Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a Bypass Continuation application of International Patent Application No. PCT/CN2022/098923, filed Jun. 15, 2022, and claims priority to Chinese Patent Application No. 202110664817.9, filed Jun. 16, 2021, the disclosures of which are hereby incorporated by reference in their entireties. BACKGROUND OF THE INVENTION Field of the Invention The present disclosure relates to the technical field of antennas, and to an electronic device. Description of Related Art With the development of the fifth-generation mobile communication technology, millimeter-wave antennas are gradually applied to small electronic devices such as mobile phones and tablets. However, in a case of maintaining the overall size of an electronic device, increasing a millimeter-wave antenna reduces the effective radiation space allocated to each antenna, thereby affecting the overall radiation performance of the antenna. It can be seen that in the related art, the antenna of the electronic device has the problem of poor radiation performance.
