Course detail

Design of Antennas and Radio Links

FEKT-FYOeAcad. year: 2015/2016

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.

Learning outcomes of the course unit

The graduate is able to:
- 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);
- explain a principle of the operation and describe basic steps of a design procedure of linearly and circularly polarized microstrip patch antennas;
- explain a principle of the operation and describe basic steps of a design procedure of horn, reflector, and slot antennas;
- explain basic principles of antenna bandwidth increasing;
- explain principles of antennas with an extremely wide band of operation;
- explain basic principles of antenna modeling;
- specify, for a desired frequency band, a dominant mechanism of propagation, appropriate types of antennas, and typical services of operation;
- describe principles of radio wave propagation close to the Earth’s surface;
- describe basic steps of a radio link design;
- describe computation of electric field intensity in a real terrain;
- describe exploitation of propagation curves for the determination of electric field intensity;
- explain principles of wave propagation and modeling in the area of mobile communication, and explain deterministic, empirical and semi-empirical propagation model;
- describe a principle of an empirical model creation;
- describe influence of atmosphere on radio links;
- explain „digital microwave link“, specify its pros and cons, explain quality criterions and basic steps of digital microwave link design.

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 (Maxwell’s equations, elementary radiation sources, propagation of plane and spherical wave, propagation of a wave along transmission line).
