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: The present disclosure has disclosed an antenna mounting device configured to collectively mount a plurality of base station antennas on a mast of a communication tower. The antenna mounting device is substantially in the shape of a polygon, and the mast is disposed at a center of the polygon. The antenna mounting device comprises: a plurality of brackets, which are elongated and include a head bracket, at least one intermediate bracket and a tail bracket attached sequentially; and a bracket fastening mechanism which is disposed between two adjacent ends of the head bracket and an adjacent intermediate bracket, or disposed between two adjacent ends of the adjacent intermediate brackets, or disposed between two adjacent ends of the tail bracket and the adjacent intermediate bracket, and which is configured to move two adjacent ends of the adjacent brackets from a position away from each other to a position close to each other. The antenna mounting device according to the present invention is capable of mounting a plurality of base station antennas on a mast by surrounding the mast in a compact manner, thereby realizing a small-form factor mounting structure.

Abstract: Base station antennas, and components for base station antennas, such as reflectors, feeder components, frames, and column components. A base station antenna may include a reflector; a first radiator located at the front side of the reflector; mutually parallel first and second ground plates extending backward from the reflector and basically perpendicular to the reflector; and a first conductor strip extending between the first and second ground plates and configured to feed power to the first radiator. The first conductor strip and the first and second ground plates may be configured as a first stripline transmission line. The reflector and the first and second ground plates may be configured as one piece so that the reflector is grounded via the first and second ground plates without soldering.
