    Abstract: A base station antenna includes a backplane and a plurality of radiating elements that extend forwardly from the backplane. The antenna further includes a plurality of feed boards, and each of the feed boards has a respective group of one or more of the radiating elements mounted thereon. The antenna also includes a calibration port and a calibration circuit that has a calibration combiner that has an output that is coupled to the calibration port and a plurality of directional couplers that are coupled to the calibration combiner. At least a first portion of a first of the first directional couplers is implemented on a first of the feed boards.
