Course detail

Design of Antennas and Radio Links

FEKT-LASVAcad. year: 2013/2014

The subject is focused on the explanation of basic principles of the antenna theory and radio wave propagation, and their exploitation for antenna and radio links design. Students will practice their knowledge on the design, manufacturing and measuring of a given antenna, and on the design of selected radio links in a real environment.
