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 of a mobile terminal is provided. At least two slots are disposed in a metal bezel of the mobile terminal, and the two slots divide the metal bezel into a first metal section, a second metal section, and a third metal section. A radiating element of the antenna includes the second metal section located between the two slots, a first conductor, and a second conductor. The first conductor and the second conductor are separately connected to the second metal section. A feed point is connected to the first conductor by using a matching network. A ground point is connected to the second conductor to form a loop antenna. An electrical length path of current from the feed point to the second metal section is not equal to an electrical length path of current from the ground point to the second metal section.
