Abstract
A dynamically variable beamwidth and/or variable azimuth scanning antenna includes a plurality of active radiating columns and a plurality of continuously adjustable mechanical phase shifters. The columns define a beam having a beamwidth and an azimuth scan angle. Each phase shifter has an independent remotely controlled drive and is directly electrically connected to a respective radiating column. The phase shifters are independently operated to vary the beamwidth and/or azimuth scan angle of the beam defined by the plurality of active radiating columns.
