Abstract
This application provides a foldable electronic device, including two main bodies that are capable of being relatively folded or unfolded and a main antenna unit and a parasitic antenna unit that are respectively disposed on the two main bodies. The main antenna unit includes a radiation stub and a ground port disposed between two ends of the radiation stub. The parasitic antenna unit includes a parasitic stub and a ground return port, and the ground return port is disposed on the parasitic stub and is close to or located at one of end portions of the parasitic stub. When the electronic device is in a folded state, the parasitic stub overlaps the radiation stub.

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,
- wherein both the first end and the second end of the radiation stub of the main antenna unit are open-circuit ends;
- and
- when the electronic device is in the folded state, the first end portion of the parasitic stub is disposed opposite to the first end of the radiation stub, and the second end portion of the parasitic stub is disposed opposite to the second end of the radiation stub.
