A Comparative Study of Different Feeding Mechanisms for Rectangular Dielectric Resonator Antenna

Abstract

The paper describes the performance analysis of different feeding mechanisms for Rectangular Dielectric Resonator Antenna (RDRA). Due to the variety of feeding mechanisms available to antenna designers such as microstrip line fed, coaxial probe fed, Co-Planar Waveguide (CPW) fed and slot/aperture couple fed, a proper practice to select the best possible feeding mechanism is required. In this paper, an RDRA is used to investigate the performance of different feeding mechanisms-based antenna systems. These feeding techniques give a better understanding of design parameters of an antenna and their effect on return losses, bandwidth, VSWR and resonant frequency.
