METHOD AND APPARATUS FOR BEAM-STEERABLE ANTENNA WITH SINGLE-DRIVE MECHANISM

摘要

In one embodiment, an antenna assembly is described. The antenna assembly includes and antenna and an antenna positioner coupled to the antenna. The antenna positioner includes a single drive interface and a plurality of gears. The plurality of rotate in a first manner in response to a first drive direction applied through the single drive interface, and rotate in a second manner in response to a second drive applied through the single drive interface. The antenna positioner also includes a threaded rod that moves in a first rod direction and a second rod direction in response to rotation of the plurality of gears in the first manner and the second manner respectively. The antenna positioner also includes a tilt plate contacting the threaded rod. The tilt plate tilts about a pivot line in response to movement of the threaded rod to move a beam of the antenna in a spiral pattern.
