NFC ANTENNA MODULE AND NFC MODULE INCLUDING THE SAME

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.

主权项

1. A near field communication antenna (NFC) module comprising:
an NFC controller including an NFC transmitter, an NFC receiver and an NFC card; a matching circuit including a transmitter interface connected to the NFC transmitter, a receiver interface connected to the NFC receiver and a card interface connected to the NFC card; and an antenna module including a first terminal, a second terminal, an antenna connected to the first and second terminals, and a resonance unit, wherein the resonance unit is connected to the first and second terminals and includes a first passive device, a value of the first passive device being such that a resonance frequency between the first and second terminals is in a predetermined frequency range.
