A transceiver for near field communication (NFC) according to the present invention comprises: a resonant cavity, a first capacitor, a second capacitor, and a filter. The resonant cavity is connected between a first node and a second node, has a resonant frequency, and transmits and receives a signal by using an electromagnetic wave. The first capacitor is connected between the first node and a third node. The second capacitor is connected between the second node and a fourth node. The filter is connected to among a first transmission terminal, a second transmission terminal, the third node, and the fourth node in an asymmetrical structure, and provides a different frequency response to the first transmission terminal and the second first transmission terminal. |
