Abstract: The present invention provides an antenna system applied to a mobile terminal. The mobile terminal includes a metal bezel, a plastic back shell and a main board. The antenna system includes a metal trace. The metal trace includes a feed section, a radiating section, a first loop unit and a second loop unit. The main board is provided with one feed point connected to both the feed section and the metal bezel, two ground points respectively connected to an end, away from the feed section, of the first loop unit and an end, away from the feed section, of the second loop unit, and a tuning switch connected to the metal bezel.
