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.

Abstract: A radiator assembly for a base station antenna includes two dipoles arranged in a cross-over manner, each dipole including two dipole arms, and two feeding lines, each feeding line being associated with a respective one of the dipoles. Each dipole arm is integrally formed of sheet metal, and includes a radiating surface and a leg projecting from the radiating surface at an angle with the radiating surface, where the leg is electrically grounded.
