Design of Rectangular Dielectric Resonator Antenna for Artificial Neural Network

This paper represents a study of simulation of a Dielectric Resonator Antenna (DRA) based on its rectangular shape for Artificial Neural Network (ANN). The DRA is intended to be used as the radiating element of a transmitting array of active integrated antennas; its input impedance must exhibit a proper resistive load at the fundamental resonance frequency, as well as a dominant reactive behavi...

Wideband Rectangular Dielectric Resonator Antenna (dra) with Slot-fed Design

A novel wideband rectangular dielectric resonator antenna (DRA) is proposed in this paper. A hybrid structure with an isolated dielectric resonator (DR) and an equivalent air-dielectric DR is introduced by lifting the resonator from the ground plane. The hybrid structure is excited by a slot-fed mechanism to obtain a smooth transition between each resonant mode. The resonant modes of the isolat...

New Dielectric Resonator Antenna Design for Mobile Handsets

A new design of Dielectric Resonator Antenna (DRA) for mobile handsets is presented: the off-centre ring dielectric resonator antenna (OCRDRA). This achieved 15.9% impedance bandwidth (for S11 < -10 dB) by using high dielectric constant material (εr = 77) with coaxial probe feed. The geometry of the antenna is small, having key dimensions of the order of λo/10. Different inner diameters were te...

Design of Rectangular Dielectric Resonator Antenna Fed by Dielectric Image Line with a Finite Ground Plane

A Rectangular Dielectric Resonator Antenna (RDRA) fed by Dielectric Image Line (DIL) through a narrow slot placed on a finite ground plane is numerically investigated. The effects of ground plane size on the radiation performance of the antenna are analyzed. To increase the antenna gain, four sidewalls are placed around the corners of the ground. Also, a reflector is placed at the back side of ...
