1. An antenna, comprising:
a first radiator including a first rotationally symmetric structure; and
a second radiator including a second rotationally symmetric structure,
wherein the first radiator includes two feeding ports that are 90° rotationally symmetric with respect to a geometric center of the first radiator,
wherein the second radiator is annular, the first radiator and the second radiator are coplanar, the first radiator is disposed in the second radiator, and an annular gap is between the first radiator and the second radiator, and
wherein a first operating frequency band of the second radiator comprises a first frequency band, and a second operating frequency band of the annular gap comprises a second frequency band different from the first frequency band to ensure multi-frequency coverage.
