Dielectric Resonator Antennas : theory and design

Abstract

Theoretical models for the analysis of Dielectric Resonator Antenna (DRA) are developed. There are no exact solutions to many of the problems in analytical form, therefore a strong focus on the physical interpretation of the numerical results is presented alongside theoretical models. I have used the physical interpretation of the numerical results to lay down some important design rules. A few new inventions associated with the DRA are also included. These are the elliptical DRA, the DRA with a rectangular slot, the adjustable reactance feed, the triangular DRA and the dual band DRA-patch antenna.
