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.
