Abstract
An antenna system includes a plurality of cascading power dividers that work in conjunction with a plurality of mechanical phase shifters to vary a beamwidth and/or an azimuth scan angle of a beam that radiates from active columns. Each phase shifter has an independent remotely controlled drive and is directly electrically connected to a respective radiating column. The radiating columns include cross dipole antenna elements.
