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 comprises: a worm gear unit, which is arranged on the first side of the reflector of the base station antenna and includes a worm driven by a motor and a worm gear meshed with the worm; a bevel gear pair unit, which is arranged on the second side of the reflection plate opposite to the first side and includes a first bevel gear and a second bevel gear meshed with each other, wherein the first bevel gear and the worm gear are coaxially installed on a first drive shaft; and at least one rack-and-pinion unit arranged on the second side of the reflection plate, wherein each rack-and-pinion unit includes a third gear and a rack element meshed with each other, all the third gears and the second bevel gears of the at least one rack-and-pinion unit are coaxially installed on a second drive shaft, and each rack element is fixed on the connecting rod of the phase shifter of the base station antenna for driving the connecting rod to move longitudinally. The transmission mechanism not only occupies a small total volume, but can also be installed in different spaces dispersedly, so that it can better adapt to the trend that the inner space of the base station antenna is getting smaller and more dispersed.

Abstract: A base station antenna that may include radiating elements having tilted dipoles. For example, a base station antenna may include a reflector and a plurality of radiating elements, each radiating element mounted on the front surface of the reflector and having a support stalk and at least one dipole mounted to the support stalk. The radiating elements include a plurality of first radiating elements configured to operate in a first operating frequency band, and arranged in one or more first columns extending along a first direction; and a plurality of second radiating elements, configured to operate in a second operating frequency band different from the first operating frequency band, and arranged in one or more second columns extending along the first direction. At least one dipole of a first of the second radiating elements in at least one of the second columns is tilted around the first direction.

Abstract: Base station antennas comprise a multi-column, multiband beamforming array that includes a first sub-array of first radiating elements, a second sub-array of second radiating elements and a third sub-array of third radiating elements. The first radiating elements are configured to operate in a first frequency band, the second radiating elements are configured to operate in a second frequency band, and the third radiating elements are configured to operate in both the first frequency band and the second frequency band. Each of the first through third sub-arrays has the same number of columns. A width of the first sub-array exceeds a width of the third sub-array, and a width of the third sub-array exceeds a width of the second sub-array.
