Abstract
Considerable development has taken place in the fields of information technology, data processing and communication systems which has resulted in a number of prototype automatic data- communication system being developed using infra- red beam, satellite, radio and inductive- loop technologies. A low energy microwave system currently under development on a serc- financed project at Newcastle offers, improved performance over the above systems due to the small size, low cost and high data- transfer rates achieved. Following a brief review of the background and applications of the system, the paper discusses the design and development of a low profile microwave receiver.
