A UWB Probe-Fed Dielectric Resonator Antenna

VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009
This paper presents a stacked rectangular dielectric resonator antenna for ultra-wideband applications. The antenna is composed of a dielectric resonator and a thin dielectric segment, and is excited by a coaxial probe. Theoretical results show that an ultra-wide band, from 3.1 GHz to 10.7 GHz, can be achieved.

Optimization of Dielectric Resonator Antennas

2014
In this chapter we demonstrate the use of SBO methodology for design optimization of dielectric resonator antennas (DRAs). Analysis, design verification, and optimization of DRAs are all simulation based because analytical models of DRA (Petosa 2007), though indispensable, can be used mostly to estimate initial designs which should be further tuned to ...

Resonant frequency of dielectric ring resonator antenna

1992 Symposium on Antenna Technology and Applied Electromagnetics, 1992
A dielectric resonator (DR) placed in an open environment radiates strongly at and around its resonant frequencies. Among the advantages of DR antennas are their small size and no conductor loss. The other features of DR antennas are that each mode has a unique radiation pattern and the frequency bandwidth over which the antenna radiates efficiently ...

Dielectric resonator antennas and applications

IEE Seminar Integrated and Miniaturised Antenna Technologies for Asset Tracking Applications, 2000
Dielectric resonator antennas (DRAs) are usually made of dielectric resonators with ɛr ranging from 10 to 100. The resonance mode used for radiation depends on the geometry of the resonator and the required radiation patterns. The fields of the mode need not to be strongly confined within the resonator, so that it can be easily fed to produce high ...

Reconfigurable Dielectric Resonator Antennas

2011
With the increasing demand for high performance communication networks and the proliferation of mobile devices, significant advances in antenna design are essential. In recent years the rising demands of the mobile wireless communication industry have forced antennas to have increased performance while being limited to an ever decreasing footprint ...
