Abstract: Base station antennas include an externally accessible active antenna module releasably coupled to a recessed segment that is over a chamber in the base station antenna and that is longitudinally and laterally extending along and across a rear of a base station antenna housing. The base station antenna housing has a passive antenna assembly that cooperates with the active antenna module.

Abstract: A phase shifter assembly, suitable for a base station antenna, includes a main printed circuit board with opposing first and second primary sides. The main printed circuit board has a plurality of radio frequency (RF) transmission paths on the first primary side and a plurality of RF transmission paths on the second primary side. The phase shifter assembly also includes a first wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the first primary side of the main printed circuit board; and a second wiper arm rotatably coupled to the main printed circuit board and electrically coupled to the plurality of transmission paths on the second primary side of the main printed circuit board. Rearwardly extending phase shifter assemblies that are oriented perpendicular to a plane defined by a reflector within a base station antenna are also provided.

Abstract: The present disclosure relates to a switchable transmission mechanism for a base station antenna. The switchable transmission mechanism includes a plurality of axially drivable members, each of which is mounted on a corresponding one of a plurality of transmission rods arranged in parallel and is configured to be connected with a corresponding one of a plurality of phase shifters in the base station antenna; a transmission unit including a first gear assembly and a second gear assembly transmissibly connected to the first gear assembly, where the second gear assembly is engageable with or dis-engageable from any one of the transmission rods via a rod adapter that is movable between an engaged position and a disengaged position along an axial direction; and a switch unit configured to move the second gear assembly along a lateral direction perpendicular to the axial direction when the second gear assembly is disengaged from the transmission rod, so that the switchable transmission mechanism can selectively drive any one of the transmission rods.
