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: 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 radiator assembly for a base station antenna has a longitudinal central axis and two dipoles cross-arranged around the longitudinal central axis. Each dipole has two dipole arms and each dipole arm is equipped with a hook-like feeder made of a metal sheet and having a free end portion. The hook-like feeder is capacitively coupled with an associated dipole arm. The radiator assembly is compact and is easy to manufacture and assemble.

Abstract: Antenna arrays include a first plurality of radiating elements in a first column thereof, which are responsive to a first plurality of RF feed signals derived from a first radio, and a second plurality of radiating elements in a second column thereof, which are responsive to a second plurality of RF feed signals derived from a second radio. A power divider circuit is provided, which is configured to drive a first one of the radiating elements at a first end of the second column of radiating elements with a majority of the energy associated with a first one of the first plurality of RF feed signals, and drive a first one of the radiating elements at a first end of the first column of radiating elements with a non-zero minority of the energy associated with the first one of the first plurality of RF feed signals.
