摘要： This application relates to an antenna and an electronic device. The antenna includes a patch radiator, a first ground point, and a second ground point. The patch radiator has a first side edge and a second side edge that intersect with each other, and has a first coupling contact and a second coupling contact. The patch radiator is coupled to the first ground point and the second ground point through the first coupling contact and the second coupling contact, to be grounded through the first ground point and the second ground point. The first coupling contact and the second coupling contact are disposed on the patch radiator at an interval, and a distance between the first coupling contact and the first side edge, a distance between the first coupling contact and the second side edge, a distance between the second coupling contact and the first side edge, and a distance between the second coupling contact and the second side edge are all greater than or equal to 0.05λ. According to a manner of disposing a ground point in this application, currents on the patch radiator can be evenly distributed around, to form an omnidirectional pattern. This reduces a directivity coefficient, and enables the antenna to have features such as a low SAR and high efficiency.

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 an electronic device that includes the antenna. The antenna includes an antenna body and a feed point and a grounding point that are located on the antenna body. The antenna body includes a first section and a second section that intersect with each other. An electrical length between the feed point and a first end of the antenna body is greater than an electrical length between the feed point and a second end opposite to the first end. The antenna body generates resonance of a second wavelength in a quarter wavelength mode between the feed point and the first end, and the antenna body generates resonance of the second wavelength in a half wavelength mode between the first end and the second end. In this application, mode excitation generated based on the resonance of the second wavelength in the quarter wavelength mode can be enhanced by using the resonance of the second wavelength in the half wavelength mode, so that horizontal mode excitation and vertical mode excitation of the antenna are relatively balanced. Therefore, the antenna can have relatively good radiation performance regardless of whether the electronic device is in free space (FS) or in a handheld state.

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.
