Employment Enquiries




Dr. Matthias John is a Senior Researcher at the Antenna & High Frequency Research Centre. His research is funded by [external]CONNECT - Centre for Future Networks. He joined the group in 2004, having received the Dipl.-Inf. (FH) degree in Telecommunications and Computer Science from the [external]Deutsche Telekom University of Applied Science Leipzig, Germany. He completed his PhD in November 2008.
He has worked on on subjects including Ultra Wideband Antennas, Evolutionary Optimization Techniques and Antenna Miniaturization. The optimisation techniques he developed are employed in the AHFR centre to optimise antennas for applications in most research areas.

Matthias has implemented genetic algorithms and other advanced evolutionary optimisation algorithms for various computing architectures in Matlab and Perl programming languages. He has also helped to develop and setup the AHFR Laboratory’s manufacturing and measurement systems, IT infrastructure and this website.

He is currently working on small, reconfigurable antennas for IoT and M2M embedded devices. Focusing on installed performance and efficiency. He is also working on RFID antennas for ticketing/access systems and contactless payment cards and readers.
