Abstract

A novel triple-band notched circular ultrawideband (UWB) antenna with a band rejection characteristics at WiMAX, WLAN and C-band is presented. A design involving two concentric G-shaped circular slots etched on the circular patch structure and a U-shaped slot on the CPW transmission line is used to reject and control the notched frequency bands. The proposed antenna has good UWB characteristics from 3-12 GHz with VSWR <; 2, except frequency bands of 3.3-3.6 GHz, 3.7-4.2 GHz, and 5.1-5.9 GHz. The designed structure exhibits good radiation characteristics over the desired band and is a good candidate for UWB applications.

超宽带应用的三带陷波圆单极天线设计

提出了一种具有WiMAX、WLAN和c波段抑制特性的新型三频带陷波圆超宽带(UWB)天线。采用在圆形贴片结构上刻蚀两个同心g形圆槽和在CPW传输线上刻蚀一个u形槽的设计来抑制和控制陷波频带。该天线在3 ~ 12 GHz范围内具有良好的超宽带特性，驻波比<;3.3 ~ 3.6 GHz、3.7 ~ 4.2 GHz、5.1 ~ 5.9 GHz频段除外。所设计的结构在期望的波段上具有良好的辐射特性，是超宽带应用的良好候选者。
