Band-notched UWB rectangular dielectric resonator antenna

Abstract

A new ultra-wideband (UWB) rectangular dielectric resonator antenna (DRA) with band-stop performance is proposed. Two symmetrical short-circuited strips together with a slot etched in the feeding patch are introduced to form the notched band. The design principles of the proposed methods are described in detail. The measured result demonstrates that the proposed DRA achieves an UWB bandwidth from 3.6 to 12 GHz for a voltage standing wave ratio <2 with a notched band from 5.1 to 6.0 GHz.
