摘要：
A matching circuit of a near field communication (NFC) device includes a resonance unit connected between a first terminal and a second terminal of an antenna. The antenna is responsive to an electromagnetic wave. The resonance unit includes a first capacitor connected between the first terminal and the second terminal of the antenna. A matching unit is configured to perform impedance matching between the antenna and an NFC chip. The matching unit is connected between the first terminal and the second terminal of the antenna.
