Vita

Tobias Chaloun  received the Dipl.-Ing. degree and the Dr.-Ing. degree (with honors) in electrical engineering both from the University of Ulm, Ulm, Germany, in 2010 and 2016, respectively.

From 2010 to 2016, he was a Research Assistant at the Institute of Microwave Engineering (MWT), Ulm University, Germany where he conducted his doctoral studies in the field of highly-integrated antenna systems for communication applications at millimeter wave frequencies.

Since January 2017, he is a Senior Researcher and Lecturer at the Institute of Microwave Engineering. His main research interest concerns multilayer antennas and circuits, millimeter-wave packaging and interconnects, phased array antenna systems and millimeter-wave radar sensors.

Dr. Chaloun is member of the European Microwave Association and the Institute of Electrical and Electronics Engineers. Currently, he serves as a reviewer for the IEEE TRANSACTIONS ON A NTENNAS AND PROPAGATION and IEEE TRANSACTIONS ON MICROWAVE THEORY AND TECHNIQUES.

Dr. Chaloun was the recipient of the Best Paper Award at the German Microwave Conference in 2015. In 2016, he has been awarded for the Best Paper in the IET Microwaves, Antennas & Propagation.

  • (08/2016) Best Paper in IET Microwaves, Antennas & Propagation

    T. Chaloun, M. Kaynak, W. Menzel, Q. Luo, T. Purtova, S. Gao, V. Ziegler, H. Schumacher, F. Tabarani, and R. Starec, “Wide-angle scanning active transmit/receive reflectarray,” IET Microwaves, Antennas & Propagation, Vol. 8, No. 11, P. 811–818, August 2014.

    Abstract:

    A highly integrated phased array transmit/receive architecture is presented. Multilayer microstrip antennas with a scanning potential up to 60° are combined, on a common manifold, with SiGe MMICs including four RF channels each, together with the necessary digital control circuits. Power distribution and combining are realised by the concept of a folded planar reflectarray. This study also includes the necessary solutions for multilayer interconnects and efficient heat removal from the active circuits. To prove the concept, passive arrays with different fixed beam positions have been tested successfully; followed by a first active array demonstrating excellent scanning performance up to 60° both in E- and H-plane.

  • (03/2015) Best Paper Award at the German Microwave Conference

    T. Chaloun, C. Hillebrand, C. Waldschmidt, and W. Menzel, “Active Transmitarray Submodule for K/Ka Band Satcom Applications,” in 9th German Microwave Conference, March 2015, P. 198–201.

    Abstract:

    A novel concept for an active transmitarray architecture for K/Ka Band Satcom applications is presented. The highly-integrated antenna system is based on planar multilayer arrangement covering both Satcom frequency bands for uplink at 30 GHz and downlink at 20 GHz. To verify the proposed manifold approach, the individual components and a first active dual-band transmitarray submodule enhanced by a multi-functional SiGe BiCMOS MMIC have been realized and measured successfully.
