Abstract: A base station antenna includes first and second arrays that include respective pluralities of first and second radiating elements arranged along the longitudinal direction of the base station antenna, the second array transversely adjacent the first array. A longitudinal position of each second radiating element is staggered from that of the corresponding first radiating element. The first array comprises first and second sub-arrays, each of which comprises one or a plurality of adjacent first radiating elements. A phase center of the combination of the first and second subarrays is basically aligned with a sub-phase center of the second array

Abstract: Base station antennas include a reflector, a first array of cross-polarized radiating elements that are mounted to extend forwardly from the reflector, and a parasitic assembly. The parasitic assembly includes a base that is mounted on the reflector, a horizontal component shaping element, and a forwardly projecting member that projects forwardly from the base that is coupled between the base and the horizontal component shaping element. The horizontal component shaping element may extend substantially parallel to a plane defined by the reflector and may include a proximate side that is directly connected to the forwardly projecting member and a distal side that is opposite the proximate side. The distal side of is only electrically connected to the reflector through the proximate side.

Abstract: Base station antennas include a first array of radiating elements that is coupled to a first RF port through a first feed network, a second array of radiating elements that is coupled to a second RF port through a second feed network, and first and second circuit elements. The first circuit element has a first port coupled to the first feed network, a second port coupled to a first port of the second circuit element and a third port coupled to a first radiating element of the first array of radiating elements. The second circuit element has a second port coupled to a first radiating element of the second array of radiating elements and a third port coupled to the second feed network.
