Prerequisites
General Prerequisites
1. Basic circuit theory
2. Basic analog electronics
3. Electromagnetic field theory
4. Electromagnetic wave propagation
Learning Outcomes
1. Thorough understanding of the transmission line concept, as opposed to common lumped circuits.
2. Ability to analyze simple and complex transmission line circuits by writing down equations and appropriate computer programs (e.g. Matlab).
3. Understanding and applying RF circuit design principles, including matching circuits, with the use of Smith Chart.
4. Understanding of guiding wave principles and physics in metallic and dielectric waveguides.
5. Designing and printing RF circuits (in a special laboratory session), based on planar transmission lines (microstrips, coplanar waveguides etc).
6. Understanding basic principles of electromagnetic radiation and the the concept of the dipole.
General Competences
- Apply knowledge in practice
- Retrieve, analyse and synthesise data and information, with the use of necessary technologies
- Work autonomously
- Work in teams
- Be critical and self-critical
- Advance free, creative and causative thinking
