Abstract: The electronic device includes a composite antenna including a slot antenna and a wire antenna. A first strip-shaped conductor of the slot antenna includes a first ground part, a second ground part, and a feeding part. The first ground part and the second ground part are respectively two ends of the first strip-shaped conductor. The feeding part is located between the first ground part and the second ground part. A second strip-shaped conductor of the wire antenna includes a first end and a second end. The first end of the second strip-shaped conductor is electrically connected to the first ground part. The second end of the second strip-shaped conductor is an open end.

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.

Abstract: An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.
