Abstract
A base station antenna comprises a reflector, a plurality of first radiating elements arranged in a first column that extends in a vertical direction, a plurality of second radiating element arranged in a second column that extends in the vertical direction, and a plurality of parasitic elements, where the parasitic elements are arranged around the first radiating elements and/or second radiating elements. Each parasitic element is configured as a rod-shaped metal part, where a longitudinal axis of the rod-shaped metal part extends at an angle of between 70° to 110° with respect to a plane defined by the reflector, and the parasitic elements are positioned in front of the reflector in and are electrically floating with respect to the reflector.
