Spiral Antennas for Communication Engineering Applications: A Systematic Approach

Abstract

The field of antenna's has progressed rapidly in the recent years it can certainly be considered as the main driving force behind the advancements being accomplished in the field of communications technology specifically wireless. This paper deals with the spiral antennas and their applications in various fields their properties which on further optimisation have lead to several inventions. The spiral antenna has several advantages over the other antenna's namely easy impedance matching, superior radiation efficiency, high spectral efficiency, consistent gain, high bandwidth aids in wireless communication and their major merit being they are frequency independent hence they find their application in various fields. The design optimisation is another main issue which largely determines the performance of an antenna similarly in spiral antenna also the variation in no of turns changing the width of its arm is helpful in producing best results. The following paper gives you the insight of developments done in the field of spiral antenna and the important conclusions which can be drawn from them for further use.
