Learning outcomes
|
The first part of the course is focused on the theory of electromagnetic wave propagation in the open environment, in buildings and in specific environments such as the ionosphere and others. The next part of the course is focused on the definition of basic parameters of antennas and their measurement in free space and in the anechoic chamber. The main part of the course is devoted to a theoretical description of important types of antennas, their design and calculations of parameters of these antennas. The conclusion of the course is devoted to methods of synthesis of linear antenna arrays and planar antenna arrays and their realizations.
The student will gain knowledge in the field of electromagnetic waves in free space and in trannsmision liness. He will also be acquainted with the basic types of antenna elements and the measurement of their parameters. They will also get acquainted in detail with the methods of synthesis of linear antenna arrays.
