Description including Unit Aims

Antennas: The antenna is an integral part of any wireless communications system. The module outlines basic principles and analysis of antennas.

The first part of this module concentrates on defining and practical measurement of antenna characteristics. Array theory is then developed using isotropic sources, and this includes both analysis of linear and planar arrays as well as pattern synthesis. Examples of practical antennas are considered, concentrating on dipoles and patch antennas. The latter is used for practical laboratory work in this unit.

Electromagnetic Compatibility: This course is designed to give an appreciation of the range of issues involved in the design and testing of equipment in such a way as will comply with EMC standards and operate successfully when used in systems. The approach is deliberately chosen to be broad rather than deep so that the students will obtain the necessary background in order for them to be able to investigate specific problems which they may encounter in the future.

  • EMI measurements and instrumentation;
  • EMI modelling and prediction.

Intended Learning Outcomes

Antennas

By the end of the unit, students should be aware of the mechanisms that give rise to electromagnetic radiation. They should be aware of a variety of antenna geometries and their RF characteristics. This will allow students to be able to identify suitable antennas for particular applications, given system specifications.

Electromagnetic Compatibility

At the end of this unit, students will be aware of the pitfalls which exist in designing for EMC. Specifically they will be aware of circuits and structures which are likely to give rise to interference such as loops and long wires. They will be able to calculate crosstalk levels on wires and printed circuit tracks, given their distributed parameters. They will be aware of the properties of "real" components such as capacitors, inductors and filters, their behaviour at high frequencies and the most effective ways to use them to improve EMC performance. They will be aware of the properties of different screening materials and their effect on different types of interference source. They will be aware of different grounding schemes which are possible and their advantages and disadvantages at different frequencies. They will see how an EMC test is carried out and gain an appreciation of the interference signal levels which can be expected from certain types of equipment and wiring. They will be aware of the EMC modelling tools which are available, their uses and limitations.
