    Abstract: The present disclosure relates to an antenna assembly, which comprises: a feeder panel; an array of radiating elements mounted on the feeder panel; an array of parasitic elements mounted on the feeder panel, in which, at least a portion of the radiating elements in the array of radiating elements are surrounded by a plurality of spaced-apart parasitic elements, respectively, and at least a portion of the parasitic elements in the array of parasitic elements each comprise a first parasitic subcomponent extending in a first direction and a second parasitic subcomponent extending in a second direction perpendicular to the first direction. In addition, the present disclosure also relates to a base station antenna comprising the antenna assembly. This is capable of effectively improving the cross-polarization performance of the base station antenna and improving the radiation boundary of the base station antenna.

    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.

    Abstract: Base station antennas comprise a planar reflector, a radiating element mounted to extend forwardly from the planar reflector, the radiating element including a dipole that comprises an inner dipole arm and an outer dipole arm, and a radome having a front wall, a side wall and a curved front transition wall that connects the front wall to the side wall. A distal end of the outer dipole arm is closer to the planar reflector than is a base of the outer dipole arm, and an overlap portion of the outer dipole arm overlaps the curved front transition wall. A largest minimum distance between any point on a front surface of the overlap portion of the outer dipole arm and the radome is less than twice a smallest minimum distance between any point on the front surface of the overlap portion of the outer dipole arm and the radome.

    Abstract: A radiating element includes a feed rod and a radiator mounted on the feed rod. The radiator includes a dielectric substrate, a first dipole arranged along a first axis and including a first dipole arm and a second dipole arm, and a second dipole arranged along a second axis perpendicular to the first axis and including a third dipole arm and a fourth dipole arm. Each dipole arm includes a closed conductive segment provided on the dielectric substrate and conductive patches are respectively provided on the dielectric substrate within boundaries defined by the closed conductive segment of each dipole arm. The dielectric substrate with the closed conductive segments and conductive patches constitutes a frequency selective surface which is configured to allow radiation in a frequency range higher than the operating frequency range of the radiating element to pass.

    Abstract: A base station antenna includes a backplane and a plurality of radiating elements that extend forwardly from the backplane. The antenna further includes a plurality of feed boards, and each of the feed boards has a respective group of one or more of the radiating elements mounted thereon. The antenna also includes a calibration port and a calibration circuit that has a calibration combiner that has an output that is coupled to the calibration port and a plurality of directional couplers that are coupled to the calibration combiner. At least a first portion of a first of the first directional couplers is implemented on a first of the feed boards.

    Abstract: An antenna includes a first column of main radiating elements, each main radiating element configured to operate in a first operating frequency band and a first auxiliary radiating element. The first auxiliary radiating element is adjacent a first main radiating element in the first column of main radiating elements, and the first auxiliary radiating element is configured to radiate an electromagnetic wave that is substantially antiphase to an electromagnetic wave radiated by the first main radiating element.
