EM Waves and Lines
FEKT-HEVAAcad. year: 2018/2019
Mobile communication systems are based on the propagation of electromagnetic waves in the environment. Waves are transmitted and received by proper antennas. Antennas have to be completed by a suitable transmission line with high-frequency transmit circuitry and receive one. Wave propagation, antennas and transmission lines can be numerically modeled in computer programs. Lectures are aimed to present the described topics to the beginners in the field.
Learning outcomes of the course unit
The graduate is able (1) understand fundamental properties of electromagnetic field, (2) evaluate propagation of waves in free space and on transmission lines, (3) exploit basic methods for the analysis of antennas and transmission lines, (4) provide overview of properties of various types of transmission lines, (5) technically apply antennas and transmission lines.
Knowledge of bachelor mathematics (fundamentals of the differential calculus and integral calculus) and physics (fundamentals of electrostatics, stationary magnetic fields and dynamic electromagnetic fields) and lower intermediate English are required.
