The present invention belongs to the field of wireless communication, and specifically relates to a passive NFC communication interface having an independent energy receiving antenna. The passive NFC communication interface comprises an NFC passive communication circuit for passive communication and a radio frequency energy receiving circuit for NFC radio frequency energy receiving. The NFC passive receiving circuit comprises an NFC communication antenna, a communication antenna matching circuit and a NFC transceiver, wherein the NFC communication antenna is connected to the NFC transceiver via the communication antenna matching circuit. According to the present invention, energy receiving power of an NFC passive communication interface is greatly improved, and a large amount of electricity is supplied to a device with the passive NFC communication interface. According to the additional electricity, the device is permitted to provide more functions, performance is higher and user experience is better. The application range of an NFC passive communication interface is greatly extended by the present invention at present and in the next few years.
