基于共面波导馈电的三频单极子天线
Tri-Band Monopole Antenna Based on CPW-Feed
摘要
Abstract
In this paper,a novel compact monopole antenna fed by a coplanar waveguide (CPW)for tri-band applications is presented.It comprises two different monopoles and can operate at three resonant frequencies of 1.57 GHz,2.4 GHz and 3.5 GHz.The resonant frequency 1.57 GHz and 3.5 GHz are controlled mainly by the longer monopole and 2.4 GHz is mainly decided by the shorter monopole.In order to improve the gain of the antenna,a rectangular patch is added on the left side of the ground plane.The realized antenna has a total size of 59 mm×40.55 mm×1.6 mm.The bandwidth at three frequencies are 254 MHz (1.518 GHz~1.772 GHz),461 MHz (2.289 GHz~2.75 GHz)and 226 MHz (3.514 GHz~3.714 GHz)respectively,covering the band for GPS,WLAN and wireless ac-cess system.The gains are 2.15 dBi,3.12 dBi and 3.86 dBi respectively.关键词
