description The utility model provides an NFC antenna module, an NFC initiator and an NFC target device, suitable for the field of data communication. The NFC antenna module comprises at least one NFC antenna coil, a chip and a metal casing of a determined shape, wherein the metal casing, the chip and the NFC antenna coil are connected in series to form a loop, and the NFC antenna coil and the chip are arranged in the metal casing. The metal casing which serves as part of the NFC antenna coil is connected in parallel with the chip, so that the problem of magnetic field coupling of the metal casing is solved, and an NFC reader consisting of the NFC antenna module can carry out communication by penetrating through the metal casing; and further, the antenna space is saved, inductance required by 13.56MHz resonance in the chip can be generated, and the NFC antenna coil can be placed in the metal casing.
