    Abstract: Antennas include a first radiating element that is configured to operate in a first operating frequency band, and a second radiating element that is configured to operate in a second operating frequency band that encompasses higher frequencies than the first operating frequency band. The first radiating element includes a first dipole radiator having first and second dipole arms and a second dipole radiator having third and fourth dipole arms. The first dipole arm includes a first metal region that substantially surrounds a first non-metal interior region, and the first non-metal interior region is configured so that currents induced on a first portion of the first metal region by RF energy emitted by the second radiating element substantially cancel currents induced on a second portion of the first metal region by the RF energy emitted by the second radiating element.

    Abstract: A radiating element for a base station antenna includes a first dipole radiator that has a first dipole arm that has a front surface and first and second extensions that project rearwardly from respective side edges of the front surface of the first dipole arm; a second dipole radiator that has a second dipole arm that has a front surface and first and second extensions that project rearwardly from respective side edges of the front surface of the second dipole arm; and a parasitic element having a first conductive segment that is configured to capacitively couple to the first extension of the first dipole arm, a second conductive segment that is configured to capacitively couple to the second extension of the second dipole arm, and a third conductive segment that electrically connects the first conductive segment to the second conductive segment.

    Abstract: A base station antenna includes a radome having a bottom opening, an antenna assembly within the radome, a bottom end cap covering the bottom opening of the radome, the bottom end cap including a plurality of connector receptacles, and a plurality of connectors mounted in respective ones of the connector receptacles, each connector including a connector port that extends downwardly from the bottom end cap. Longitudinal axes of a first subset of the connectors extend at respective oblique angles with respect to a plane that is normal to a longitudinal axis of the antenna.

    Abstract: A multiband radiating array according to the present invention includes a vertical column of lower band dipole elements and a vertical column of higher band dipole elements. The lower band dipole elements operate at a lower operational frequency band, and the lower band dipole elements have dipole arms that combine to be about one half of a wavelength of the lower operational frequency band midpoint frequency. The higher band dipole elements operate at a higher frequency band, and the higher band dipole elements have dipole arms that combine to be about three quarters of a wavelength of the higher operational frequency band midpoint frequency. The higher band radiating elements are supported above a reflector by higher band feed boards. A combination of the higher band feed boards and higher band dipole arms do not resonate in the lower operational frequency band.
