Abstract: An antenna has an exciting element disposed above a ground plane of an electronic device. Power fed to the exciting element excites the ground plane to generate radiation. In this way, radiation capability of the ground plane is not affected by clearance between a display screen and the ground plane, and the antenna is applicable to an electronic device with limited antenna space. In addition, the ground plane serves as a radiation aperture of the electronic device.

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.
