Circularly Polarized Antennas

Abstract

This article is intended to present a comprehensive, technical review of circularly polarized (CP) antennas for an array of applications in various fields of wireless communication, emphasizing on the recent developments in the projected research. The article should also present a comparative study of various approaches reported in the open literature, with an aim to highlight the contribution of CP antenna systems and their chronological development in the domain of wireless communication technology. The primary motive of this literature is to (a) highlight the methodologies used by different attempts to portray and analyze the different aspects in which circularly polarized antennas find their applications in modern day wireless communication, (b) provide a practical viewpoint of the future scope of study, based upon the past and present state-of-art research trends, and (c) provide a conceptual and technical support to present day antenna designers to help the process of enhancement of innovation and multiple system integration.
