General description

Since 2009 the Institute for Communications Engineering and RF-Systems (NTHFS) at the Johannes Kepler University (JKU) is located in the Mechatronics building in the Science Park.
With a staff of more than 20 researchers and 2 professors (Prof. Springer – Communications Engineering Department, Prof. Stelzer – RF Systems Department) JKU/NTHFS is working on concepts and circuit design of microwave sensors in various frequency ranges up to 170 GHz, architectural concepts for multi-band/multi-mode capable transceivers for cellular communication systems, signal processing for radar sensing and wireless communications, and wireless sensor networks for industrial applications. JKU/NTHFS is involved in the COMET K2 Center “Austrian Center of Competence in Mechatronics (ACCM)”, funded by the Austrian Federal government, where it is responsible for the area “Wireless Technology”. Since 2007 NTHFS hosts the Christian Doppler Research Laboratory (CD-Lab) for Integrated Radar Sensor, which is headed by Prof. Stelzer. The research topics cover concept engineering and circuit design as well as signal evaluation for highly integrated radar sensors based on SiGe technology for automotive and industrial applications. The team involved in the DOTFIVE project belongs to the RF-Systems department of NTHFS.

Role/activity in the project


The circuit design team of the RF-Systems department is involved in WP5 to design both single core components as e.g. VCO, divider, amplifier as well as complete radar transceivers at 94 GHz, 122 GHz and 140 GHz consisting of numerous RF components. Furthermore demonstrators including baseband electronics and evalution algorithms are project goals.


People involved in the project

Andreas Stelzer

Andreas Stelzer received the Diploma Engineer degree in electrical engineering from the Technical University of Vienna, Vienna, Austria, in 1994, and the Dr. techn. degree (Ph.D.) in mechatronics from the Johannes Kepler University, Linz, Austria, in 2000.
Since 2007, he has been Head of the Christian Doppler Laboratory for Integrated Radar Sensors, and since 2011 he is full Professor at Johannes Kepler University, heading the department for RF-Systems. He has authored or coauthored over 245 journal and conference papers. His research is focused on microwave sensor systems for industrial and automotive applications, RF and microwave subsystems, surface acoustic wave (SAW) sensor systems and applications, as well as digital signal processing for sensor signal evaluation.
Dr. Stelzer was the recipient of several awards including the EEEfCOM Innovation Award and the European Microwave Association (EuMA) Radar Prize of the European Radar Conference. He was also the recipient of the 2011 German Microwave Conference (GeMiC) Best Paper Award as well as of the 2008 IEEE Microwave Theory and Techniques Society (IEEE MTT-S) Outstanding Young Engineer Award and the 2011 IEEE Microwave Prize.

Martin Jahn

Martin Jahn received the Dipl.-Ing. degree in mechatronics from the  Johannes Kepler University, Linz, Austria in 2007. Since 2007 he is with  the Institute for Communications Engineering and RF-Systems at the  University of Linz, Austria and since 2008 he is working towards the Ph.D.  degree as a Research Assistant. His research interests include RF and  millimeter-wave integrated circuits with emphasis on system design for  millimeter-wave radar sensors operating above 100 GHz.

Andreas Springer is a full professor at JKU/ICIE. He has been engaged in research work on GaAs integrated millimetre-wave TED's, MMIC's, millimeter-wave sensor systems, and UWB. His current research interests are focused on wireless communication systems, single- and multi-carrier communications, architectures and algorithms for multi-band/multi-mode transceivers, UMTS/HSDPA/LTE, and recently wireless sensor networks. In these fields, he has published more than 150 papers in journals and at international conferences.
