Abstract :
One of the most useful applications of antenna arrays is interference rejection. This paper describes an antenna array that was designed for the sole purpose of rejecting interference of a satellite receiver from a close-proximity jamming source. Since this jammer can move relative the satellite antenna, the antenna array must adaptively adjust its null direction accordingly. The system consists of a six-element array of circular fractal patch antennas in conjunction with a receiver channel that is dedicated to interference detection and tracking.
