This newly revised and expanded edition of the Artech House classic, Radiowave Propagation and Antennas for Personal Communications, offers you a current and comprehensive introduction to the practice and underpinnings of personal communications. Every chapter has been updated to explain how the latest ultra-wide band technology affects all aspects of personal communications. The third edition covers important innovations such as wireless local networks, personal networks, and MIMO techniques. This practical resource emphasizes three distinct but interrelated problems: fixed site antennas, radiowave propagation, and small antennas used close to the human body. Giving you the systems level view of design and analysis, the book helps you solve propagation problems in large-scale urban settings, in-building settings, and in the personal area space. In addition to its accessible coverage of technology and theory, this unique volume examines how radio waves and wireless devices affect the human body.
