Foldable electronic device

A foldable electronic device, comprising:

• a first body and a second body, wherein the first body and the second body are connected to each other and are capable of being relatively folded or unfolded;
• a main antenna unit, disposed on the first body, wherein the main antenna unit comprises a radiation stub, a feeding port, and a ground port, and the feeding port is configured to feed the radiation stub;
• and the radiation stub comprises a first end and a second end, and the ground port is disposed between the first end and the second end of the radiation stub;
• and
• a parasitic antenna unit, disposed on the second body, wherein the parasitic antenna unit comprises a parasitic stub and a ground return port, the parasitic stub comprises a first end portion and a second end portion, and the ground return port is disposed on the parasitic stub and is close to or located at one of the end portions of the parasitic stub;
• and when the electronic device is in a folded state, the parasitic stub overlaps the radiation stub;
• wherein
• when the electronic device is in the folded state and the main antenna unit performs feeding, the main antenna unit is coupled to the parasitic antenna unit, so that a current generated on the parasitic stub is in a same direction as a current generated in at least some areas of the radiation stub;
• and
• a resonance frequency of the parasitic antenna unit is less than a resonance frequency of the main antenna unit.
