Patent attributes
An antenna system and a mobile terminal are provided. The antenna system includes a front frame rib connecting a system ground with a first short-axis frame, a slit provided on a first long-axis frame, a radio frequency front end area provided in system ground, and first and second frame-joint points each connecting radio frequency front end area with a metal frame. The first and second frame-joint points are located between front frame rib and slit. The radio frequency front end area includes a feeding point, a matching circuit, an impedance tuning circuit and a switching circuit. The impedance tuning circuit and the switching circuit are adjusted to switch an operating state of antenna system in such a manner that the antenna system operates in different frequency bands. The antenna system includes one operating state in which the antenna system operates in a frequency band ranging from 1710 MHz to 2700 MHz.
