本文设计的天线采用圆盘上单极子结构,单极子天线结构为一种锥体和套筒组合体的形式,为了进一步拓展天线的带宽同时实现小型化要求,套筒顶部采用圆盘加载,锥体和圆盘之间采用短路加载,目的就是使天线在较小的尺寸情况下实现宽带指标。最终实现在806~960MHz/1710~2500MHz频带内满足指标要求。
The antenna designed in this paper adopts the monopole structure on the disk. The monopole antenna structure is in the form of a combination of a cone and a sleeve. In order to further expand the bandwidth of the antenna and achieve the miniaturization requirement, the top of the sleeve is loaded with a circular disk , Short circuit loading between cone and disc, the purpose is to make the antenna in the case of smaller size to achieve broadband indicators. The final realization of the 806 ~ 960MHz / 1710 ~ 2500MHz band to meet the target requirements.
