Electronically Polarization-Reconfigurable Rectangular Dielectric Resonator Antenna

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
A reconfigurable rectangular dielectric resonator antenna (DRA) using modified cross-slot feed to obtain switchable polarization is proposed. The proposed antenna employs electronically changing the lengths of slots to generate and alter left/right handed circular polarizations and vertical linear polarizations, respectively. By designing the structure

A wideband‐stacked rectangular dielectric resonator antenna

Microwave and Optical Technology Letters, 2010
AbstractA stacked rectangular dielectric resonator antenna (DRA) is studied experimentally. The achieved impedance bandwidth of two DR stacked antenna is about 73%. By stacking two different permittivity DRs, the multi‐band of single element DRA is changed to single wideband giving out improvement in bandwidth.

3D-printed Wideband Rectangular Dielectric Resonator Antenna

2019 Photonics & Electromagnetics Research Symposium - Fall (PIERS - Fall), 2019
A 3D-printed wideband rectangular dielectric resonator antenna (DRA) with omnidirectional radiation patterns is investigated. It is a multilayered design with four concentric square dielectric rings, which have progressively decreased effective dielectric constants in the azimuthal direction. To facilitate the 3D printing, a unit cubic cell that can be

Wide-band rectangular dielectric resonator antenna design

2010 IEEE Asia-Pacific Conference on Applied Electromagnetics (APACE), 2010
In this paper a novel design procedure to obtain wideband and small size dielectric antennas using high dielectric constant material is described. It is shown that by selecting the resonator shape and creating a notch on the dielectric resonator, it is possible to design rectangular dielectric resonator antenna which compact size and wide frequency ...

Rectangular dielectric resonator antenna for RFID application

2nd European Conference on Antennas and Propagation (EuCAP 2007), 2007
The use of rectangular dielectric resonator antenna (RDRA) suitable for 2.45 GHz microwave RFID application on metallic platforms is investigated. Simulated and measured return losses for the RDRA are presented. The read range performance of a backscatter RFID tag, using the RDRA with horizontal polarization, is investigated in cluttered and ...

A low-profile rectangular dielectric-resonator antenna

IEEE Transactions on Antennas and Propagation, 1996
A rectangular dielectric-resonator antenna (DRA) with a very low profile (length-to-height ratio /spl ap/6) is presented. This aperture-coupled antenna is almost perfectly matched to the 50 /spl Omega/ input and radiates like a magnetic dipole at 11.6 GHz.
