Abstract

The embodiment of the present invention discloses an NFC antenna device and a mobile terminal. The NFC antenna device provided by the embodiment of the present invention comprises an NFC antenna unit and an SIM card. The SIM card comprises an NFC antenna and an NFC unit. The above NFC antenna unit is used for carrying out NFC signal interaction with external NFC equipment and coupling the first NFC signal sent by the external NFC equipment to the NFC antenna. The NFC unit is used for receiving the first NFC signal from the above NFC antenna and processing the first NFC signal to realize an NFC function. The device can send the NFC signal received by the NFC antenna in the terminal to the SIM card, the SIM card carries out corresponding NFC processing, the technical problem that the mobile terminal with a metal back shell shields the NFC antenna in the SIM card is solved, and thus the mobile terminal can normally use the NFC function of the SIM card.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an NFC antenna device and a mobile terminal. Background technique [0002] With the rapid development of terminal devices, mobile payment has become one of the most popular applications in the radio frequency identification industry, such as NFC (Near Field Communication, near field communication) payment. NFC is a short-distance high-frequency wireless communication technology that works in the 13.56MHz frequency range. With the popularization of mobile consumer electronics products such as smart phones, NFC systems with low energy consumption and fast data transmission speed are used in mobile payment and electronic identity authentication. , Electronic tickets and other fields have been widely used. [0003] At present, the development trend of mobile phones is towards thinner and multi-functional development. As the thickness of the mobile phone is getting thinner, i...
