An antenna is an array of conductors that serves as the interface between radio waves and the electrical currents in metal conductors. It is essential for both transmitters and radio receivers, enabling the transfer of electrical signals to and from the electromagnetic field. Radio waves, which are a type of electromagnetic wave, propagate at the speed of light through air without significant transmission loss. Antennas can be classified based on their operating principles or applications, with common types including omnidirectional and directional antennas, as well as specific designs such as whip and dipole antennas. Both antennas and wave propagation are fundamental to the operation of any radio system. Wave propagation refers to the study of how waves travel, and radio propagation specifically focuses on the behavior of radio waves as they move from one point to another. This book elucidates the concepts and innovative models around prospective developments with respect to antennas and wave propagation. The topics included herein are of utmost significance and bound to provide incredible insights to readers. It will provide comprehensive knowledge to the readers.
