Abstract: Embodiments of this application provide an antenna and an antenna system. As the antenna is functionally equivalent to a plurality of conventional antennas, device costs and base station space occupied by the antenna can be reduced. The antenna includes a first reflective surface and N feeds, where N is an integer greater than 1. The N feeds are disposed on the first reflective surface, the first reflective surface includes N areas, the N areas are in one-to-one correspondence with the N feeds, and each area is used to reflect a beam radiated by a corresponding feed.
