    Employment
     
    (February 2009 - present) Full-time research assistant (ger. wiss. Ang.") of Prof. Dr.-Ing. Werner L. Schroeder at RheinMain University of Applied Sciences (Russelsheim, Germany) Industry funded project (OPTION N.V.; Leuven, Belgium): Advanced systematic design of multiport antennas for LTE-enabled USB dongles (ADVANT)
     
    Integration of multiport antennas in a small volume o ered by mobile wireless terminals (User Equipment), e.g. mobile wireless modems, laptops, etc., was the goal of ADVANT project. Achieving simultaneously high total per port eciencies and high isolation between antenna ports while covering multiple frequency bands using electrical switching were the most challenging aspects of the project. New systematic techniques for design of electrically switchable and electrically tunable small 2-port MIMO antennas for USB dongles were developed and thoroughly documented. The project resulted in four patents and number of high-quality publications in various international conferences and journals.
