An embodiment of the invention discloses a miniature 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 the lower surface of the first organic board and the upper surface of the second organic board. The organic matrix and the thin type magnetic medium are respectively provided with a first metalized via hole, a second metalized via hole and a third metalized via hole, so that a first antenna wiring arranged on the upper surface of the first organic board, a third antenna wiring which is arranged on the lower surface of the first organic board, and a fourth antenna wiring which is arranged on the upper surface of the second organic board can be electrically connected through the metalized via holes. Furthermore, the first antenna wiring is connected with a first transmitting end, and the second antenna wiring is connected with a second transmitting end. The embodiment of the invention further provides a mobile terminal. The miniature NFC antenna can be utilized for satisfying designing requirement of high portability, small weight and small thickness.
