The Microwave Engineering Laboratory (www.mel.diei.unipg.it) of the Dept. of Electronic and Information Engineering of the University of Perugia, headed by Professor Roberto Sorrentino, has been involved since more than 20 years in the development of numerical methods and CAD techniques for the analysis and design of microwave and millimetre-wave circuits both in conventional (waveguide) and integrated technologies (hybrid and monolithic) including antennas and antenna arrays. Various numerical techniques have been developed both in time and frequency domains, such as modal techniques, transverse resonance analysis, Finite Difference Time Domain method, integral equation method, hybrid methods, etc. Electromagnetic simulators, based on the Finite Difference Time Domain (FDTD) method, Mode matching technique and MoM, have been developed over the years for the analysis of EM structures both in time and frequency domains, for both linear and nonlinear circuits. Design tools for the analysis and design of scanning active antenna arrays have been developed. Specific algorithms have also been developed for real time beam shaping and adaptive nulling, suited for reconfigurable and smart antenna systems.

Since 2000 the Perugia research group has been strongly involved in the modelling, simulation and design of RF MEMS circuits and components. Specifically for RF MEMS, Perugia has been working on the development of rigorous electromagnetic models for the accurate characterisation of RF MEMS structures taking into account large scale integration elements (vias, impedance and geometry transitions, interconnects), 3-D proximity effects and packaging effects. Other topics under development are the analysis of the influence of package materials and fabrication techniques on RF performance and the study the influence of bond wires, epoxy and solder joints.

Perugia has been involved in several international projects on RF-MEMS. Here we mention the most recent ones:
