Abstract :
This paper describes an experimental UHF antenna employing a 4- element circular array to provide omnidirectional coverage, plus the facility to incorporate automatic null steering against a strong interfering signal. The control is exercised by a microcomputer on line and the concept can offer simultaneous operation for multiple narrowband users with standard receivers.
