Evaluation of course
ILO of the course:
Students should, at the end of the course, be able to:
1. Explain the operation of a given antenna based on its geometry; and describe its
expected performance in terms of radiation pattern, efficiency, bandwidth, and
polarization.
2. Define the required specifications of an antenna for a given application.
3. Judge, by using physical constraints, if an antenna can fulfil some given
specifications.
4. Design an antenna for some given feasible and realistic specifications.
5. Simulate, evaluate the performance and design antennas using commercial
software: CST Microwave Studio or HFSS.
6. Measure the performance of an antenna by using standard microwave equipment.
The equipment includes vector network analysers, a spectrum analyser, a near-field
scanner, a signal generator and an anechoic chamber.
7. To find, understand and use relevant technical literature to solve antenna problems.
