摘要
本文设计了一种加载介质打孔覆盖层的宽带高增益天线。由平面宽带磁电偶极子天线,空气层及上层加载结构构成,天线工作在Ku频段。将不加载介质打孔覆盖层的天线辐射特性与加载介质打孔覆盖层后的天线进行比较。结果显示,介质打孔覆盖层进一步提升了天线的方向性和增益,使其可以更好的应用于卫星通信等无线通信领域。
a broadband high-gain antenna with medium perforated cover is designed. It consists of a planar broadband magnetic dipole antenna, an air layer and an upper loading structure, and operates in the Ku band. The antenna radiation characteristics of the media perforated cover layer are compared with the antenna after loading the media perforation overlay. The results show that the dielectric perforation layer further enhances the directionality and gain of the antenna. So that it can be better applied to satellite communications and other wireless communications.
