Antenna gearbox transmission mechanism and antenna

An antenna, comprising:

• a first antenna array phase shifter;
• a second antenna array phase shifter;
• and
• an antenna gearbox transmission mechanism, wherein the antenna gearbox transmission mechanism comprises:
• a drive shaft;
• a first transmission structure;
• and
• a second transmission structure, wherein
• the first transmission structure comprises a first driving gear and a first driven gear set,
• the second transmission structure comprises a second driving gear and a second driven gear,
• both the first driving gear and the second driving gear are in a transmission connection to the drive shaft,
• the first driven gear set is in a first transmission connection to the first antenna array phase shifter,
• the second driven gear is in a second transmission connection to the second antenna array phase shifter,
• the first driving gear meshes with the first driven gear set,
• the second driving gear has a part without gear teeth and a part with gear teeth, and
• in response to a movement of the second driving gear, the second driving gear meshes with or is not meshed with the second driven gear.

An antenna gearbox transmission mechanism, comprising:

• a drive shaft;
• a first transmission structure;
• and
• a second transmission structure, wherein
• the first transmission structure comprises a first driving gear and a first driven gear,
• the second transmission structure comprises a second driving gear and a second driven gear,
• both the first driving gear and the second driving gear are in a transmission connection to the drive shaft,
• the first driven gear is configured to be connected to a first antenna array phase shifter,
• the second driven gear is configured to be connected to a second antenna array phase shifter,
• both the first driving gear and the second driving gear are racks,
• the first driving gear has opposite first and second sides, and comprises a first rack and a second rack,
• the first rack is arranged on the first side and has gear teeth projecting towards the second rack,
• the second rack is arranged on the second side and has gear teeth projecting towards the first rack,
• the second driving gear comprises a third rack, and
• in response to a rotation of the drive shaft, the first driving gear and the second driving gear move synchronously and linearly between
• a first position where gear teeth of the first rack of the first driving gear mesh with the first driven gear, and gear teeth of the third rack of the second driving gear mesh with the second driven gear, and
• a second position where gear teeth of the second rack of the first driving gear mesh with the first driven gear, and the second driving gear has no gear teeth meshing with the second driven gear.
