He has contributed to or initiated various European research projects, e.g., more recently, the is3DMIMO, the WAVECOMBE 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, the 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 Radio, Propagation and Antenna Systems research. And he is also an Affiliate 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 a hundred scientific and technical publications. He is the co-author and co-editor of the textbook LTE-Advanced and Next Generation Wireless Networks – Channel Modelling and Propagation (Wiley, 2012).

Research profiles
I'm teaching and coordinating an MSc level course on MIMO systems, channels and antennas. The course gives some fundamental notions on MIMO channels, algorithms and performance metrics. MIMO antenna systems are a fundamental ingredient of 4G, 5G and Beyond 5G wireless systems.
I offer a variety of BSc and MSc thesis projects covering both theoretical and more practical aspects of antennas and propagation, related to antenna design, antenna characterization techniques, channel measurements, and modelling, as well as MIMO/Massive MIMO topics.

Current projects
WAVECOMBE - mmWave Communications in the Built Environments
This project has received funding from the European Union Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant agreement No. 766231 WAVECOMBE H2020-MSCA-ITN-2017.
The foreseen exponential growth of mobile data traffic will not be uniform across geographical areas but is mainly concentrated in hot spots that are usually located in the built environments (BEs) such as central business districts, stations, airports, stadiums, dense urban environments, etc. This poses considerable challenges that we believe can be solved by ultra-dense deployment of millimetre-wave (mmW) small-cells (SCs) in conjunction with massive multiple-input multiple-output (MIMO) in 5G and beyond 5G (B5G) wireless networks. However, there are a number of research challenges that need to be addressed for a successful deployment of 5G/B5G wireless networks: even if the theoretical background of massive MIMO is by now rather complete, the actual performance characterization and measurements of mmW antenna arrays have not yet been fully addressed at either the component or system level; mmW radio channel measurements have been performed but with limited time delay resolution, single antennas and over single radio links; and mmW bands have been considered for mobile communications, but the level of detail and diversity of BEs necessary for meaningful mmW SC deployment has not been fully exploited. Therefore, we propose here a research approach that combines the three disruptive key enabling technologies for 5G/B5G with the aim to answer fundamental questions that are still not well understood. Objectives: Develop and test mmW MIMO and massive MIMO antennas. Characterize and model radio propagation channel at mmW bands for typical BEs (offices, homes, stations, airports). Characterize and model the effect of the human body on MIMO radio propagation at mmW bands. Theoretically analyze and optimize massive MIMO mmW SC performance in the BEs. Jointly optimize the planning/deployment of massive MIMO mmW SC networks and their operating environments. Develop methods to retrofit existing buildings and to design new buildings for efficient high-capacity wireless communications in the BEs.
Indoor Small-Cell Networks with 3D MIMO Array Antennas (is3DMIMO)
This project has received funding from the European Union Horizon 2020 research and innovation program under the Marie Skłodowska-Curie grant agreement No. 734798 is3DMIMO H2020-MSCA-RISE-2016.
It is predicted that wireless network traffic will increase 1000 times in the next decade. The exponential traffic growth is not uniform across geographical areas and mainly takes place in indoor hot spots. Hence, high capacity indoor venues represent the biggest network capacity increase challenge. The recently emerged 3D MIMO technology provides a promising dimension to provide an extra capacity gain in hot spots. In particular, the 3D deployment of small cells (SCs) equipped with 3D MIMO antenna arrays will take advantage of the 3D distribution of user equipment (UE) in typical high capacity venues, and represents an excellent technical combination to address the indoor high capacity challenge. The 3D deployment of SCs with 3D MIMO antenna arrays faces technical challenges ranging from 3D MIMO antenna array design, performance evaluation, the lack of understanding of 3D MIMO SC network performance limits to the optimal 3D SC network deployment.
The OTA Project
Over-The-Air Characterization of Active Integrated Antennas for Mobile Systems
Through the past decades, the research area of antenna measurements (AMs) has undergone disruptive changes that have been stimulated by the development of novel wideband multiple-input multiple-output (MIMO) antenna systems and beamforming applications for wireless communications (e.g., 5G). The modern area of AM research can be referred to as Over-The-Air (OTA) characterization of antenna systems. OTA evaluates the impact of hardware, wave propagation, signal processing on the overall performance of the antenna system with regard to the most relevant parameters of wireless network performance. The key game changers and associated challenges that shape the OTA research come from the global shift towards massive multi-antenna systems (aka Massive MIMO), more advanced (hybrid analog-digital) signal processing, and much higher levels of integration between individual components (including active components too) and sub-systems. Performance testing of such advanced antenna systems requires sophisticated test methods and often new types of measurement tools. Moreover, until recently, testing of radio base stations could be performed conductively at a test port. This option is not sustainable for a large number of antenna ports and in fact, it is not even technically possible when going Massive MIMO at higher frequency bands, eg., at the mmWave frequency bands. OTA is therefore indispensable to characterize the performance of radio base stations at mmWaves but is also beneficial at lower frequencies too.
