Review of Design Strategies of Dual/Tri-Band Antennas for GPS and Irnss Applications

Abstract

In era of ever increasing demand of wireless communications, domain of antenna design has progressed rapidly and gained a lot of attention among researchers and academicians. Over past few decades, it has catered the needs of society and technocrats by proving itself as one of the main driving forces behind recent advancements in wireless communication. Especially in the GNSS applications, for civilian and military use, antenna design has played a vital role. Thus, a humble attempt is made in this article to provide a glance of globally used antenna for the GNSS applications. A spiral antenna. Various aspects of antenna characteristics have been described that gives insight of developments carried out in the field of spiral antenna design and important conclusions are drawn from the comparisons made for their future use. Comparative reviews between various aspects of antenna designs reveal the fact about promising performance of spiral based antenna in developing dual/tri band applications for GPS as well as IRNSS.
