CPW‐FED omnidirectional hybrid microstrip/dielectric resonator antenna
Microwave and Optical Technology Letters, 2008AbstractIn this letter, we present a new antenna configuration in which a coplanar waveguide (CPW) is used to feed a cylindrical dielectric resonator (DR) and a subjacent circular patch to generate an omnidirectional radiation pattern. A first prototype, designed to resonate near 2.45 GHz, shows that an impedance bandwidth of 6.3% is achievable using a

Hybrid‐mode analysis of asymmetrical shielded dielectric resonator
Microwave and Optical Technology Letters, 1989AbstractA rigorous analysis is presented to determine the resonant frequency and Q factor of an asymmetrical resonator. The Galerkin method is used for the resonant frequency calculation, and the computation time is largely reduced by evaluating the integrals analytically.

A Broadband Hybrid Monopole-Dielectric Resonator Water Antenna
IEEE Antennas and Wireless Propagation Letters, 2017A broadband hybrid water antenna operating at very high frequency (VHF) band is presented, in which a simple seawater monopole is loaded with two distilled water cylinders working as dielectric resonators (DRs). By employing the loading technique, multiple close resonances are introduced to broaden the impedance bandwidth of the seawater antenna.

A new hybrid skirt monopole dielectric resonator antenna
2008 IEEE Antennas and Propagation Society International Symposium, 2008In this paper, a new hybrid dielectric resonator antenna has been proposed. A skirt monopole antenna is applied to excite an inverted-conical-shape DRA leading to improve the radiation performance of the antenna with respect to the recently presented structures.

Low profile wideband hybrid dielectric resonator and split ring resonator antenna
2011 IEEE International Symposium on Antennas and Propagation (APSURSI), 2011Two split ring resonators (SRRs) are fed by a very short T junction ended coaxial line and have a broadside radiation at low frequency. The ground backed dielectric substrate on which the SRRs are etched also functions as a dielectric resonator (DR) radiator at high frequency. Two DR modes are excited by the aid of the SRRs. With proper design, the SRR

New Hybrid Rectangular Dielectric Resonator Antenna with Enhanced Bandwidth
2020 IEEE International Symposium on Antennas and Propagation and North American Radio Science Meeting, 2020This paper introduces a simple and low-cost method to increase the bandwidth of a slot-fed rectangular dielectric resonator antenna. In this method, two parallel rectangular metallic strips are added to the two parallel flat sides of the DRA which are normal to the feeding slot.

Ultra wideband double-step hybrid rectangular dielectric resonator antenna
2013 IEEE Antennas and Propagation Society International Symposium (APSURSI), 2013In this paper, a novel ultra wideband compact size hybrid rectangular step dielectric resonator antenna (DRA) is proposed. The aim from the design process is to get an ultra wide impedance bandwidth with stable radiation pattern through the operating frequency. The entire simulation results have been obtained by using CST simulation software.
