Talk 1: Experimental RF and antenna research—past and future (Prof. Gert F. Pedersen, Aalborg University, Denmark)
Since the first mobile terminals and phones entered the market, many works on their actual coverage in the network have been carried out and troubles with the coverage reported. Now we have 5G advanced systems and the coverage is surely much better, but is the problem of good coverage everywhere solved? The talk will give a historical overview of the development of the methods used for evaluating the ability of a mobile phone to provide good coverage, including the vast experimental setups used and concluding with the Over The Air (OTA) measurements used worldwide today. Results of OTA performance evaluation of mobile phones done over the years for the Danish authorities will be shown, including the latest report listing the most popular phone models from spring 2023. Also the latest experimental setup in Aalborg will be shown — a large anechoic room which can take objects up to 3500 kg and measure all frequencies from around 100 MHz to THz. Examples of large constructions which can be measured are given; Wind turbine blades, live fighter jets and surely cars.
Talk 2: Handset and Base Station Antennas for Mobile Communications: Past, Present, and Future (Prof. Shuai Zhang, Aalborg University, Denmark)
This presentation traces their development from the basic designs to the transformative innovations. The introduction of MIMO handset antennas in 4G enabled higher data rates, while 5G brought mmWave handset antennas and massive MIMO base station arrays to meet the demands of ultra-fast, low-latency networks. Looking forward, 6G will push the boundaries further with ultra-large massive MIMO antenna arrays, promising extreme capacity and seamless global connectivity with its near-field and far-field properties. The discussion will also touch on related advances in bio-electromagnetics, metasurfaces, and the role of antennas in emerging fields such as drones and satellites, emphasizing their critical role in shaping the future of wireless mobile communication.
Bio:
Gert Frølund Pedersen was born December 2nd 1965 in Denmark. He received the B.Sc. E. E. degree, with honours, in electrical engineering from the College of Technology, Dublin, Ireland in 1991, and the M.Sc. E. E. degree and Ph. D. from Aalborg University, Denmark in 1993 and 2003. He has been employed by Aalborg University since 1993 where he is now a full Professor, heading the Antenna, Propagation and Millimetre-wave Systems section with more than 30 full-time researchers.
His research has focused on radio communication for mobile terminals including small antennas, antenna systems, radio propagation and biological effects. He started the area of Over The Air (OTA) test for small active terminals including the antenna and developed the measuring setup, now used worldwide. He invented the integrated antenna in 1994 for mobile phones, used in most mobile phones today. He has worked closely with both national and international companies and designed more than 100 unique antenna solutions. He is currently involved in antenna systems for small devices, Satellites and 6G.
His research merits include PI funding of more than 75 M€ mainly jointly with industry, and has published over 300 journal papers, 400 conference papers and holds more than 50 granted patents.
Shuai Zhang (Fellow, IEEE) received the B.E. degree from the University of Electronic Science and Technology of China, Chengdu, China, in 2007, and the Ph.D. degree in electromagnetic engineering from the Royal Institute of Technology (KTH), Stockholm, Sweden, in 2013. In 2014, he joined Aalborg University, Denmark, where he is currently a Full Professor and the Head of Antenna Research Group. In 2010 and 2011, he was a Visiting Researcher with Lund University, Sweden, and Sony Mobile Communications AB, Sweden, respectively. He was also an External Antenna Specialist with Bang & Olufsen, Denmark, from 2016 to 2017. He has coauthored over 140 articles in well-reputed international journals and over 17 (US or WO) patents. His current research interests include mmwave antennas for cellular communications, biological effects, metasurfaces, CubeSat antennas, massive MIMO antenna arrays, wireless sensors, and RFID antennas.
