Abstract: A base station antenna includes a plurality of antenna arrays and a phase dispersion circuit. The plurality of antenna arrays include a plurality of radiating elements, and the plurality of radiating elements include a first radiating element and a second radiating element that have a horizontal spacing. The phase dispersion circuit is configured to adjust a phase slope of an electromagnetic signal of the first radiating element in an operating frequency band and/or a phase slope of an electromagnetic signal of the second radiating element in the operating frequency band.
