Module aims
Subject content aims:
-
To introduce students to the properties of antennas that describe their use in radio communications systems
-
To introduce students to the basic physics of the operation of antennas
-
To introduce the most commonly used modes of radio propagation in the Earth's atmosphere
-
To provide an insight into the physics of these modes
-
To illustrate common uses of these modes, and to enable students to estimate the channel losses in each case
-
To understand the physical and mathematical basis of distributed-circuit techniques in RF and microwave engineering, and their practical application in RF and microwave design
-
To introduce students to the concept of noise and interference in electronic systems and to describe the sources, effects and control of noise and interference
-
To introduce students to the design of waveguides for the most important technical application, including optical fibre links.
Graduate skills aims:

Additional assessment information
The laboratory assessments are intended to test your understanding of the experiments carried out and provide some feedback on reporting. The closed book exam tests your ability to analyse problems and explain concepts covered in the module.
Laboratory assessments will be a mix of formative and summative and will run through the semester.

Module feedback
'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments. A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback.
The School of PET aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. The School will endeavour to return all exam feedback within the timescale set out in the University's Policy on Assessment Feedback Turnaround Time. The School would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The School will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
Formative Feedback
-
Questions can be asked at any time, and will be answered as soon as possible.
-
Practicals and workshops will provide an opportunity for discussion and formative feedback
Summative Feedback
-
General feedback will be published.
-
Lab assessments are annotated with some feedback
