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: Base station antennas include a reflector, a first array of cross-polarized radiating elements that are mounted to extend forwardly from the reflector, and a parasitic assembly. The parasitic assembly includes a base that is mounted on the reflector, a horizontal component shaping element, and a forwardly projecting member that projects forwardly from the base that is coupled between the base and the horizontal component shaping element, The horizontal component shaping element may extend substantially parallel to a plane defined by the reflector and may include a proximate side that is directly connected to the forwardly projecting member and a distal side that is opposite the proximate side. The distal side of is only electrically connected to the reflector through the proximate side.

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.
