Recently, wearable wireless devices have been widely used in our daily life. Also, implantable wireless devices have been developed and become available for various monitoring as well as identification systems. Unlike conventional wireless devices, wearable or implantable devices are used on or in the human body. In this sense, body-centric wireless communications (BCWCs) have become a very active area of research. On the other hand, radio-frequency or microwave medical devices used for cancer treatment and surgical operation have completely different functions. However, they are used on or in the human body. In terms of antennas installed inside the devices, such medical devices have lots of similarities to BCWCs. To design properly and to make the best use of specific antennas for different wireless devices, it is important to treat them as human-centric antennas.  In general, the problem of an antenna placed on or in the human body can be treated as a so-called “boundary value problem” where the human body is considered as a lossy medium. However, in reality and simplicity, an individual case is treated appropriately in a specific manner by numerical simulation such as the FDTD technique.

The presentation introduces a few examples of wearable antennas as well as implantable antennas which have been developed and tested in our laboratory. In addition, the presentation describes some challenges of human-centric antennas.



Koichi Ito received the B.S. and M.S. degrees from Chiba University, Japan, and the Ph.D degree from Tokyo Institute of Technology, Japan.  He is currently a Professor Emeritus and Visiting Professor at the Center for Frontier Medical Engineering, Chiba University.  From 2005 to 2009, he was Deputy Vice-President for Research, Chiba University.  From 2009 to 2015, he served as Director of the Center for Frontier Medical Engineering, Chiba University. 

His main research interests include small antennas for mobile communications, microwave antennas for medical applications such as cancer treatment, research on evaluation of the interaction between electromagnetic fields and the human body by use of phantoms, and antenna systems for body-centric wireless communications. 

Professor Ito is a Life Fellow of the IEEE, a Fellow of the Institute of Electronics, Information and Communication Engineers, Japan (IEICE).  He served as Chair of the Technical Committee on Human Phantoms for Electromagnetics, IEICE, from 1998 to 2006, Chair of the Technical Committee on Antennas and Propagation, IEICE, from 2009 to 2011, Chair of the IEEE AP-S Japan Chapter from 2001 to 2002, General Chair of the 2008 IEEE International Workshop on Antenna Technology (iWAT2008), an AdCom member for the IEEE AP-S from 2007 to 2009, an Associate Editor for the IEEE Transactions on Antennas and Propagation from 2004 to 2010, a Distinguished Lecturer for the IEEE AP-S from 2007 to 2011, General Chair of the 2012 International Symposium on Antennas and Propagation (ISAP2012), and a member of the Board of Directors, Bioelectromagnetics Society (BEMS), from 2010 to 2013.  He has been elected as a delegate to the European Association on Antennas and Propagation (EurAAP) since 2012 and Chair of Commission K, Japan National Committee of URSI (International Union of Radio Science) since 2014.  He currently serves as a Councilor to the Asian Society of Hyperthermic Oncology (ASHO) and an Associate Editor for the IEEE J-ERM (Journal of Electromagnetics, RF and Microwave in Medicine and Biology).
