Get ready for the tidal wave of "body centric" electronic systems that will take mobile communications and computing to new heights! This first-of-its-kind book will help engineers pave the way with its definitive treatment of on-body antenna theory, design and applications. It covers both the state-of-the-art in existing systems together with new advances leading to medical, personal entertainment, law enforcement, and military applications now in development. This cutting-edge resource briefs engineers on key propagation issues and then dives into the nuts-and-bolts of antenna design that delivers the goods. It covers on-body communication channels at microwave frequency and low frequency bands, as well as ultra wideband systems for WPANs (wireless personal area networks) and WBANs (wireless body area networks).
