| 摘 要： | 设计了具有宽频带特性的双层结构3单元直线阵微带天线。综合采用双层结构和阻抗匹配网络两种方法来展宽天线的频带,天线在驻波比小于1.6时的相对带宽达13.3%。采用边缘微带线馈电方式,降低了天线纵向结构尺寸;上层贴片悬置,更有利于天线的封装和维护。设计在满足天线宽频带要求和结构简单可靠两方面取得了较好的平衡。

| Abstract: | A broadband linear antenna array with 3 two-layer radiation elements is designed in this paper.Two techniques,i.e.two-layer structure and impedance matching network,are adopted to enhance the bandwidth,as a result,the input impedance bandwidth is up to 13.3% for VSWR<1.6.In order to reduce the thickness of the product,edge feed microstrip line instead of couple feed is used.Placing the upper patch under its substrate has the advantage of easier encapsulation and maintenance.This design is a comparison between the requirement of wide band and simple structure. |
