Now in an completely revised, updated, and enlarged Second Edition, Small Antennas in Portable Devices reviews recent significant theoretical and practical developments in the electrically small antenna area. Examining antenna designs that work as well as those that have limitations, this new edition provides practicing engineers and upper level and graduate students with new information on: work on improving bandwidth using spherical helix dipoles; work on electromagnetically coupled structures; exact derivation of the Q for electrically small antennas for both the TE and TM modes; and a new simplified Q formula.

Über den Autor:

Robert C. Hansen, PhD, DEng, has had a long and distinguished career in the aerospace industry. Beginning in 1949, he held key posts in a number of leading aerospace companies, including The Aerospace Corp., STL, Inc. (now TRW), and Hughes Aircraft Co. He is a Fellow of IEEE and IEE and is a member of the National Academy of Engineering. Since 1971, Dr. Hansen has been a consulting engineer for antennas and systems-related problems. The Late Robert Collin, PhD, taught at Case Reserve Western University, where he was chairman of the Department of Electrical Engineering and Applied Physics. He was an invited professor at Pontifical Catholic University of Rio de Janeiro; Telebras Research Center, Brazil; and Beijing University, China. Dr. Collin was the author or coauthor of five books and more than 150 technical papers.
