The new 5G wireless communication paradigm requires high-performance antenna systems that are unobtrusively and invisibly integrated and that provide stable radiation characteristics in a wide range of adverse conditions. In addition, such antenna topologies must be low-cost and low-profile and conform to the surface on which they are deployed, or they should be flexible.

Since more than a decade, we have been developed dedicated design frameworks for such antenna systems in the context of body-centric communication, the Internet-of-Things and the 5G system. By applying advanced full-wave-circuit co-optimization, an optimal interconnection between the antenna module and the active transceiver and power management electronics is implemented.

The group is also very active in the field of Electromagnetic Compatibility and Signal/Power Integrity, mainly in the context of electromagnetic immunity and emission models for integrated circuits (ICs). For example, we model electrically large test benches which are used in the EMC automotive industry, we model both narrow band EMC tests and broadband EMC tests.

Examples of this are: capacitive coupled test, inductive coupled test, ESD test, bulk current injection test, direct power injection test,… We also investigate power integrity and signal integrity such as serpentine delay lines, bend discontinuity, power-ground buses, non-uniform multi-conductor transmission lines,… at which we also study the functionality under hazard condition such as radiation immunity.
