Overview

This course is designed to provide an overview of the fundamental principles associated with microwave and RF antennas and propagation. It 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.

This course is usually very popular so early booking is advised.

"Lab demonstrations add value to previous lectures and prompted a good discussion. Liked Tim’s flexibility in approach when dealing with different experience levels… Wanted to keep his first antenna!"
