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

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.
