NFC antenna using dual resonance
First Claim
1. An NFC antenna using a dual resonance, comprising:
- an NFC antenna unit embedded in a portable wireless terminal, transmitting a signal transmitted by an external reader by communicating with the reader to an NFC chip and transmitting a signal provided by an NFC chip to the reader; and
a relay unit embedded in the portable wireless terminal, relaying a signal transmitted by the reader to the NFC antenna and relaying a signal transmitted through the NFC antenna to the reader;
wherein the NFC antenna unit and the relay unit are mounted at an inside of a battery pack that comprises a battery and a PCM (Printed Circuit Module) for protecting the battery, the PCM positioned by the battery,wherein the NFC antenna unit is formed at the PCM, andwherein the relay unit is positioned on the battery and the PCM.

Abstract
The present invention is disclosed to provide an NFC antenna using dual resonance, wherein a closed circuit is formed by a capacitor and a loop antenna, and a relay unit is attached to a portable wireless terminal that forms a resonance to a predetermined frequency signal mutually transmitted between a portable wireless terminal reader and an NFC chip, and in the course of communicating between the NFC chip and the reader, the relay unit relays a signal transmitted by the reader to an NFC antenna unit, and the NFC chip relays a signal transmitted through the NFC antenna unit to the reader to thereby increase a recognition distance capable of obtaining predetermined information.
