ANTENNA SYSTEMS, PROPAGATION CHANNELS, OTA CHARACTERIZATION OF WIRELESS DEVICES AND WIRELESS PERFORMANCE OF BUILDINGS

Share

Antenna systems and propagation are at the core of the development of new wireless technologies, especially for 5G, 6G and beyond wireless networks and applications. Fundamentally, the propagation channel need to be studied in order to design and optimize wireless system performance. Of special relevance is the polarimetric spatio-temporal behavior of the transfer functions between transmit and receive multi-port antennas at different frequency band from MHz to THz. The overall wireless system performance requirements dictates the desired antenna system characteristics, e.g., bandwidth, EIRP, beams scanning, etc. And therefore, also the choice of antenna system technologies for a specific application is influenced by the propagation channel, e.g., frequency band and spatial distribution of users. Hence, the need for the proper modelling of the interactions between the antennas and the propagation channel. In 5G systems and beyond, multiple antenna systems known as massive MIMO play a fundamental role to serve many users with high data bitrates simultaneously over a wide spectrum known as spatial division multiplexing. Antenna systems are integrated into wireless devices of all types (e.g., base stations, smart phones, laptops, vehicles of all type, etc.) and need to be characterized in the research and development stage, also in type approval and conformance testing as well as in the production line. As we are going towards 6G applications, not only small or massive antenna systems deployed in various devices need to be developed, but new ways of enhancing the propagation channel need to be devised. For example, metamaterials and other structures that can be used to facilitate the propagation of electromagnetic waves in desired directions is of great relevance. Therefore, the impact of different solutions need to understood as well as the development of performance characterization methods, especially for the indoor environment.

In this talk I will present results and ongoing research related to phased arrays based on the Gap Waveguide (GW) and Magneto-Electric Dipole (MED) technology, antenna-channel interactions in terms of the spherical vector wave (SVW) expansion of the electromagnetic field, over-the-air (OTA) characterization of wireless devices for cellular and automotive applications, e.g., the Random Line-Of-Sight (Random LOS) and the Hybrid Anechoic & Reverberation Chamber (HARC) as well as the concept of Building Wireless Performance (BWP).

Biography:

Andres Alayon Glazunov (SM’11) was born in Havana, Cuba. He received the M.Sc. (Engineer-Researcher) degree in physical engineering from Peter the Great St. Petersburg Polytechnic University (Polytech), St. Petersburg, Russia, in 1994, the Ph.D. degree in electrical engineering from Lund University, Lund Sweden, in 2009, and the Docent (Habilitation) qualification in antenna systems from Chalmers University of Technology, Gothenburg, Sweden, in 2017. From 1996-2005, he held various research and specialist positions in the Telecom industry, e.g., Ericsson Research, Telia Research, and TeliaSonera, in Stockholm, Sweden. From 2001-2005, he was the Swedish delegate to the European Cost Action 273  and from 2018-2020 he was the Dutch delegate to the European Cost Action IRACON. He has been one of the pioneers in producing the first standardized OTA measurement techniques for 3GPP, and devising novel OTA techniques, e.g., the Random-LOS and the Hybrid antenna characterization techiques.

He has contributed to, or initiated various European research projects, e.g., more recently, the is3DMIMO, the WAVECOMBE, the 5VC and the Build-Wise projects under the auspices of the H2020 European Research and Innovation program. Dr. Glazunov has also contributed to the international 3GPP and the ITU standardization bodies. From 2009-2010, he held a Marie Curie Senior Research Fellowship at the Centre for Wireless Network Design, University of Bedfordshire, Luton, U.K. From 2010-2014, he held a post-doctoral position with the Electromagnetic Engineering Laboratory, KTH-Royal Institute of Technology, Stockholm, Sweden. From 2014-2018, he held an Assistant Professor position at Chalmers University of Technology, Gothenburg, Sweden.

Dr. Glazunov is currently an Associate Professor with the Department of Electrical Engineering, University of Twente, Enschede, the Netherlands, where he is leading the Antenna Systems, Propagation and OTA research. And he is also an Affiliate Associate Professor with the Chalmers University of Technology, Gothenburg, Sweden, where he is leading the OTA Characterization of Antenna Systems research area. He is the author of more than hundred and fifty scientific and technical publications. He is the co-author and co-editor of the text book LTE-Advanced and Next Generation Wireless Networks – Channel Modelling and Propagation (Wiley, 2012). His current research interests include, but are not limited to mmWave array antenna design, MIMO antenna systems, electromagnetic theory, fundamental limitations on antenna-channel interactions, radio propagation channel measurements, modeling and simulations, wireless performance in the built environment, and the OTA characterization of antenna systems and wireless devices.
