Microstrip and Cavity-Backed Antennas

Microstrip patch and cavity-backed antennas constitute an indispensable part of many devices [ 1,9—18]. Their notable properties and adjustable features lead to various efficient designs, which comprise the fundamental elements of many up-to-date configurations in telecommunication technology.
