Antennas

The book comprises a new method of solving the integral equation of Leontovich, the most rigorous and most effective equation for the current in thin linear antennas. The book describes the features of the new method in its application in various types of antennas. It considers new ways of analyzing antennas, in particular in the calculation of an antenna gain based on main radiation patterns and the calculation of the directional characteristics of radiators with known distribution of current amplitude. The method of electrostatic analogy proposed by the author, provides the base for comparison of electromagnetic fields of high-frequency currents and electrostatic charges located on linear conductors to improve the directional characteristics of log-periodic and director-type antennas. A new approach to the analysis of the electrical characteristics of a microstrip antenna, which allows expansion of its operation range, is substantiated and developed. New results of antenna synthesis are obtained. The second part of the book is devoted to specific types of antennas (the author had a significant role in their creation). Particular attention is given to ship antennas for different frequency ranges. The book is intended for professionals, working in electrodynamics and those working on development, placement and exploitation of antennas. It will be useful for lecturers (university-level professors), teachers, students of radio engineering and researchers working in various fields of radio electronics and interested in an in-depth study of theoretical problems and designs f antennas. It can also be used for short university courses.

Boris Levin was born in Saratov, Russia, in January 1937. He graduated from Leningrad Polytechnic Institute in 1960, received his Ph.D. in radio physics from Central Research Institute of Automatic Devices in Leningrad in 1969 and Degree of Doctor of Sciences in Physics and Mathematics (Russian equivalent of professor degree) from S.-Petersburg Polytechnic University in 1993. From 1963 to 1998 he worked for the Design Department "Svyazmorproyekt" of Russia Shipbuilding Ministry. In Israel he worked in Holon Institute of Technology, Israel. Now he is retired. Levin Boris has authored eight books, including three books in Russian and five books in English: "The theory of thin antennas and its use in antenna engineering" (Bentham Science Publishers, 2013), "Method of complex potential in antenna engineering" (LAP, 2014), "Inverse problems of antennas theory" (LAP, 2014), "Antenna engineering. Theory and problems" (CRC Press, 2017), and "Wide-range and multi-frequency antennas" (CRC Press, 2019). Besides he has authored 89 original articles in technical journals, 91 papers in proceedings of international scientific conferences, and 45 patents. His main research interests are in the fields of the electromagnetic theory, the theory of linear antennas and antenna optimization. Major accomplishments are analysis, design and developments of new antennas.
