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: 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.
