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: The present disclosure relates to a transmission mechanism for a base station antenna, and a base station antenna including the transmission mechanism. The transmission mechanism includes a motor and at least one connecting rod, wherein a gear mechanism is provided on a first end of the connecting rod, and the motor drives the connecting rod to rotate via the gear mechanism; and wherein a worm gear unit is provided on a second end of the connecting rod opposite to the first end, and the worm gear unit is configured to drive a movable element of a phase shifter when the connecting rod rotates. The transmission mechanism according to the present disclosure can generate greater driving force through the worm gear unit, and has a shorter axial length and a smaller height, and thus is particularly suitable for a more compact and thinner 5G base station antenna.
