摘要： Embodiments of this application provide an antenna apparatus and an electronic device. A primary screen portion of the electronic device is designed with a primary-screen antenna, and a secondary screen portion of the electronic device is designed with a secondary-screen antenna. The primary-screen antenna and the secondary-screen antenna may be antennas that operate on a same frequency band, and positions of the primary-screen antenna and the secondary-screen antenna overlap when a foldable screen is in a folded state. 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, and radiation patterns of the primary-screen antenna and the secondary-screen antenna are complementary. This is especially beneficial to a MIMO antenna design of an electronic device having a foldable screen. In addition, two or more antennas that operate on a same frequency band can be highly isolated from each other without isolating a plurality of antennas that operate on a same frequency band at physical positions. For example, the plurality of antennas do not need to be staggered at physical positions. This fully utilizes an antenna design space of the electronic device having a foldable screen.

摘要： This application discloses a foldable electronic device, including 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 the ground of the second device body, and the other end is connected to the first parasitic radiator. In this application, in the folded state, antenna performance in a free space scenario or a handheld scenario can be improved, and antenna performance of the antenna located on a top portion in a head-hand holding scenario can also be improved.

摘要： This application provides an antenna and a mobile terminal. The antenna may include the following structures: a main stub, a first parasitic stub, and/or 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. During specific connection, the first parasitic stub is coupled to the main stub by electric field coupling, and a frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. The second parasitic stub is coupled to the main stub by electric field and magnetic field coupling, and a frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub. In the foregoing technical solution, the first parasitic stub and the second parasitic stub are coupled to the main stub in an electric field coupling manner or an electric field and magnetic field coupling manner, to excite a resonance to improve antenna efficiency, expand bandwidth, and improve antenna performance.

摘要： This application provides an electronic device. The electronic device includes a radio frequency front-end and an antenna unit. The antenna unit includes an antenna body, the antenna body has a feed point and a ground point, the antenna body includes a first end and a second end, no gap is configured on the antenna body, the feed point is configured to connect to the radio frequency front-end, and the ground point is configured to connect to a ground of the electronic device.

摘要： In the antenna solution provided in this application, an exciting element is disposed above a ground plane of an electronic device (for example, a mobile phone), to feed power to the exciting element, so as to effectively excite the ground plane to generate radiation. In this way, because a radiation capability of the ground plane is not affected by a size of a clearance between a display screen and the ground plane, the antenna solution provided in this application is applicable to a bezel-less electronic device whose antenna space is sharply reduced. In addition, the ground plane serves as one of the main radiation apertures of an electronic device (for example, a mobile phone), and exciting the ground plane to generate radiation can significantly improve antenna performance.
