertures surrounded by a groove structure. The gain of the antenna is 8.33dB at 11.8GHz and 9.17dB at 17.9GHz. The antenna features small size, low profile, and has broad application prospect.
