Comprehensive Background of Antennas for Modern & State of Art Applications

Abstract

An antenna is well known device for all wireless communications, which include all types of telecommunications, Radars, Wi-Fi, RFID, IOT, Automobiles, TV and mobile communications. Without one type of antenna or the other, telecommunication does not exist. The types of antennas are many in number. Its size depends on frequency of operation, space requirements, type of application, desired polarization, type of radiation patterns, directivity, gain and VSWR requirements. The literature on antenna devices for communication and radar applications is sufficiently reported. However, the antennas used for RFID, IOT, Wi-Fi, Mobile handsets, Mobile towers and automobiles are not adequately reported in the open literature.

         In view of these facts, intensive studies are carried out to consolidate the background of antennas useful for the above applications. The work of this paper is highly useful for the antenna designers, users and analysts.
