DESIGN AND ANALYSIS OF DIELECTRIC RESONATOR ANTENNAS (DRA) USING NUMERICAL METHODS: A COMPREHENSIVE SURVEY

  • Thangadurai N

Abstract

This paper provides an in-depth analysis of noteworthy research performed over more than two decades on dielectric resonator (DR) antenna modelling by utilizing the numerical methods. Due to its captivating features namely small size, low loss, high performance, large bandwidth, three-dimensional design versatility compared to traditional antennas, etc., the dielectric resonator antenna (DRA) has produced its individual life in antenna engineering. Nowadays, DR antennas are generally designed by applying the numerical techniques. The primary goal of this review article is to give an overview of DRA designing with the help of single as well as the hybrid numerical methods. Another objective is to provide a compressive review of noteworthy numerical designing studies conducted on DRAs and last but not the least aim is to provide some favourable future concentration for antenna scientists in order to apply numerical techniques to some ground breaking DRA geometries.
