Foldable electronic device

A foldable electronic device, wherein the electronic device comprises an antenna apparatus, a first body, a second body, and a rotating shaft, the first body and the second body are respectively disposed on two sides of the rotating shaft and are rotatively connected to the rotating shaft, the first body comprises a first ground plane, and the second body comprises a second ground plane, and wherein the antenna apparatus comprises:

• a first radiator, disposed on the first body, wherein the first radiator is provided with a ground end and a first open end, the ground end is coupled to the first ground plane, and the first radiator comprises a first feeding point;
• a first feeding circuit, coupled to the first radiator through the first feeding point, and configured to feed a signal of a first operating frequency band to the first radiator, wherein the first radiator is configured to generate a first resonance corresponding to the first operating frequency band;
• a second radiator, disposed on the second body, wherein the second radiator is provided with a second open end, a third open end, and a first ground point located between the second open end and the third open end, the first ground point is coupled to the second ground plane, a ratio of a length of the second radiator between the second open end and the third open end to a length of the first radiator between the ground end and the first open end is greater than 1 and less than or equal to 2, and the second radiator comprises a second feeding point;
• a second feeding circuit, coupled to the second radiator through the second feeding point, and configured to feed a signal of a second operating frequency band to the second radiator, wherein the second radiator is configured to generate a second resonance corresponding to the second operating frequency band, and the second operating frequency band is the same as or adjacent to the first operating frequency band;
• and
• a first tuning circuit, wherein one end of the first tuning circuit is coupled to the second radiator, the other end is coupled to the second ground plane, and the first tuning circuit is configured to adjust the second resonance of the second radiator to correspond to the second operating frequency band, and
• wherein when the electronic device is in a folded state, projections of the first open end and the second open end at least partially overlap in a thickness direction of the electronic device, and a projection of the ground end is located between a projection of the third open end and the projection of the second open end.
