Abstract: This disclosure provides an antenna system. The antenna system includes a first antenna and a second antenna. The first antenna includes a first radome, a first radiating assembly, and a feed network. The second antenna includes a second radome and a second radiating assembly. The first radome has a first outer surface. The first outer surface has a groove. The feed network is disposed on a side part of the groove, and the feed network is disposed in the first radome and is connected to the first radiating assembly. The second radome has a second outer surface, the second radiating assembly is disposed in the second radome, and at least a part of the second outer surface extends into the groove. In the antenna system provided in this disclosure, when the first antenna and the second antenna are used in combination, a thickness size is not significantly increased.

Abstract: This application provides an antenna downtilt adjustment apparatus, including: a first transmission assembly, a flexible transmission assembly, and a second transmission assembly that are disposed on a mounting plate. The flexible transmission assembly includes a transmission element and a guiding element. The transmission element is in an integrated long strip shape and bendable. One end of the transmission element mates with the first transmission assembly, and the other end of the transmission element mates with the second transmission assembly. The guiding element is secured to the mounting plate, and the guiding element is configured to constrain an extension path of the transmission element on the mounting plate. The first transmission assembly is driven by an antenna information management module, and transmits a force to the second transmission assembly by using the transmission element. The second transmission assembly is configured to drive a phase shifter, to adjust an antenna downtilt.
