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: An apparatus includes a housing comprising a first ground plane surface and a second ground plane surface and a wiper-type phase shifter within the housing that is electrically coupled to a first plurality of conductive lines and a second plurality of conductive lines, the wiper-type phase shifter, the first plurality of conductive lines, and the second plurality of conductive lines being separated from the first ground plane surface and the second ground plane surface by a dielectric material.

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: A tilt indicator constructed from a flexible material allows the tilt indicator to bend without breaking when subjected to bending loads. The tilt indicator may take the form of an elongated rod with indicia imprinted thereon. The indicia may be indicative of the degree of tilt of an antenna to which the tilt indicator is attached.
