Modal Analysis and Mode Excitation of Multilayer Hemispherical Dielectric Resonator Antennas using an Efficient Computation Technique

Abstract

This dissertation has been devoted to the rigorous modal analysis of multilayer HDRA excited by four different feeds namely the microstrip-slot feed, the waveguide slot feed, the coaxial probe feed, and the conformal strip feed. The analysis is carried out using the Green’s function and the Method of Moments ( MoM ) approach. The theoretical results have been verified by experiments.
