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.
