| With the increased demand for wireless communication systems and satellite communications providing a integral part of this communication demand, there is a requirement to develop antenna systems that are efficient and dependable. Dielectric Resonator Antennas (DRA) are capable of meeting these demands in a more compact manner than traditional metallic antenna structures. One requirement for those who design satellite communication systems is to develop antennas that utilize Circular Polarization (CP), which reduce losses associated with environmental conditions that can change the orientation of an electromagentic signal being transmitted between satellites and Earth-based antenna systems. The Comb-Shaped Dielectric Resonator Antenna (CS-DRA) studied during the course of this thesis work proves to be a simple and compact DRA design that can meet this demand. The CS-DRA has been designed to operate at frequencies above 1 gigahertz, with a focus at the Global Positioning Systems level 1 frequency. The CS-DRA's design provides a very wide CP beamwidth from the boresite, which means large coverage area. As well, due to the material chosen for the CS-DRA it will be dependable across a wide range of temperatures and resistant to moisture and mildew buildup, which can hinder the performance of metallic antennas over time.;Keywords: Dielectric Resonator Antenna, DRA, Circular Polarization, GPS, Scalability. |
