ELEC5101: Antennas and Propagation
The basics of antenna radiation are introduced with emphasis on the important performance characteristics of the radiation field pattern (in 3 dimensions) and feed impedance. The omnidirectional and Hertzian dipole antennas (both hypothetical in practise but robust theoretically) provide the starting point to analyse real antenna operation. Mutual coupling between close antennas and important 'ground' imaging effects lead to the design of antenna arrays to increase gain and directivity. Aperture antennas and frequency broadbanding techniques are introduced. Ionospheric propagation is discussed and also the the reception efficiency of receiving antennas which allows consideration of a Transmitter - Receiver 'Link budget'. The important 'Pocklington' equation for a wire dipole is developed from Maxwell's equations and leads to the numerical analysis of wire antennas using 'Moment' methods. Real world applications are emphasised throughout and are reinforced by the hands on laboratory program which includes design projects.

At the completion of this unit, you should be able to:
- LO1. analyse and design solutions for antennas operating up to and including the microwave frequency level, by drawing on concepts and principles of antenna theory and practice
- LO2. demonstrate an understanding of antenna theory and practise
- LO3. demonstrate an understanding of antenna performance, as well as signal propagation and the associated link budget to the extent of the material presented
- LO4. demonstrate an understanding of the process of designing a broad variety of antenna systems using principles, concepts and tools taught throughout the course
- LO5. demonstrate an ability to develop the fundamental 'Pocklington Equation' for wire antennas which leads to the powerful computer based 'Moment Method' of analysis
- LO6. write and maintain a laboratory log book to communicate problem-solving activities by using clear and concise language, sketches and diagrams at a technical level fitting for the tasks performed
- LO7. conduct team work by assuming various roles as needed, demonstrating initiative and receptiveness to the viewpoints of others in the group so as to tackle and test design challenges.
