1. A base station antenna, comprising:
a first array that includes a plurality of sub-arrays of first radiating elements, where each sub-array of first radiating elements is on a respective first feed board, the plurality of sub-arrays of first radiating elements arranged along a longitudinal direction of the base station antenna; and
a second array that includes a plurality of sub-arrays of second radiating elements, where each sub-array of second radiating elements is on a respective second feed board, the plurality of sub-arrays of second radiating elements arranged along the longitudinal direction of the base station antenna,
wherein a phase center of a first of the sub-arrays of first radiating elements is not aligned with respective phase centers of any of the sub-arrays of second radiating elements, and
wherein a phase center of a combination of a first of the sub-arrays of first radiating elements and a second of the sub-arrays of first radiating elements is aligned with a phase center of a combination of a first of the sub-arrays of second radiating elements and a second of the sub-arrays of second radiating elements.
