Educational goal:

Getting to know the characteristics and engineering concepts of microwave passive components and subsystems. Students will acquire fundamental knowledge in the field of of modeling, simulation and design of modern microwave passive circuits. Training students for computer design of microwave circuits using specialized software packages for 2D and 2.5D circuits (Microwave Office) and 3D circuits (CST, COMSOL, HFSS).

Educational outcome:

Fundamental theoretical and practical engineering knowledge about of computer design of the modern passive components and circuits used at frequencies above 1 GHz. Understanding the basic concepts and steps in the design of microwave resonators, filters, antennas, power dividers, couplers, and attenuators. Students will be trained for design of microwave circuits by using modern CAD software packages through the following phases: creating model, performing numerical simulations, creating a layout, verification of laboratory prototype by measurement.
