Compact wideband perforated Rectangular Dielectric Resonator Antenna

2015 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2015
A compact Rectangular Dielectric Resonator Antenna is designed using perforations (symmetrical array of square slots) and edge grounding. The perforations improve impedance bandwidth by lowering down the quality factor. The perforations are selected in such a manner that fundamental TE 111 mode is preserved in the modified perforated structure.

New wideband quadrature rectangular dielectric resonator antenna

2015 European Microwave Conference (EuMC), 2015
New wideband quadrature rectangular dielectric resonator antenna is designed and proposed. The square shaped slots are drilled to obtain wide impedance bandwidth by reduction of effective dielectric constant. Metallization is incorporated along the edges to make the structure compact by removal of dielectric in the direction of symmetry plane of ...

A CPW-fed rectangular dielectric resonator antenna

APMC 2001. 2001 Asia-Pacific Microwave Conference (Cat. No.01TH8577), 2002
A CPW-fed rectangular dielectric resonator antenna is presented. The reflection coefficient and radiation patterns of such a dielectric resonator antenna with a high dielectric constant fed by an open-ended coplanar waveguide are studied. In the antenna design, the offset distance from the center of the dielectric resonator antenna to the open-ended ...

Broadband Circularly Polarized Rectangular Dielectric Resonant Antenna

2019 Cross Strait Quad-Regional Radio Science and Wireless Technology Conference (CSQRWC), 2019
This paper proposed a circularly polarized rectangular dielectric resonant antenna (RDRA) fed by a strip-line. A relatively high dielectric constant radiating element is placed centrally on the ground plane, and a circularly polarized (CP) field is generated by the excitation of the strip-line which is orthogonally placed on the side wall of the RDRA ...

Printed Slot Wideband Rectangular Dielectric Resonator Antenna

2020
In this paper, a high performance wideband dielectric resonator antenna is investigated. It is observed that wide bandwidth and multi-band operations can be realized with a hybrid structure by amalgamating wide slot patch antenna and dielectric resonator antenna which are resonating at nearby frequencies.

TLM analysis of rectangular dielectric resonator antennas

IEEE Antennas and Propagation Society International Symposium. 1995 Digest, 2002
The authors report the analysis of aperture-coupled and microstrip proximity-coupled dielectric resonator antennas (DRAs). The TLM numerical method was combined with a linear circuit simulator to determine the input impedance of DRAs for optimum feed dimensions. The numerical results agree well with experimental data.

Gain enhanced omnidirectional rectangular dielectric resonator antenna

2015 IEEE International Conference on Computational Electromagnetics, 2015
The omnidirectional rectangular dielectric resonator (DR) antenna (DRA) using its higher-order quasi-TM 015 mode is proposed for the gain enhancement. It was designed, fabricated and measured for 5.8-GHz WLAN applications. Its measured bandwidth and antenna gain of the proposed DRA are 4.84% and 3.63 dBi, respectively.

Dimensional analysis of the rectangular dielectric resonator

IEEE Antennas and Propagation Society International Symposium. Digest. Held in conjunction with: USNC/CNC/URSI North American Radio Sci. Meeting (Cat. No.03CH37450), 2004
Dimensional analysis is used to study the resonant frequency of the rectangular dielectric resonator (DR). The function is then found by using a curve-fitting technique. The result is accurate for 97 /spl ges/ /spl epsiv/ /sub r2/ /spl ges/10, 1/spl ges/ b/a /spl ges/0.2 and 0.86/spl ges/ d/a /spl ges/0.16, where a, b and c are the dimensions of the DR.
