可调频率三频单极子手机天线研究

摘要

In this paper, a novel minitype tri-band monopole antenna which is used inside the handset is proposed and analyzed. The propose antenna has a PEC branch through which the second work band of the antenna can be adjusted. A larger dimension in wavelength is implemented in a small area by bending the antenna in three-dimensional space. The antenna is simple structure and convenient in designe. It can be a promising inside antenna for handsets.%设计和初步讨论了一种小型化工作频率可调的三频手机天线。天线设置了一个频率调节枝节，通过该枝节可方便调整第二工作频率，以达到用户特殊需求。此外，天线利用空间折叠方法在较小空间内实现了较大的电尺寸（天线主体尺寸为19．4ram＊10mm＊5mm），天线结构简单、设计方便，实用性强。
