摘要： An antenna apparatus includes a feeding antenna inside an electronic device and one or more antenna elements, such as a floating metal antenna, disposed on a rear cover of the electronic device. The floating metal antenna and a feeding antenna inside the electronic device may form a coupling antenna structure. The feeding antenna may be an antenna fastened on an antenna support (which may be referred to as a support antenna). The feeding antenna may alternatively be a slot antenna formed by slitting on a metal middle frame of the electronic device. The antenna apparatus may be implemented in limited design space, thereby effectively saving antenna design space inside the electronic device. The antenna apparatus may generate excitation of a plurality of resonance modes, so that antenna bandwidth and radiation characteristics can be improved.

摘要： This application discloses an antenna for a foldable electronic device and a foldable electronic device. The foldable electronic device includes a first housing and a second housing that are rotationally connected to each other by means of rotating shafts located on two sides, and an antenna. The first housing can switch between an unfolded state and a folded state relative to the second housing, and the antenna is disposed in a closed slot. The antenna is an antenna of a three-dimensional structure. The antenna includes a first antenna segment and a second antenna segment that are sequentially connected and disposed in a length direction of the antenna. In the unfolded state, the second antenna segment is located below the first antenna segment. One end of the first antenna segment is connected to a ground plate of the first housing. The first antenna segment extends from one end toward a direction in which an opening/closing region of the first housing and the second housing in the unfolded state is away from the first housing. There is a gap between an end of the second antenna segment and the ground plate of the first housing. A radio frequency signal output by a radio frequency module is received by means of the second antenna segment. This application can effectively optimize directivity of the antenna.

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.
