Abstract
An electronic device comprises a first radiator coupled to a second radiator. One end of a second branch of the second radiator is connected between a head end and a tail end of a first branch of the second radiator. The other end of the second branch is connected between a head end and a tail end of a third branch of the second radiator. A projection of a reference face of the first branch on the first radiator is a first projection. The first projection partly overlaps the first radiator, or a distance between the first projection and the first radiator is within a range of 0 to 3 millimeters. A ratio of a first center distance between an end face of the third branch and the reference face, and a second center distance between the other end face of the third branch and the reference face is within a range of 0.5 to 2.
