PORTABLE DEVICE USING A COMMON ANTENNA FOR BOTH NEAR FIELD COMMUNICATION AND WIRELESS CHARGING

摘要

The present invention relates to a portable device using a common antenna for both near field communication (NFC) and wireless charging, and more particularly to a portable device using a common antenna for both near field communication and wireless charging which includes a common antenna part (10) for transmitting and receiving NFC signals and wireless charging signals, an NFC signal judgment module (100) connected to the common antenna part (10) for judging whether a received signal is an NFC signal or not by detecting a signal applied from the common antenna part (10) or a Tx signal generated from an NFC performing part (200), the NFC performing part (200) connected to the NFC signal judgment module (100) for performing near field communication according to a control signal transferred from the NFC signal judgment module (100), and a battery part (300) connected to the NFC signal judgment module (100) for obtaining wireless charging according to a control signal transferred from the NFC signal judgment module (100).
