Course detail

Antennas and Propagation

FEKT-MPA-ANPAcad. year: 2022/2023

The subject is focused on the explanation of basic principles of the antenna theory and radio wave propagation with particular attention mainly on space applications. Students will practice their knowledge on the design, manufacturing and measuring of a given antenna.

Learning outcomes of the course unit

The graduate is able to:
(a) explain a principle of the operation and describe basic steps of a design procedure of selected types of linear antennas (dipole, monopole, folded dipole, log-periodic antenna, Yagi antenna, helix antenna);
(b) explain a principle of the operation and describe basic steps of a design procedure of linearly and circularly polarized microstrip patch antennas;
(c) explain a principle of the operation and describe basic steps of a design procedure of horn, reflector, and slot antennas;
(d) explain basic principles of antenna bandwidth increasing;
(e) explain a term "electrically small anntena";
(f) explain basic principles of antenna modeling;
(g) explain basic requirments on antennas for satellites;
(h) specify basic antenna types for satellites;
(i) explain basic requirments on antennas for Earth station;
(j) specify basic antenna types for Earth station;
(k) explain basic procedures of antenna testing for space applications;
(l) explain basic principles of radio wave propagation;
(m) specify, for a desired frequency band, a dominant mechanism of propagation, appropriate types of antennas;
(n) describe atmospheric effects (attenuation by atmospheric gases, hydrometeor attenuation, depolarization, radio noise, scintillation) on a satellite link;
(o) calculate satellite link budget.

Prerequisites

Students who enroll the course should be able to:
- compute with complex numbers;
- apply fundamental principles of integral and differential calculus;
- explain fundamental principles of electromagnetic field theory.

The work in the laboratory is conditioned by a valid qualification of a "instructed worker" according to 50/1978 Coll., which students must obtain before the start of classes. Information on this qualification is given in the Dean's Directive Familiarization of students with safety regulations.
