In this letter, a stacked triangular prism shaped dielectric resonator antenna (DRA) is proposed for ultrawideband (UWB) applications. A combination of three techniques namely, stacking of DRAs, introduction of triangular shaped conformal patch loop excited by coaxial feed, and fractal geometries are utilized on triangular prism shaped DRA to achieve UWB. Improvement in bandwidth (BW) is achieved by introduction of triangular shaped fractal slots and by sandwiching low permittivity DR material is sandwiched between two high permittivity DR materials. Finally, by introduction of triangular loop shaped conformal patch, UWB is achieved. The proposed antenna is fabricated and measured impedance BW of about 120.9% covering frequency range from 3.3 to 13.4 GHz (C‐ and X‐band) is achieved. 98.8% radiation efficiency and average gain of 7 dBi has been achieved over the entire frequency band of interest. Discussions on various design parameters and its associated results are included in this letter.

“…Consequently, special DRA shapes and multi-segment DRAs have been reviewed extensively. Rectangular [17], Conical [18], asymmetrical E [19], Stair-Shaped [20], Inverted L-shaped [21], elliptical [22], asymmetrical T-shaped [23], tetrahedral [24] with triangular slot [25], ring-shaped [4] cylindrical [2], [26]- [28], and hybrid hemispherical-conicalshaped [29] configurations have all been suggested for antenna bandwidth enhancement. Gain and bandwidth enhancement configurations were presented in [2] and [30], where two cylindrical dielectric resonators were asymmetrically placed around the center of the rectangular coupling aperture, and fed through this defected ground plane aperture.…”

A new compact Cylindrical Dielectric Resonator Antenna (CDRA) with a defected ground for ultra-wideband applications is presented. The structure is based on two cylindrical dielectric resonators asymmetrically located with respect to the center of an offset rectangular coupling aperture, with consideration of three and four Dielectric Resonators (DR). The resonant modes generated by the defected ground are studied and investigated. A parametric optimization study of the antenna design has been carried out to determine the optimal dimensions of the defected ground plane, resulting in an impedance bandwidth of over 133% that covers the frequency band from 3.6 GHz to 18.0 GHz. A power gain of about 7.9 dBi has been achieved. Design details and measured and simulated results are presented and discussed. INDEX TERMS Cylindrical dielectric resonators antenna, ultra-wideband, defected ground structure.

Abstract-Design and analysis of a novel wide-band covering, hetero triangle linked hybrid web fractal antenna is presented in this paper. The hetero triangle linked hybrid web structure has been designed through multiple iterations in the CST MICROWAVE STUDIO electromagnetic simulation tool and has been fabricated on FR4 dielectric of ε r = 4.4 with height of 1.6 mm. The proposed antenna offers a comprehensive bandwidth of 18.055 GHz, covering from 1.945 GHz to 20 GHz. It supports various applications starting from 3G, LTE, ISM, Bluetooth, Wi-Fi, WLAN (2.4-2.48 GHz) and 5.2/5.8 GHz (5.15-5.35 GHz/5.72-5.82 GHz), WiMAX operating in the 2.3/2.5 GHz (2.305-2.36 GHz/2.5-2.69 GHz), 5.5 GHz (5.25-5.85 GHz) and Satellite communication (Ku band: Uplink of 14 GHz and Downlink of 10.9-12.75 GHz). The proposed antenna provides peak realized gain of 7.17 dB with efficiency more than 78% in the operating band. The antenna parameters such as reflection coefficient, gain and radiation patterns are determined through numerical simulation, and good matching is obtained with measured results.
