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.

Abstract: An integrated base station antenna comprises a passive antenna that includes a front radome, a matching dielectric layer and a rear radome; and an active antenna mounted on the back of the passive antenna. A distance between the rear radome of the passive antenna and the matching dielectric layer is a first distance, and the distance between the active antenna and the rear radome of the passive antenna is a second distance, where the first distance is selected as 0.25+n/2 times the equivalent wavelength, where n is a positive integer, and the second distance is selected as 0.25+N/2 times the equivalent wavelength, where N is a natural number. The equivalent wavelength is within the range of 0.8 to 1.2 times of the wavelength corresponding to a center frequency of an operating frequency band of the radiating elements in the active antenna.
