Novel antenna tracking mechanism for land mobile satellite terminals

The current interest in land-mobile satellite terminals, using small tracking antennas, has prompted researchers at the University of Bristol, to investigate the applicability of the electronic beam squint (EBS) tracking technique to this environment. The preliminary findings of this investigation are presented. Two systems, are described, based on the EBS technique, which use both conventional waveguide and phased array technology. Results are presented covering the error detection capabilities of the systems and operational performance of two forms of prototype antenna. The described schemes are intended for use at L-band and Ku-band.<
