Summary:Disclosed is a near field communication (NFC) and frequency modulation (FM) antenna system which is applied to a portable electronic apparatus. The system comprises an antenna, an NFC chip, an FM chip, a master control chip, a common coupling module electrically connected with the antenna, a gating module electrically connected with the common coupling module and the master control chip, an NFC coupling module electrically connected between the gating module and the NFC chip, and an FM coupling module electrically connected between the gating module and the FM chip. The common coupling module is used for coupling the antenna to multiple frequency bands for sharing, the master control chip is used for sending a control signal to the gating module and controlling the gating module to conduct the antenna to the NFC coupling module and the NFC chip or conduct the antenna to the FM coupling module and the FM chip, when the antenna is conducted and connected to the NFC chip, the NFC coupling module is used for tuni
