“…The modeling and simulations of the antenna have been performed using HFSS tool. Compared to the recently obtained impedance bandwidth of 138% of the double stacked conical DRA [3], the proposed three stacked conical DRA can provide an improved impedance bandwidth of 161% with an enhancement of 23% bandwidth.…”

“…For this purpose many bandwidth enhancement techniques of dielectric resonator antenna have been investigated [3]- [9]. A quarter wavelength monopole antenna is loaded by a cylindrical dielectric ring resonator (CDRR) [6], double annular ring resonator [4], conical ring resonator with a band-notch function [7].…”

“…Then after a CDRR with stepped radius has been investigated with an impedance bandwidth of 110% [5]. Recently stacked conical ring DRA excited by a monopole for improved impedance bandwidth of 138% has been reported [3].In these above designs the monopole antenna behaves as a radiator as well as a feed to the DRA simultaneously. The DRA is excited in TM ଵஔ mode which radiates like an electric monopole with an omnidirectional radiation pattern.…”

In order to maneuver over the ultra wideband range, several structures have been investigated with increased impedance bandwidth. In this context a three stacked conical ring dielectric resonator antenna has been proposed to operate beyond the ultra wideband range. The proposed antenna offers a fractional bandwidth of 161% with a monopole type radiation pattern. The enhanced bandwidth is due to the resonance of the monopole antenna at about its each wavelength for which the stacked conical resonators are highly indispensable.

“…They can maintain high radiation efficiency, even at millimeter-wave frequencies due to low surface wave losses and minimal conductor losses. Moreover, the remarkable broad and ultra wideband (UWB) features offered by DRAs make them as potential candidates for UWB systems [2][3][4][5][6][7][8][9]. The intensive investigations on UWB DRAs have been pursued and published.…”

“…The intensive investigations on UWB DRAs have been pursued and published. Using hybrid configurations, several monopole-DRAs have been studied, which are constructed by a vertical monopole antenna loaded with a ring-shaped dielectric resonator (DR) around in the horizontal plane [4][5][6][7][8]. Recently, a combination of broadband planar monopole and a rectangular DRA has been reported, which has a bandwidth from 3.06 to 10.6 GHz [9].…”

Abstract-An ultra-wideband (UWB) planar monopole antenna integrated with a narrow-band (NB) cylindrical dielectric resonator antenna (DRA) is presented. The proposed antenna consists of a UWB monopole excited by a coplanar waveguide (CPW) transmission line, acting as a ground for a DRA excited by a slot. The mode HEM 11δ is excited in the NB DRA. To validate the concept of integration, an antenna is fabricated and measured. The measured results demonstrate that the UWB antenna provides a 2 : 1 voltage standing wave ratio (VSWR) bandwidth for 3.05-11 GHz, integrated with a dual-band NB antenna. Moreover, the two ports have the same polarization and a reasonable isolation (less than −10 dB) between each other. This is a promising candidate for applications in cognitive radio, where the UWB antenna can be used for spectrum sensing and the NB antenna for communication operation.

This article shows a compressed chronological overview of dielectric resonator antennas (DRAs) emphasizing the developments targeting to bandwidth performance characteristics in last three and half decades. The research articles available in open literature give strong information about the innovation and rapid developments of DRAs since 1980s. The sole intention of this review article is to, (a) highlight the novel researchers and to analyze their effective and innovative research carried out on DRA for the furtherance of its performance in terms of only bandwidth and bandwidth with other characteristics, (b) give a practical prediction of future of DRA as per the past and current state-of-art condition, and (c) provide a conceptual support to the antenna modelers for further innovations as well as miniaturization of the existing ones. In addition some of the significant observations made during the review can be noted as follows; (a) hybrid shape DRAs with Sierpinski and Minkowski fractal DRAs seems comfortable in obtaining wideband as well as multiband, (b) combination of multiple resonant modes (preferably lower modes) can lead to wider impedance bandwidth, (c) at proper matching wider patch with slotted dielectric resonator can exhibit better bandwidth.
