NARROW BEAM ANTENNA SYSTEMS WITH ANGULAR DIVERSITY

摘要

A receiving system (100) is disclosed which includes at least one antenna (101) providing a plurality of antenna beams. A first processing branch (103) is included for processing a first plurality of signals appearing within a first plurality of antenna beams. The first processing branch (103) includes a plurality of delay paths (105) each receiving a one of the first plurality of signals from a corresponding one of the first plurality of antenna beams and applying a predetermined amount of delay thereto, the preselected amount of delay proportionate to the corresponding one of the beams. First processing branch (103) further includes a combiner (106) for combining the first plurality of signals after output from the plurality of delay paths (105). A second processing branch (104) is provided for processing a second plurality of signals appearing within a second plurality of the antenna beams.
