This article presents an inclusive review of notable research carried out on modelling of dielectric resonator (DR)-antenna using numerical methods in last more than two decades. Dielectric resonator antenna (DRA) has created its individual existence in antenna engineering because of its captivating characteristics like; small size, low loss, high efficiency, wide bandwidth, three-dimensional design flexibility as compared to conventional antennas, etc. The DR antennas are being widely modelled using numerical methods nowadays. The triple-folded intention of this review article is to: (1) give an overview on DRA modelling using single and hybrid numerical methods, (2) give a compressive review of notable numerical modelling researches carried out on DRAs and (3) give some favourable future concentration for the antenna researchers in order to apply the numerical methods on some innovative geometries of DRAs.
