Abstract: A dual-polarized radiating element includes a first dipole radiator that has a first dipole arm that generally extends along a first axis and a second dipole arm that generally extends along a second axis that is different from the first axis, and a second dipole radiator that has a third dipole arm that generally extends along the first axis and a fourth dipole arm that generally extends along a third axis that is different from the first axis. At least one of the first through fourth dipole arms may be a cloaked dipole arm that include inductive elements that are configured to suppress currents in a higher frequency band.

Abstract: A twin beam base station antenna includes a first array that has a plurality of columns of first frequency band radiating elements, the first array configured to form a first antenna beam that provides coverage throughout a first sub-sector of a three-sector base station. The radiating elements in a first of the columns in the first array have a first azimuth boresight pointing direction and the radiating elements in a second of the columns in the first array have a second azimuth boresight pointing direction that is offset from the first azimuth boresight pointing direction by at least 10°. The radiating elements in the second of the columns in the first array are electrically steered.

Abstract: A sector-splitting base station antenna includes a plurality of RF ports, a plurality of columns of radiating elements, a first beamforming network that is coupled between a first subset of the RF ports and a first antenna array that comprises a first subset of the columns of radiating elements, and a second beamforming network that is coupled between a second subset of the RF ports and a second antenna array that comprises a second subset of the columns of radiating elements. The first beamforming network and the first antenna array are configured to generate a first plurality of antenna beams that provide coverage to a first side of a sector of a cell of a cellular communications system but not to a second side of the sector, and the second beamforming network and the second antenna array are configured to generate a second plurality of antenna beams that provide coverage to the second side of the sector but not to the first side of the sector.

Abstract: A lensed multi-beam base station antenna may include a plurality of linear arrays of radiating elements, a plurality of reflectors, a sidelobe suppressor, and a lens. Each array may include a plurality of radiating elements (e.g., two or more radiating elements) that extends forwardly from a planar section of a respective reflector. The sidelobe suppressor may comprise radiofrequency (RF) absorber material that absorbs energy that is emitted by a first of the arrays and that is directed toward a reflector underneath a second of the arrays. The sidelobe suppressor may comprise a RF choke that reduces the RF energy emitted by a first of the arrays that is directed toward a reflector underneath a second of the arrays.

Abstract: A base station antenna includes a reflector assembly and a linear array of radiating elements extending forwardly from the reflector assembly. The reflector assembly includes an RF choke that has a choke body and a choke cover. The choke cover at least partially covers a choke body opening so that a choke opening of the RF choke is smaller than the choke body opening.
