Title:
FOLDABLE ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/060479
Kind Code:
A1
Abstract:
Provided in the present application is a foldable electronic device. The foldable electronic device comprises two main bodies which can be open and closed relative to each other, and a main antenna unit and a parasitic antenna unit, which are respectively arranged on the two main bodies. The main antenna unit comprises a radiation branch and a grounding port arranged between two tail ends of the radiation branch. The parasitic antenna unit comprises a parasitic branch and a ground return port, and the ground return port is arranged on the parasitic branch and is close to one end portion of the parasitic branch or is located on the end portion. The parasitic branch and the radiation branch are arranged in an overlapping manner when the electronic device is in a folded state. When the electronic device is in a folded state and a main antenna unit performs feeding, the main antenna unit is coupled to the parasitic antenna unit, such that a current generated on the parasitic branch is in the same direction as a current generated in at least part of the area of the radiation branch, so that the radiation energy loss of the radiation branch can be reduced by means of the currents superimposed in the same direction, and thus the radiation efficiency of the main antenna unit can be improved in the folded state, so as to improve the communication performance of the electronic device.
