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.
