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 application. It is intended to run the course face to face.
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!Comment from previous student
On successful completion of this course, you will be able to:
- Explain the fundamental parameters of antennas, such as: gain, impedance, and efficiency. Explain the basic principles of operation of a type of antenna
- Have practical experience in designing and testing antennas
- Explain propagation behaviour in practical scenarios and how to apply propagation models to advanced representative problems.
Content includes the following:
- Antenna principles and calculations from electromagnetic theory
- Radio propagation modelling
- Overcoming channel impairments
- Antenna design with the inclusion of laboratory demonstrations.
Please note that we reserve the right to alter the syllabus. Any major changes will be notified to delegates before the course starts.
