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 at the first primary side and a plurality of RF transmission paths a t 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 at 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 at 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. 适用于基站天线的移相器组件包括具有相对的第一主侧和第二主侧的主印刷电路板。所述主印刷电路板具有所述第一主侧上的多个射频(RF)传输路径和所述第二主侧上的多个RF传输路径。所述移相器组件还
