摘要:

针对移动通信终端小型化、集成化的发展趋势,本文提出一种中心频率为7.3 GHz 的小尺寸宽频带天线。基于微带天线理论及单极天线的典型结构,改变三维结构、平面形状及介质的宽度,设计出一种新型的小型天线。考虑到影响天线特性的相关因素,利用HFSS11软件进行仿真优化,结果表明,该天线大小仅为16 mm×17 mm,绝对带宽可达3.2 GHz(S11<-10 dB),远远超过了500 MHz,为一宽带小型天线。

关键词: 单极天线, 三维结构, HFSS11, 宽带

Abstract:

In consideration of the miniaturization and integration of development tendency for mobile communications terminations,this paper presents an antennas with miniaturiation and wide-band.Based on theory about microstrip and typical structure of monopole antennas,the antennas is designed that can change the three-dimensional structure into a plane structure and the length of the dielectric slab.The experiments show that the antennas is a kind of wide-band antennas with size 16 mm× 17 mm and an absolute frequency bandwith for 3.2 GHz(S11<-10 dB).

Key words: monopole antenna, three-dimensional structure, HFSS11, wide bandwidth
