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.
Claims18
An antenna, comprising:
- a first reflective surface;
- N feeds disposed on the first reflective surface;
- and
- N second reflective surfaces,
- wherein N is an integer greater than 1,
- wherein the first reflective surface comprises N areas,
- wherein the N areas are in one-to-one correspondence with the N feeds,
- wherein the N second reflective surfaces are in one-to-one correspondence with the N feeds, and each of the N second reflective surfaces is configured to reflect, to one of the N areas, a beam radiated by a corresponding one of the N feeds,
- wherein each of the N areas is configured to reflect a beam from a corresponding one of the N second reflective surfaces, and
- wherein a virtual focus of each of the N second reflective surfaces coincides with a real focus of the first reflective surface.
An antenna system, comprising:
- a plurality of antennas,
- wherein a first antenna of the plurality of antennas comprises a first reflective surface, N second reflective surfaces, and N feeds, and N is an integer greater than 1,
- wherein the N feeds are disposed on the first reflective surface,
- wherein the first reflective surface comprises N areas,
- wherein the N areas are in one-to-one correspondence with the N feeds,
- wherein the N second reflective surfaces are in one-to-one correspondence with the N feeds, and each of the N second reflective surfaces is configured to reflect, to one of the N areas, a beam radiated by a corresponding one of the N feeds,
- wherein each of the N areas is configured to reflect a beam from a corresponding one of the N second reflective surfaces, and
- wherein a virtual focus of each of the N second reflective surfaces coincides with a real focus of the first reflective surface.
