The need that arose during the war for utilizing the microwave region of the radio frequency spectrum for communications and radar stimulated the development of new types of antennas. The problems and design techniques, lying as they do in the domain of both applied electromagnetic theory and optics, are quite distinct from those of long-wave antennas. It is the aim of the present volume to make available to the antenna engineer a systematic treatment of the basic principles and the fundamental microwave antenna types and techniques. The elements of electromagnetic theory and physical optics that are needed as a basis for design techniques are developed quite fully. Critical attention is paid to the assumptions and approximations that are commonly made in the theoretical developments to emphasize the domain of applicability of the results. The subject of geometrical optics has been treated only to the extent necessary to formulate its basic principles and to show its relation as a short wavelength approximation to the more exact methods of field theory.
