Abstract: This application discloses an antenna, including a first antenna and a second antenna. The first antenna includes a first radiating element and a reflector. The reflector is located between the second antenna and the first radiating element. The reflector includes a connection part and a tooth part. The tooth part includes a plurality of comb teeth that are disposed side by side and that extend from the connection part toward the first radiating element. A gap is disposed between adjacent ones of the plurality of comb teeth. The tooth part further includes a profile facing the first radiating element. Each comb tooth includes an end part facing the first radiating element. The profile includes a concave part that is concave to the connection part.

Abstract: A printed antenna may include a loop antenna body, a feed port, and a switch component. The loop antenna body includes a first end and a second end, there is a spacing between the first end and the second end, a connection line between the first end and the second end forms a closed loop with the loop antenna body. The feed module is configured to output a feed signal to the loop antenna body by using the feed port. The loop antenna body includes a plurality of loop antenna branches, the switch component is disposed between every two adjacent loop antenna branches, and the switch component is configured to connect or disconnect the two adjacent loop antenna branches.
