Abstract: An antenna apparatus includes a circuit board and an antenna body. The antenna body includes a first radiator and a second radiator that are indirectly coupled. The first radiator comprises a first stub and a second stub that are opposite to, but do not touch each other to form a first gap, the first stub and the second stub are located on a first side edge of the circuit board, a second gap is configured between the first stub and the first side edge, and also between the second stub and the first side edge. The second radiator is located on the circuit board to form a third gap in-between. A vertical projection of the second radiator is located on the first surface. The first stub and the second stub are electrically connected to reference ground of the circuit board separately.

Abstract: A 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 includes a first antenna segment and a second antenna segment that are sequentially connected and disposed in a length direction of the antenna. 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.

Abstract: An antenna apparatus used in an electronic device having a flexible display that can be bent at a rotating shaft and that includes a primary screen and a secondary screen respectively configured on two sides of the rotating shaft. The antenna apparatus includes a first metal strip disposed on the primary screen frame close to one end of the rotating shaft, and a second metal strip disposed on the secondary screen frame close to the same end of the rotating shaft. The first metal strip is implemented as a plurality of antennas through dual-feed design. When the flexible display is in a folded state, the second metal strip is coupled to the first metal strip to generate radiation and is used as a parasitic antenna of the first metal strip.

Abstract: A mobile terminal and a mobile terminal antenna production method. The mobile terminal uses an insulation film layer on an insulation rear housing as a carrier of a radiating element of an antenna, and the radiating element is located within the entire mobile terminal. A feed and an electric-conductor are disposed on a circuit board, and the electric-conductor is electrically connected to the feed. There is a gap between the radiating element and the electric-conductor, and the electric-conductor indirectly couples the radiating element in a capacitively coupled manner.

Abstract: An electronic device comprises a first radiator coupled to a second radiator. One end of a second branch of the second radiator is connected between a head end and a tail end of a first branch of the second radiator. The other end of the second branch is connected between a head end and a tail end of a third branch of the second radiator. A projection of a reference face of the first branch on the first radiator is a first projection. The first projection partly overlaps the first radiator, or a distance between the first projection and the first radiator is within a range of 0 to 3 millimeters. A ratio of a first center distance between an end face of the third branch and the reference face, and a second center distance between the other end face of the third branch and the reference face is within a range of 0.5 to 2.
