The invention provides an antenna system and a mobile terminal, wherein a resonance arm is separated from a metal shell of the mobile terminal, and the antenna system comprises the resonance arm, andtuning circuits and feed source circuits arranged between the resonance arm and the grounding end. The resonance arm is formed by arranging a slit on the metal shell, the feed source circuits are arranged on resonance arm, the tuning circuits are arranged at the tail end of the resonance arm. The switching of the radiation modes is realized at the feed source end of the resonance arm and the tailend of the resonance arm through a switch combination of the tuning circuits, so that medium-high frequency band bandwidth coverage in small clearance environment can be realized by using a single antenna, and the bandwidth requirements of the antenna efficiency and the frequency band in the mobile terminal are met.
