1. An electronic device, comprising a first device body, a second device body, and a rotating shaft, wherein the first device body and the second device body are connected through the rotating shaft, and the electronic device is configured to be foldable at the rotating shaft; and
the electronic device further comprises a first antenna disposed on the first device body and a second antenna disposed on the second device body, wherein
the first antenna comprises a strip-shaped first conductor and a first feed point disposed on the first conductor, wherein two ends of the first conductor are open, and a distance from the first feed point to a middle position of the first conductor is greater than or equal to zero and less than 1/16 of an operating wavelength of the first antenna, or a distance from the first feed point to one of the open ends of the first conductor is greater than or equal to zero and less than 1/16 of an operating wavelength of the first antenna; and
the second antenna is an inverted F antenna that comprises a strip-shaped second conductor, and a second feed point and a grounding stub that are disposed on the second conductor, wherein one end of the second conductor is open, the other end of the second conductor is grounded through the grounding stub, and a distance from the second feed point to a connection point for the second conductor and the grounding stub is greater than zero and less than ⅛ of an operating wavelength of the second antenna, or a distance from the second feed point to the open end of the second conductor is greater than or equal to zero and less than ⅛ of an operating wavelength of the second antenna, wherein the first conductor and the second conductor at least partially overlap when the electronic device is in a folded state.
