Optical dielectric resonator antenna
2012 9th International Conference on Communications (COMM), 2012In this paper we propose that a dielectric dot on the top of a ground plane could act as an antenna in optical frequency range. We investigate its electromagnetic properties numerically and observe that its behaviors are similar to dielectric resonator antenna in radio frequency.

Circularly Polarized MIMO Dielectric Resonator Antenna With Reduced Mutual Coupling
IEEE Transactions on Antennas and Propagation, 2021A circularly polarized (CP) multiple-input–multiple-output (MIMO) antenna is investigated. This MIMO antenna consists of two identical dielectric resonator antennas (DRAs), which use the same feeding cross slots to generate the same CP fields. Four metal

The influence of the dielectric constant in dielectric resonator antennas
2016 International Conference on Communications (COMM), 2016This paper presents a comparison between dielectric resonator antennas with different dielectric constant parameter of the resonator. The antenna is fed with microstrip line. The dielectric resonators have cylindrical geometry. In HFSS software program, the simulations are up to compare the antennas' behavior as a function of different parameters, such

A Dental Dielectric Resonator Antenna
2024 IEEE International Symposium on Antennas and Propagation and INC/USNC‐URSI Radio Science Meeting (AP-S/INC-USNC-URSI)In this paper, a dental dielectric resonator antenna (DRA) is proposed. The implantable dental DRA is proved feasible by using real extracted human tooth as the dielectric resonator (DR).

A Wideband Dielectric Resonator Antenna
2025 19th European Conference on Antennas and Propagation (EuCAP)This paper presents a wideband dielectric resonator antenna (DRA) with three excited modes: the fundamental TEll1 mode and the higher-order TEll3 and $\text{TE}_{212}$ modes, which are merged to achieve a wide impedance bandwidth.

Design of Filtering Dielectric Resonator Antenna Arrays Using Simple Feeding Networks
IEEE Transactions on Antennas and Propagation, 2022A 1 $\times $ 3 filtering dielectric resonator antenna (DRA) array is investigated in this communication. The central DRA is excited by a microstrip-coupled slot, while the two side DRA elements are, respectively, excited by the central DRA via a low ...

2015 Conference on Microwave Techniques (COMITE), 2015
This article is focused on using a dielectric resonator as a radiating element of a antenna with the aim to reduce dimensions of such antennas compared to classical microstrip antennas. Such antenna was build and its parameters tested in frequency band of 2.9 to 3.1 GHz.
