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 dipole antenna includes a planar reflector and a radiating element. The radiating element includes first and second pairs of dipoles on a surface of the planar reflector. The first and second pairs of dipoles respectively include arm segments arranged around a central region in a box dipole arrangement. The arm segments may be printed circuit board portions having respective metal segments and respective inductor-capacitor circuits thereon. The inductor-capacitor circuits define a filter aligned to a frequency range higher than an operating frequency range of the first and second pairs of dipoles.

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: Antennas include first and second radiating elements that are configured to operate in respective operating frequency bands. The first radiating element includes a first dipole arm that has a first conductive path and a second conductive path that is positioned behind the first conductive path. The first conductive path includes a plurality of first segments and the second conductive path includes a plurality of second segments, where a subset of the first segments overlap respective ones of second segments to form a plurality of pairs of overlapping first and second segments. At least some of the pairs of overlapping segments are configured so that the instantaneous direction of a first current formed on the first segment in response to RF radiation emitted by the second radiating element will be substantially opposite the instantaneous direction of a second current formed on the second segment in response to the RF radiation.

Abstract: A base station antenna includes a column of radiating elements comprising first and second sets of radiating elements, each radiating element being configured to operate in a first frequency band that has first and second sub-bands. The second set of radiating elements is located above and/or below the first set of radiating elements. The antenna further includes a feeding assembly that is configured to feed first RF signals that are in the first sub-band and second RF signals that are in the second sub-band to the column of radiating elements, where the feeding assembly is configured to partially attenuate sub-components of the second RF signals that are fed to the second set of radiating elements more than sub-components of the first RF signals that are fed to the second set of radiating elements.
