A NOVEL COMPACT UWB NOTCH-FILTER ANTENNA WITH A DUAL-Y-SHAPED SLOT

Abstract

A novel compact planar antenna with a frequency band- fllter characteristic for UWB applications is proposed and investigated. Having a dual-Y-shaped slot on the patch, a frequency-notched characteristic at 5.2GHz is obtained. The band-notched mechanism of the designed antenna is implemented and experimentally studied. The designed antenna satisfles the voltage standing wave ratio (VSWR) requirement of less than 2.0 in the frequency band between 2.8 and 18.6GHz while showing the band rejection performance in the frequency band from 5.0 to 5.6GHz. This technique is suitable for creating ultra-wideband (UWB) antenna with narrow frequencynotched characteristics.
