Design and Analysis of Circular Dielectric Resonator Antenna for High Speed Communication Systems

Abstract

Along with infrastructure like roads, water supply, transportation, communication holds a newlineprominent position in the development and growth of civilization. Advancements in newlineinformation technology, media and social networks have been possible largely due to high newlinespeed communication systems working round the clock seamlessly. Through mobile and newlinesatellite technology, today it is possible to communicate over any arbitrary distance at any point newlineof time. newlineGrowth of communication technology has given birth to similar advancements in the design newlineand development of high speed antennas which are the backbone of any communication newlineinfrastructure and have made long distance communication possible using electromagnetic newlinefields. However, despite several technological innovations, design of antenna has remained newlineprimarily an ad-hoc exercise as a consequence of which antenna design and it s time to market newlinedeadline has been quite challenging. newlineIn this Thesis, efforts have been made to reduce the challenges by developing a new newlinemathematical framework for designing Dielectric Resonator Antenna (DRA) of any arbitrary newlineshape and size. The mathematical framework has been developed to yield numerical values of newlinethe solution of Maxwell s equations both for near field and far field antenna configurations newlinewhich are necessary for a communication design engineer for accurate estimation and design newlineof the antenna for a given specification. newlineIt is a known fact ever since it was realized that electromagnetic fields can be used for long newlinerange communication that obtaining closed form solutions of Maxwell s equations for arbitrary newlinefield and geometric configurations is a highly challenging task. Hence, it was necessary since newlinea long time that a consistent mathematical framework is realized that can provide numerical newlinesolutions of the complex Maxwell s equations without compromising on the accuracy. newline
