PORTABLE DEVICE USING A COMMON ANTENNA FOR BOTH NEAR FIELD COMMUNICATION AND WIRELESS CHARGING
First Claim
1. A portable device using a common antenna for both near field communication (NFC) and wireless charging, the portable device comprising:
- a common antenna part transmitting and receiving near field communication and wireless charging signals;
an NFC signal judgment module connected to the common antenna part and sensing a signal applied from the common antenna part or a Tx signal generated from an NFC performing part to thereby judge whether or not the signal applied from the common antenna part or the Tx signal is a near field communication signal;
the NFC performing part connected to the NFC signal judgment module and performing near field communication according to a control signal transferred from the NFC signal judgment module; and
a battery part connected to the NFC signal judgment module and being wirelessly charged according to the control signal transferred from the NFC signal judgment module.
