    Abstract: A base station antenna includes a first reflector structure that extends along a first longitudinal axis, the first reflector structure having a first transverse cross-section, a second reflector structure that extends along a second longitudinal axis, the second reflector structure having a second transverse cross-section that is different from the first transverse cross-section, and the second reflector structure extending above the first reflector structure, a first array of first frequency band radiating elements that are mounted to extend outwardly from the first reflector structure, a second array of second frequency band radiating elements that are mounted to extend outwardly from the second reflector structure, the first frequency band being non-overlapping with the second frequency band, and a radome that extends around the first reflector structure and the second reflector structure.

    Abstract: A small cell cellular base station includes an eight port radio and an eight-port base station antenna that has four linear arrays of dual-polarized radiating elements. Each of the linear arrays has a different azimuth boresight pointing direction and each dual-polarized radiating element includes first and second radiators that have respective directional radiation patterns. The radio is configured to determine and apply a first set of amplitude and phase weights to RF signals that are received through the eight ports of the antenna, and to apply a second set of amplitude and phase weights to RF signals that are output by the radio to the eight ports of the antenna.

    Abstract: A dipole antenna includes a planar reflector and a radiating element. The radiating element includes first and second pairs of dipoles on a surface of the planar reflector. The first and second pairs of dipoles respectively include arm segments arranged around a central region in a box dipole arrangement. The arm segments may be printed circuit board portions having respective metal segments and respective inductor-capacitor circuits thereon. The inductor-capacitor circuits define a filter aligned to a frequency range higher than an operating frequency range of the first and second pairs of dipoles.

    Abstract: A feed network for use with an antenna array includes at least first and second RF inputs, a combiner network and a beamforming network. In some examples, additional RF inputs are provided. Each RF input corresponds to a sub-band. The first RF input for a first sub-band signal is coupled to a first sub-band parameter control; the second RF input for the second sub-band signal is coupled to a second sub-band parameter control. The combiner network is coupled to the first sub-band parameter control and to the second sub-band parameter control. The combiner network also has at least one output comprising a combination of the first sub-band signal and the second sub-band signal. The beamforming network is coupled to the combiner network and has a plurality of RF outputs. The first and second sub-band parameter controls are independently adjustable. In one example, the beamforming network comprises a Butler matrix.
