Abstract:
The Electromagnetic Waves Propagation and Antennas course aims to acquaint the students from the degree
course in Electronics with the peculiarities of the electromagnetic waves propagation in different media and with
the parameters of some types of antennae, antenna grades and transmitter lines. The subject requires knowledge
of Physics and Theory of electrical engineering.
Course content:
Main notions and equations of the electromagnetic field. Flat electromagnetic wave in unlimited medium.
Polarization of electromagnetic waves. Reflection and penetration of an electromagnetic wave into the border
between two media. Influence of the earth surface over the propagation of the electromagnetic waves. The
ionosphere and its influence over the propagation of the electromagnetic waves. Peculiarities of the propagation of
the electromagnetic waves with frequencies under 30MHz. Peculiarities of the propagation of the electromagnetic
waves with frequencies over 30MHz. Transmitter lines: waveguides, lines with surface waves. Compatibility and
symmetry of the lines with the load. Emission from linear conductor. Symmetrical vibrator. Vibrator system –
reflectors and directors.
Teaching and assessment:
Lectures last 2 hours each (1x2 hours). The exercises last 4 hours and are held every other week. The mark is
formed as a total mark on the basis of two written tests, the first one is done during the 7 th week of the semester,
and the second test is done during the 15 th week of the semester. Each test has a duration of 2 hours.
