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: An antenna is provided, which includes: a main stub, a first parasitic stub, and a second parasitic stub. The first parasitic stub and the second parasitic stub are respectively arranged on two sides of the main stub. The first parasitic stub and the second parasitic stub are configured to excite resonances to improve main resonance efficiency or expand bandwidth. A frequency of the resonance excited by the first parasitic stub is greater than a frequency of a resonance excited by the main stub. A frequency of the resonance excited by the second parasitic stub is less than the frequency of the resonance excited by the main stub.

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, thereby effectively increasing a height of the radiating element of the antenna relative to a circuit board with the antenna not affecting an appearance of the mobile terminal. Compared with a conventional support solution, this manner can increase a height of about 0.2 mm to 0.6 mm. This reduces an impact caused by a metal component on the circuit board on antenna radiation, and further increases a bandwidth and efficiency of the antenna so that the antenna can cover a frequency band used in a handheld communications system.
