T-Strip-fed high-permittivity rectangular dielectric resonator antenna for broadband applications

Abstract

A rectangular low-density high-permittivity dielectric resonator antenna (DRA) excited by T-shaped microstrip feed offering a 2:1 VSWR bandwidth of similar to 22% at 2.975 GHz is reported. The design methodology, and experimental results of the antenna are discussed. The excellent gain and radiation performance of the proposed antenna projects it as a potential candidate for telecommunication applications.
