    Abstract: An antenna assembly includes a backplane and a polymer substrate mounted over the backplane to define an air gap there-between. The polymer substrate supports radiating elements comprising a polymer-based waveguide feed stalk and a polymer-based pair of radiating arms supported by and electrically coupled to the waveguide feed stalk. A conductive layer is formed on the polymer substrate such that the conductive layer faces the backplane. A phase shifter including a movable element such as a dielectric member r trombone member may be positioned in the air gap for adjusting the phase of a radiating element or a phase shifter assembly may be positioned to the back side of the back plane.

    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.
