摘要： A resonance frequency of a near field communication (NFC) antenna module may be set to be equal to a first frequency by a resonance unit included in the NFC antenna module. The NFC module may include a matching circuit connected to the NFC antenna module. The matching circuit may include terminals exposed to the outside such that the antenna module is detachable from the matching circuit.
