Abstract: Base station antennas comprise a multi-column, multiband beamforming array that includes a first sub-array of first radiating elements, a second sub-array of second radiating elements and a third sub-array of third radiating elements. The first radiating elements are configured to operate in a first frequency band, the second radiating elements are configured to operate in a second frequency band, and the third radiating elements are configured to operate in both the first frequency band and the second frequency band. Each of the first through third sub-arrays has the same number of columns. A width of the first sub-array exceeds a width of the third sub-array, and a width of the third sub-array exceeds a width of the second sub-array.

Abstract: A base station antenna (BSA) includes a reflector having a main reflector surface thereon, which extends between first and second sidewalls thereof. First and second choke-within-a-choke assemblies are provided on first and second sides of the reflector, respectively. The first choke-within-a-choke assembly includes: a first relatively low-band choke defined on one side thereof by the first sidewall of the reflector, and a first relatively high-band choke contacting on two sides thereof a rear surface of the reflector and an inner surface of the first sidewall. The second choke-within-a-choke assembly includes: a second relatively low-band choke defined on one side thereof by the second sidewall of the reflector, and a second relatively high-band choke contacting on two sides thereof the rear surface of the reflector and an inner surface of the second sidewall.

Abstract: Radiating elements include a first and second dipole arms that extend along a first axis and that are configured to transmit RF signals in a first frequency band. The first dipole arm is configured to be more transparent to RF signals in a second frequency band than it is to RF signals in a third frequency band, and the second dipole arm is configured to be more transparent to RF signals in the third frequency band than it is to RF signals in the second frequency band. Related base station antennas are also provided.

Abstract: A cross-dipole radiating element includes first and second polymer-based coplanar waveguide feed stalks, and first and second pairs of polymer-based radiating arms, which are supported by and electrically coupled to the first and second coplanar waveguide feed stalks. These polymer-based feed stalks and radiating arms are configured as a unitary polymer substrate, which is selectively metallized to define a cross-dipole radiating element. The first and second feed stalks may be configured as finite grounded coplanar waveguide (GCPW) feed stalks, which are spaced-apart from each other on an underlying polymer base. The unitary polymer substrate may include the polymer base.

Abstract: Base station antennas include a main module that has a first backplane that includes a first reflector. A vertically-extending array of first radiating elements is mounted to extend forwardly from the first reflector, and at least one first RF port is coupled to the vertically-extending array of first radiating elements. These antennas further include a sub-module that is attached to the first backplane. The sub-module includes a second backplane that has a second reflector that is separate from the first reflector. A vertically-extending array of second radiating elements is mounted to extend forwardly from the second reflector and is transversely spaced-apart from the vertically-extending array of first radiating elements. A plurality of second RF ports are coupled to the vertically-extending array of second radiating elements. The vertically-extending array of first radiating elements and the vertically-extending array of second radiating elements are configured to serve a common sector of a base station.

Abstract: An antenna includes a cross-polarized feed signal network configured to convert first and second radio frequency (RF) input feed signals to first and second pairs of cross-polarized feed signals at respective first and second pairs of feed signal output ports. A feed signal pedestal is provided, which is electrically coupled to the first and second pairs of feed signal output ports, and a patch radiating element is provided, which is electrically coupled by the feed signal pedestal to the first and second pairs of feed signal output ports. This patch radiating element may be capacitively coupled to first and second pairs of feed signal lines on the feed signal pedestal, which are electrically connected to the first and second pairs of feed signal output ports.
