Antenna Systems for 6G Mobile Communication Aim at Providing Ubiquitous Connectivity in a So Called “Cyber-Physical World”


Related applications require e.g. a merge of sensing systems (e.g. radar) and communication systems. Such Joint Communication and Sensing (JCaS) will be used e.g. for road traffic control but is also discussed to improve safety in the so-called low-level airspace and the corridor of urban air mobility (UAM) which is foreseen to be densely populated e.g. by drones in the future. JCaS comes along with new challenges as traditionally radar and communication system are developed with different demands. They result in different requirements for the radio system in general and for the antennas in particular, - such as high isolation of the antenna ports in an array. The first part of the talk will address design concepts of antennas with intrinsic high port isolation and will discuss how these elements can be used in multi-beam beamforming antenna arrays for 6G. In addition, inter element antenna coupling and sub-array coupling in antenna arrays is addressed and modelling strategies for optimization are proposed. Metasurfaces play an important role in 6G antenna and infrastructure design. They are used in reconfigurable intelligent surfaces (RIS) to tailor the propagation environment, they can act as meta-lenses to focus and redirect antenna beams and they can be used to construct a modulated metasurface antenna aperture with desired electromagnetic behavior. Metasurfaces consist of a periodic lattice of unit cells and the electromagnetic behavior is bound to both the unit cell design and the periodicity of the lattice. While there exist dedicated design methods based on the periodicity the specific unit cell design is typically just chosen from a catalog of standard structures with known properties. Therefore, the second part of the talk will focus on educated design of unit cells in a periodic environment. It is demonstrated how unit cell behavior can be modelled in a periodic lattice and how modal decompositions can help to understand and purposefully design unit cells for metasurfaces.





Dirk Manteuffel was born in Issum, Germany, in 1970. He received the Dipl.- Ing. and Dr.-Ing. degrees in electrical engineering from the University of Duisburg-Essen, Duisburg, Germany, in 1998 and 2002, respectively. From 1998 to 2009, he was with IMST, Kamp-Lintfort, Germany. As a Project Manager, he was responsible for industrial antenna development and advanced projects in the field of antennas and electromagnetic (EM) modeling. From 2009 to 2016, he was a Full Professor of wireless communications with Christian-Albrechts-University, Kiel, Germany. Since June 2016, he has been a Full Professor and the Executive Director of the Institute of Microwave and Wireless Systems, Leibniz University Hannover, Hannover, Germany. His research interests include electromagnetics, antenna integration, and EM modeling for mobile communications and biomedical applications. Dr. Manteuffel was the Director of the European Association on Antennas and Propagation from 2012 to 2015. He served on the Administrative Committee (AdCom) of the IEEE Antennas and Propagation Society from 2013 to 2015. From 2014 to 2022 he served as an Associate Editor of the IEEE Transactions on Antennas and Propagation. Since 2005 he has been a Director of the European School on Antennas (ESoA) and organized several courses on Industrial Antennas Design and Characteristic Modes. Since 2009, he has been an appointed member of the Committee “Antennas” of the German VDE-ITG.
