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.

Abstract: A patch radiating element that includes a feeder pillar and a patch radiator mounted on the feeder pillar. The patch radiator includes a first patch portion extending in a first direction and a second patch portion extending from an outer end portion of the first patch portion in a second direction. The second direction is different from the first direction. As a result, a space interval between adjacent patch radiating elements can be increased, thereby improving the isolation between the adjacent patch radiating elements so that beamforming of an antenna can be optimized.
