Abstract: A foldable electronic device having a primary screen portion with a primary-screen antenna, and a secondary screen portion with a secondary-screen antenna. Positions of the primary-screen antenna and the secondary-screen antenna overlap when the electronic device is folded. The primary-screen antenna and the secondary-screen antenna may excite two antenna patterns of high isolation. In this way, even if the primary-screen antenna and the secondary-screen antenna operate on a same frequency band and overlap, good isolation performance can also be obtained.

Abstract: An electronic device includes an antenna unit having an antenna body having a feed point and a ground point between a first end and a second end. The antenna body has an operating band with a resonance of a first wavelength. An electrical length of the antenna body from the feed point to the ground point is greater than or equal to ¼ and less than ½ of the first wavelength. An electrical length from the first end to the feed point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. An electrical length from the second end to the ground point is greater than or equal to ⅛ and less than or equal to ¼ of the first wavelength. The antenna body is adapted to operate in a slot mode and in a wire mode.

Abstract: An antenna has an exciting element disposed above a ground plane of an electronic device. Power fed to the exciting element excites the ground plane to generate radiation. In this way, radiation capability of the ground plane is not affected by clearance between a display screen and the ground plane, and the antenna is applicable to an electronic device with limited antenna space. In addition, the ground plane serves as a radiation aperture of the electronic device.

Abstract: An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.

Abstract: A foldable electronic device includes a first device body, a second device body, an earpiece, an antenna, and a first switch control circuit. The antenna includes a main radiator and a first parasitic radiator. The main radiator is disposed on the first device body, and the first parasitic radiator and the earpiece are disposed on the second device body. When the foldable electronic device is in a folded state, the main radiator is disposed relative to the first parasitic radiator at a first interval and is coupled to the first parasitic radiator through the first interval. The first switch control circuit includes a first switch component and a plurality of different first matching branches disposed in parallel connection. One end of the first switch control circuit is connected to a ground of the second device body, and the other end is connected to the first parasitic radiator.
