A small UWB antenna with triple band-notched characteristics

Abstract

A small CPW fed triple band-notched (Ultra Wide Band) UWB antenna is presented. The proposed antenna consists of a shovel-shaped radiating patch with three C-shaped slots, a feed line and a modified ground plane. By etching three C-shaped slots with variable dimensions on the radiating patch, frequency band-stop performance is generated and we can control its band-notched frequency and bandwidth through modifying the dimensions of C-shaped slot. The proposed antenna has a very compact size of 14×22×1.6mm3. Simulated VSWR shows that the proposed antenna could operate from 2.88 to 10.67 GHz with VSWR less than 2, except 3.20 to 3.97GHz, 5.26 to 5.75GHz and 7.57 to 8.37 GHz.
