Antennas and Propagation
18-22 November 2013
The short course course is designed to provide an overview of the fundamental principles associated with microwave and RF antennas and propagation. The course will present the underlying theory in an accessible manner, together with techniques for application of the theory to satellite and mobile communications scenarios as well as broadcasting and indoor wireless applications. The course is partly based on a MSc modules taught at Surrey University. Topics include antenna principles and calculations from electromagnetic theory; radio propagation modelling, overcoming channel impairments, antenna design with the inclusion of laboratory demonstrations.
The course is usually very popular so early booking is advised.
Professor Simon Saunders's book on "Antennas and Propagation for Wireless Communications Systems" is included in this course.
Please note that this syllabus can be changed at the University of Surrey's discretion.
1. Introduction and Antenna Fundamentals I and II – Dr Tim Brown
An introduction to the whole course and its structure. What is an antenna? Why does antenna design and propagation modelling matter? Examples of applications in this regard. Overview of relevant textbooks in the field.

Following the introduction to antennas, this session will cover a brief introduction to the different types of antennas such as a Yagi-Uda antenna, Horn Antenna, helical antennas, microstrip antenna, slot antenna, Reflector Antennas and others. It will also introduce the concept of array antennas where multiple antenna elements can be combined. This will include 1-D and 2-D array antennas.
