Research profile
Ulf Johannsen is an Assistant Professor with the Electromagnetics group at the TU/e department of Electrical Engineering. His research focus is on (sub-)millimeter-wave antenna systems for various applications. He is project coordinator of SILIKA, a European H2020 Innovative Training Network project to develop mm-wave base-station concepts for 5G wireless systems. Moreover, he leads the Ultra-High-Data-Rate program within TU/e's Center for Wireless Technology.
Academic background
Ulf Johannsen received his Dipl.-Ing. degree in Communications Engineering from Hamburg University of Technology (TUHH, Germany) in 2009. In 2013, he obtained his PhD in Electrical Engineering from Eindhoven University of Technology (TU/e, the Netherlands). He then started as Senior Systems Engineer at ATLAS ELEKTRONIK GmbH (Bremen, Germany), where he worked as system designer and engineering manager on autonomous underwater vehicle (AUV) systems with sonar payloads. In 2016, he was appointed Assistant Professor with the Electromagnetics group at the TU/e department of Electrical Engineering. Ulf Johannsen is chair person of the IEEE Benelux joint AP/MTT chapter and a member of VDE.
