1. An electronic device, comprising:
a first body, comprising:
a first housing comprising a metal part, and a non-metal part disposed on one side of the first housing;
a second housing connected to the first housing, wherein a material of the second housing is metal, the second housing comprises a heat-dissipating vent area corresponding to a position of the non-metal part, and the heat-dissipating vent area comprises a plurality of metal bars and a plurality of air outlets formed between the metal bars;
a metal wall disposed between the first housing and the second housing and located adjacent to the non-metal part and the heat-dissipating vent area, wherein the non-metal part, the metal wall, and the heat-dissipating vent area define a cavity; and
an antenna module disposed in the cavity and comprising a first antenna layer, wherein the first antenna layer comprises a feeding end, a first radiator extending from the feeding end, and a second radiator extending from the feeding end in a direction away from the first radiator,
wherein the first radiator and the second radiator of the antenna module are configured to resonate at a first frequency band and a second frequency band, respectively, a length of the first radiator is ¼ wavelength of the first frequency band, and a length of the second radiator is ¼ wavelength of the second frequency band,
wherein a length of the heat-dissipating vent area is between 0.35 times wavelength and 0.5 times wavelength of the first frequency band,
wherein the antenna module comprises a second antenna layer stacked on the first antenna layer and attached to the first housing, and a coupling distance between the first antenna layer and the second antenna layer is between 0.4 mm and 1 mm, and the antenna module comprises an insulating layer sandwiched between the first antenna layer and the second antenna layer, and the coupling distance is a thickness of the insulating layer.
