The book provides a broad coverage of antenna types and phenomena, for operations at very low radio frequencies, as well as frequencies up to those of submillimeter wavelengths. Unlike most university-level antenna textbooks, it does not require prior skills in electromagnetic theory, sophisticated mathematics, or computer programming.
3.1 BASIC ANTENNA PROPERTIES. Most antennas reversibly link radiation fields to currents flowing in wires at frequencies ranging from sub-audio through the far-infrared region. Aperture antennas that link radiation fields to materials can operate in microwave, infrared, visible, ultraviolet, X-ray, gamma ray, and even higher energy regimes.
This book attempts to deal with the basic concepts relevant to receiving and transmitting antennas in a manner which emphasises the mechanisms involved and minimises the mathematics used. The bibliography provided offers the next stage of reading and understanding, while the outline set of original papers
In this chapter, you are going to learn the basic concepts of antenna, specifications and different types of antennas. Need of Antenna In the field of communication systems, whenever the need for wireless communication arises, there occurs the necessity of an antenna.
