The invention discloses an antenna comprising a ground, a metal frame and metal wiring adjusting a resonant frequency of the antenna. The metal frame has the shape of an enclosed frame without gaps. The ground and the metal wiring are arranged in the metal frame. The ground is electrically connected to the metal frame, and a wiring space is provided between the ground and an inner side surface of the metal frame. The metal wiring is arranged in the wiring space. The metal wiring includes a tuning arm and a feed arm. The tuning arm is connected to the metal frame. The feed arm is connected to the metal frame and the ground. The metal frame and the ground are electrically connected. The metal frame acts as a primary radiation body of the antenna. The metal wiring is adopted to adjust a resonant frequency of the antenna so as to cover a corresponding frequency band. By utilizing this mode of radiation, the metal frame can be enclosed without gaps so as to guarantee structural strength and a pleasing outward appearance of a mobile terminal. The invention also discloses a mobile terminal with the antenna. |
