Antenna Engineering : Theory and Problems

Antenna Theory and Problems of Antenna Engineering discusses methods of theoretical and experimental research and development of antennas. Controversial and vague points of thin antennas theory are reviewed and explained, new methods of analysis of the antennas'' electrical characteristics are described, and methods for solving synthesis problems are provided. New types of antennas, particularly flat and three-dimensional self-complementary antennas, are analyzed. The second part of the book is devoted to the description of specific kinds of antennas, including antennas for cell phones, ship antennas, and antennas for underground radio communications.

The book deals with theoretical and experimental research of antennas. The presentation is based on the electromagnetic theory. It begins with the theory of thin antennas. Thin antennas represent one of the main types of radiators, thus the theory of thin antennas is the basis of the antennas analysis.

Special attention is paid to the integral equation of Leontovich-Levin for a current along a straight thin-walled metal cylinder, which is equivalent to the equation of Hallen with a precise kernel. Together with the analysis of various types of antennas, the book deals with the problems of synthesis including the creation a wide-band radiator by means of determining of the types and the magnitudes of concentrated loads, which are connected along a linear radiator and create in a given frequency band high electrical performance.

Problems of antenna engineering are discussed in the second half of the book, including the results of application of a compensation method for the protection of humans against irradiation and structural features of ship antennas.
