Disclosed is a miniaturized NFC antenna, which has a unidirectional transmission function and can prolong communication distance and improve communication quality. The antenna comprises an organic matrix and a thin-type magnetic medium, wherein the organic matrix comprises a first organic board and a second organic board. The thin-type magnetic medium is clamped between a lower surface of the first organic board and an upper surface of the second organic board. The organic matrix and the thin-type magnetic medium are both provided with a first metallized via hole, a second metallized via hole and a third metallized via hole, so that a first antenna wiring arranged on an upper surface of the first organic board, a third antenna wiring arranged on the lower surface thereof, and a fourth antenna wiring arranged on the upper surface of the second organic board can be electrically connected through these metallized via holes. In addition, the first antenna wiring is connected to a first transmitting end, and the second antenna wiring is connected to a second transmitting end. Also provided is a mobile terminal. The antenna can be utilized for satisfying the design requirements of portability, light weight and thinness.
