摘要
通过对天线电流分布和辐射特性的分析,本文提出了一种基于PCB多层板工艺技术的新型微带栅格天线,该天线利用PCB过孔技术,将天线网格进行弯折,牺牲了部分厚度特性,使得天线投影面积减小,实现了微带栅格天线的小型化。通过CST仿真软件对其性能进行了的仿真分析,与经典的微带栅格天线相比,其尺寸减小了27%、带宽增加了180%、天线匹配更容易实现。
The new type of wire grid antenna which is based on multilayered printed circuit board is designed and introduced.Plated through hole is used to bend wire grid of this antenna.The antenna is miniaturized as thickness of the PC B increased.Parasitic patches are added to optimize the structure of the antenna.Comparing with classical wire grid antenna, the antenna has an advantage in size, bandwidth as well as matching characteristic.The features of the antenna are analyzed by C ST.The greater properties are confirmed.
