Description
Now in a newly updated and revised edition, this timely resource provides you with complete and current details on the theory, design, and applications of wireless antennas for on-body electronic systems. The Second Edition offers readers brand new material on advances in physical phantom design and production, recent developments in simulation methods and numerical phantoms, descriptions of methods for simulation of moving bodies, and the use of the body as a transmission channel. You also find a completely revised chapter on channel characterization and antenna design at microwave frequencies. This cutting-edge volume brings you the state-of-the-art in existing applications like Bluetooth headsets together with detailed treatment of techniques, tools, and challenges in developing on-body antennas for an array of medical, emergency response, law enforcement, personal entertainment, and military applications on the horizon. The book briefs you on energy propagation around and into the body and how to estimate performance of on-body wireless links, and then dives into the nuts-and-bolts of designing antenna systems that deliver the goods. It covers on-body communication channels at microwave frequency bands and at low frequency bands, as well as ultra wideband systems for WPANs and WBANs. You get details on body-centric UWB antennas and channels, as well as advances in wearable mobile, EBG, and smart fabricù antennas for cellular and WLAN communications. Chapters on telemedicine applications, such as remote diagnoses, and implantable medical devices cover crucial propagation issues and other obstacles that need to be addressed. Rounding out the coverage is a section on antenna design for body-sensor networks and their emerging military and space applications. Packed with hands-on guidance from noted experts, this volume will be indispensable for your efforts in designing and improving body-centric communication systems.

Yang Hao
Yang Hao is Professor of Antennas and Electromagnetics at Queen Mary University of London (QMUL). Over the years, he has developed several fully-integrated antenna solutions based on novel artificial materials to reduce mutual RF interference, weight, cost and system complexity for security, aerospace and healthcare applications. He coined the term 'Body-centric wireless communications', an area which refers to networking among wearable and implantable wireless sensors on the human body. He contributed to the industrial development of wireless sensors for healthcare monitoring as well as wearable and textile antennas. He currently leads several major developments in microwave metamaterials, body-centric wireless communications and is also a member of management team at the Cambridge Graphene Centre. Professor Hao has published 2 books, 7 book chapters and more than 120 journal papers. From 2010-2012, he served as a Vice Chairman for the Professional Network on Antenna and Propagations, IET and is also a board member of European School of Antennas, European Antenna Centre of Excellence. He is an associate editor for both IEEE TAP and AWPL. In 2013, Professor Hao received the prestigious Wolfson Research Merit Award from the Royal Society, UK. He is a Fellow of IEEE, IET and ERA Foundation.
