Abstract: RET assemblies suitable for base station antennas are provided that include a gear plate with a plurality of arms that extend in a longitudinally upward direction and a plurality of arms that extend in a longitudinally downward direction. The gear plate is coupled to a motor and lead screw that drive the gear plate, which in turn, rotates gears coupled to the gear plate. The gears rotate wipers of phase shifters in synchronization.

Abstract: Reflector assemblies suitable for active antenna units and/or base station antennas are provided that include a reflector body and a lip extending about a perimeter of the reflector body. The reflector body can optionally include a plurality of fin structures extending about a least part of a perimeter of the reflector body. The fin structures and/or side walls of the reflector body can be directly exposed to environmental conditions during use. The fin structures, where used, can be shaped channel members that can be formed of sheet metal or provided as separate extruded or die cast members that can be coupled to the reflector body.

Abstract: A multi-mode antenna includes a feed network including a cascaded arrangement of a first phase shifter and hybrid coupler pair, which is responsive to a radio frequency (RF) input feed signal, and a second phase shifter and hybrid coupler pair, which is responsive to an RF feed signal generated at a second output port of the first phase shifter and hybrid coupler pair. First, second and third arrays of radiating elements are provided. The first array is responsive to a RF feed signal derived from a first output port of the first phase shifter and hybrid coupler pair; the second array is responsive to an RF feed signal derived from a first output port of the second phase shifter and hybrid coupler pair; and the third array is responsive to an RF feed signal derived from a second output port of the second phase shifter and hybrid coupler pair.
