Klaus Solbach was born in Witten, Germany in 1951 and received the Dipl.-Ing. degree from the
RWTH Aachen in 1974 and the Dr.-Ing. degree from the University of Duisburg in 1979. From 1975 to 1980 he has been employed at the University of Duisburg as a Researcher in the field of integrated dielectric image line circuits in the millimeter wave frequency range. In 1981 he joined the Millimeter wave Research Laboratory at AEG-Telefunken in Ulm, where he designed receive/transmit circuits and antennas for millimeter wave radar and communications equipment. After changing to the Radar Systems Group of Daimler-Benz Aerospace (now part of Airbus Defence and Space), in 1984 he engaged in the design and production of microwave subsystems for ground based and airborne Radar, EW and communication systems including phased array and active phased array antenna systems. His last position was manager of the RF and-Antenna-Subsystems Department.
In 1997 he joined the faculty of the University of Duisburg as chair for RF and Microwave Technology. After serving as Vice-Dean of the Department of Electrical Engineering and Dean of the newly founded Faculty of Engineering he next served as Vice-Rector of the newly merged University Duisburg-Essen until end of 2006. He was chairman of the VDE-ITG Fachausschuss “Antennen”, executive secretary of the “Institut für Mikrowellen- und Antennentechnik (IMA)” and Chair of the IEEE German AP/MTT Joint Chapter. He has been a member of the editorial board of the IEEE Transactions on Microwave Theory and Techniques and member of a number of technical program committees of national and European scientific conferences. In 2007 he was General Chair of the international “ITG-Conference on Antennas INICA2007” in Munich and in 2009 he was General Chair of the “European Conference on Antennas and Propagation(EuCAP)” in Berlin, Germany. He has authored and co-authored more than 200 national and international papers, conference contributions, book chapters and patent applications.
After official retirement at the age of 65, in August 2016 he joined the department of Digital Signal Processing (DSV) directed by Prof. Thomas Kaiser as a Senior Professor for RF Technology.
