Reconfigurable Antennas for 5G Wireless Communication Systems: Vision and Challenges
Nowadays, reconfigurable antennas using advanced technologies are one of the advanced research topics, which have received much interest from many research and industrial groups worldwide. Using advanced design approaches, new reconfigurable antennas can be developed and used us an enabling technology to improve the performance of future 5G wireless communication systems. These approaches are based on using advanced materials, including electromagnetic band gap (EBG) structures, and frequency selective surfaces (FSS). The objective is to design and implement new compact, low profile, and low cost reconfigurable antennas with high performances in terms of beam-forming ability, high gain and efficiency. With these features, they can be used to improve the performances of future 5G wireless communication systems. For instance, they allow saving energy, increasing the coverage area, and reducing interference, which lead to good transmission quality. In this talk, I will first give a brief introduction on the 5G wireless communication systems, presenting their potentials and challenges. Second, I will give an overview on electromagnetic band gap structures and their applications in advanced antenna designs. Third, I will present a few configurations of reconfigurable antennas using various electromagnetic band gap structures. To show the radiation-pattern configurability of these antennas, some examples of simulated and experimental results will be presented and discussed. Finally, concluding remarks will be given.
Tayeb A. DENIDNI (M’98–SM’04) received M. Sc. and Ph.D. degrees in electrical engineering from Laval University, Quebec City, QC, Canada, in 1990 and 1994, respectively. From 1994 to 2000, he was a Professor with the engineering department, Université du Quebec in Rimouski (UQAR), Rimouski, QC, Canada, where he founded the Telecommunications laboratory. Since August 2000, he has been with the Institut National de la Recherche Scientifique (INRS), Université du Quebec, Montreal, QC, Canada. He found RF laboratory at INRS-EM, Montreal. He has a great experience with antenna design and he is leading a large research group consisting of three research scientists, six Ph. D students, and one M.Sc. student. He served as a principal investigator on many research project sponsored By NSERC, FCI and numerous industries. His current research areas of interest include reconfigurable antennas using EBG and FSS structures, dielectric resonator antennas, metamaterial antennas, adaptive arrays, switched multi-beam antenna arrays, ultra-wideband antennas, microwave and development for wireless communications systems.
