Student will get strong knowledge about theory of electromagnetic field radiation and basic principles of antenna design.

Methods of analysis are demonstrated on various types of antennas and their arrays.

Seminars are both theoretical (analytical and numerical calculation using MATLAB and EM simulators CST) and practical (measurement of antenna parameters).


Good knowledge of electromagnetic field theory (electrodynamics), vector analysis and calculus.

Max. two leaves, in case of measurement seminars student has to perform measurement with other group.

Worked reports on antenna measurements are required.
