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: Base station antennas include at least one passive internal grid reflector with an array of low band radiating elements projecting forward of a front one of the at least one grid reflector. A mMIMO antenna array resides behind a back one of the at least one grid reflector and is configured to transmit signal through the grid reflector and out a front radome of the base station antenna.

Abstract: An integrated base station antenna comprises a passive antenna and an active antenna installed behind the passive antenna. The active antenna comprises a reflecting plate and an array of radiating elements extending forward from the reflecting plate. The passive antenna includes an array of metal tuning elements that tune the array of radiating elements, where the array of metal tuning elements us positioned in front of the array of radiating elements of the active antenna, and where a longitudinal axis of at least some of the metal tuning elements extend at an angle between 70° and 110° with respect to a plane defined by the reflecting plate.
