Description

The antenna is an integral part of any wireless communications system. This unit predominantly considers intentional radiators (i.e. antennas), though also provides a basis for analysis of unintentional electromagnetic radiation (i.e. potential sources of interference). The first part of the unit concentrates on defining, and practical measurement of, antenna characteristics. Antenna array theory is then developed to show how the antennas radiation pattern can be shaped and steered. The application and design of some of the wide variety of antenna configurations is considered, with examples given of practical antennas (dipoles, slots, arrays, reflectors). It is also important to show how the antenna is integrated with feed-lines and RF circuitry. This area is covered in lectures and reinforced through a design exercise where students have to specify antenna and RF component requirements for a satellite communications system downlink.

Intended learning outcomes

By the end of the unit, students will be able to:

  1. outline what is meant by electromagnetic radiation;
  2. explain basic antenna characteristics (matching, transmission and polarisation);
  3. analyse RF characteristics of some antenna element geometries;
  4. analyse linear and planar antenna arrays;
  5. formulate antenna weighs to shape and steer antenna array radiation patterns;
  6. produce outline antenna designs (gain requirement) for particular applications given system specifications;

Teaching details

Teaching will be delivered through a combination of synchronous and asynchronous sessions, including lectures, practical activities supported by drop-in sessions, problem sheets and self-directed exercises.
