Assessment of the implications of the radiowave propagation environment for the design of antennas and wireless communication systems. Development of computer-aided instrumentation, and data mining and scientific visualization techniques in support of the above. Our Mission Contribute to the theory and practice of wireless communications system design with particular emphasis on propagation and channel modelling and development of low-profile antennas. Support Canadian industry, government, and academia by addressing research problems of direct and immediate interest to them, often under the aegis of collaborative research agreements. Train, through both research and course work, highly qualified personnel (HQP) in wireless communications systems design who will meet the staffing needs of Canadian industry, government, and academia. Serve both the university and the community through participation in committees, editorial boards, and related bodies. Background and Motivation Propagation impairments constrain our ability to achieve the desired coverage, capacity, and quality of service at a reasonable cost. Radiowave propagation and channel models translate our knowledge and understanding of the wireless environment into a form useful in system analysis, design, and deployment. As wireless networks become more complex, move to higher frequencies, and/or are deployed in more challenging situations, propagation and channel models which accurately describe the new environments must be developed.   News and Announcements    14 Sep 2009 - Welcome to Wang Huan, a visiting PhD student from Harbin Engineering University in China, who will be working in our lab for the next year.

Prof. Dave Michelson - Group Leader David G. Michelson received the BASc, MASc, and PhD, all in Electrical Engineering, from the University of British Columbia, Vancouver, BC, Canada.      From 1994-1996, Dr. Michelson was a postdoctoral research fellow in the MacDonald Dettwiler/NSERC Radar Remote Sensing Group at UBC where he studied electromagnetic scattering from terrain, applications of polarimetric radar data, and the application of synthetic aperture radar data to RF coverage prediction.      From 1996-2001, he served as a member of a joint AT&T Wireless Services (Redmond, WA) and AT&T Labs – Research (Red Bank, NJ) team concerned with development of propagation and channel models for next generation and fixed wireless systems.  The results of this work formed the basis for the propagation and channel models later adopted by the IEEE 802.16 Working Group on Broadband Fixed Wireless Access Standards.      From 2001-2002, he helped to oversee deployment of one of the world’s largest campus wireless LANs at the University of British Columbia while also serving as an adjunct professor in the Department of Electrical and Computer Engineering. In 2003, he became a full-time faculty member at UBC where he now leads the Radio Science Lab. His current research interests include propagation and channel modeling and low profile antenna design.      Professor Michelson is a senior member of IEEE and a member of the Applied Computational Electromagnetics Society. He serves as Chair of the IEEE VT-S Technical Committee on Propagation and Channel Modeling and as an Associate Editor for propagation and channel modeling for IEEE Transactions on Vehicular Technology. In 2002, he served as a guest editor for a pair of special issues of IEEE Journal on Selected Areas in Communications concerning propagation and channel modelling.  He chairs the IEEE Vancouver Section’s Joint Communications Chapter which represents the IEEE Communications Society, Antennas and Propagation Society, and Vehicular Technology Society. Under his leadership, the Chapter received an Outstanding Achievement Award from ComSoc in 2002.
