Abstract: A Near field communication (NFC) antenna and circuit modules are provided for communication terminal devices with metal frame, which aims at simplifying the implementation of the NFC antenna, and especially facilitating the application of the NFC for the devices with rear metal housing. The rear metal housing of a terminal device may be divided into three sections by the gap, the first section is metal frame, the second section is metal back shell. The metal frame as the main NFC antenna radiator, and also can be used as other microwave frequency antenna radiator. The rear metal shell connected to the motherboard ground. The NFC circuit module can transmit the NFC signal to the metal frame through different feeding methods to realize the radiation function of the NFC antenna.

Abstract: The present invention discloses an NFC antenna apparatus, which includes a metal cover, and an antenna module having a conductive coil. The metal cover is equipped with at least two openings and at least one slot. The slot is used to connect with different openings. The conductive coil intersects with at least one slot. The present invention also discloses a mobile terminal. This invention can reduce the degree of damage to the metal cover through changing slotting method of NFC antenna, increase the strength of the structure of the NFC antenna apparatus, and thus enhance the strength of the structure of the mobile terminal.
