This application provides an antenna and an electronic device. The antenna includes at least two radiators. The at least two radiators include a first radiator and a second radiator that are spaced apart in parallel, and a first end of the first radiator is disposed closer to a first end of the second radiator than a second end of the first radiator. Both the first radiator and the second radiator are connected to a feed point. Both the first end of the first radiator and the first end of the second radiator are grounded. A gap by which the first radiator and the second radiator are spaced part is less than or equal to 3 mm.
