Abstract: The present invention relates to a transmission mechanism for abase station antenna, and abase station antenna including the transmission mechanism. The transmission mechanism includes: a worm gear unit, which includes a worm driven by a motor and a worm gear meshed and connected with the worm; at least one gear pair, each gear pair including a small gear and a large gear that mesh with each other, the small gear and the worm gear being mounted on a common first drive shaft so that the small gear and the worm gear rotate synchronously; and at least one connecting rod, each connecting rod including a first rack element fixedly mounted thereon, wherein the large gear of each gear pair is meshed and connected with the first rack element on a corresponding connecting rod so as to axially move the connecting rod via the first rack element when the large gear of each gear pair rotates.
