Abstract
Provided is an electronic device. A radiator is provided on a first side edge of a frame. At least one resonant structure is provided on at least one of a side where a top edge is located, a side where the first side edge is located and a side where a second side edge is located. A direction from a first ground terminal to a first free end of the radiator is the same as or does not intersect with a direction from a second ground terminal to a second free end of the resonant structure. A signal source excites the radiator to operate in a first resonant mode supporting a first frequency band, and excites a reference ground plate to generate a ground plate current. The resonant structure operates in a second resonant mode supporting a second frequency band at least under excitation of the ground plate current.

An electronic device, comprising:
- a reference ground plate comprising a first ground plate edge, a second ground plate edge, a third ground plate edge and a fourth ground plate edge connected in sequence;
- a frame surrounding a periphery of the reference ground plate, wherein the frame comprises a top edge, a first side edge, a bottom edge and a second side edge which are connected, the top edge is opposite to and spaced apart from the first ground plate edge, the first side edge is opposite to and spaced apart from the second ground plate edge, the bottom edge is opposite to and spaced apart from the third ground plate edge, and the second side edge is opposite to and spaced apart from the fourth ground plate edge;
- and
- an antenna assembly comprising:
- a radiator provided on the first side edge, wherein the radiator comprises a first ground terminal, a feed point and a first free end arranged in sequence, and the first ground terminal is electrically connected to the reference ground plate;
- a signal source electrically connected with the feed point;
- and
- at least one resonant structure provided on at least one of a side where the top edge is located, a side where the first side edge is located, and a side where the second side edge is located, wherein each of the at least one resonant structure comprises a second ground terminal and a second free end, the second ground terminal is electrically connected to the reference ground plate, and a direction from the first ground terminal to the first free end is the same as or does not intersect with a direction from the second ground terminal to the second free end;
- wherein the signal source is configured to excite the radiator to operate in a first resonant mode supporting a first frequency band, and excite the reference ground plate to generate a ground plate current, the at least one resonant structure is configured to operate in a second resonant mode supporting a second frequency band at least under excitation of the ground plate current, and a center frequency of the first frequency band is greater than or equal to a center frequency of the second frequency band.
