Subject fundamentals
The course is taught in English.

All wireless systems are based on the radiation and/or reception of electromagnetic waves. The success of wireless connections (cellular networks, WLAN, Bluetooth, etc.) relies on the fact that electromagnetic fields are pervasive; in turn, this also poses a threat to proper operation of all electronic systems, and motivates the need to understand, control and/or mitigate electromagnetic interference ' which is a key topic of the electromagnetic compatibility (EMC).
This course addresses engineering of electromagnetic field radiation in relevant applications in electronics and communications. This includes intentional radiation and reception of waves, as in antenna theory and design, as well as unwanted radiation and reception of fields (i.e., interference), that is, EMC.
Knowledge of antennas is a key competence in communication system design; understanding the limitations imposed by electromagnetic interference is a necessary competence not only in communication systems, but also for any electronic hardware, all the way down to modern integrated circuits design.
Expected learning outcomes
Knowledge of methods to assess wanted and unwanted radiation of electromagnetic fields.
Knowledge of the main classes of antennas currently in use in relevant wireless systems.
Knowledge of basics of radiated susceptibility (EMC).
Knowledge and ability to understand regulations and recommendations for exposure to (non-ionizing) electromagnetic radiation.
Ability to understand the requirements of antennas in relevant wireless systems.
Ability to carry out basic design of some relevant antenna types.
Ability to assess EMC issues for some relevant classes of configurations.
Prerequisites / Assumed knowledge
Basics of Radiation of EM fields;
Basics of Antennas (definition of fundamental parameters);
Basics of Link budget;
Contents
Review of radiation of electromagnetic fields (intentional and non-intentional sources); reciprocity and reception/interference 10 h
Review of antenna fundamentals, antenna and/or sensors requirements in relevant systems and EMC tests 8 h
Wire and broadband antennas: biconical antenna, dipoles, Yagi-Uda, loop, log-periodic 10 h
Symmetry and balancing; common/differential mode radiation and susceptibility 8 h
Aperture-type antennas: Horns, Slots, Printed antennas (microstrip), Reflectors 18 h
Arrays, beam-forming and signal-combining/splitting networks 16 h
Overview of regulations for EMC, and regulations and recommendation for exposure to electromagnetic fields 6 h
Measurements for Antennas and EMC 4 h
Delivery modes
A key component of the learning activity are problem-solving classes and home assignments. Measurement laboratory sessions are planned for about 4h. Optional lab on special projects.
Texts, readings, handouts and other learning resources
The learning will be supported by handouts made available by the instructor. A bibliography of useful reference textbooks (not necessary for course activity, only to probe further) will be also made available on the web portal.
Assessment and grading criteria
Standard final exam has a written problem-solving test; optional written or oral test on theory. Submission of completed assignments will grant an additive bonus. Special projects may substitute for the theory test in some cases, as published on the course page of the web portal.
