Abstract
Disclosed is a common antenna for near field communication (NFC) and frequency modulation (FM). The common antenna comprises an antenna coil. The antenna feed line ends of the antenna coil are connected to an NFC matching circuit and an FM matching circuit, respectively. According to the disclosure, the antenna coil is connected to the NFC matching circuit and the FM matching circuit, respectively, so as to realize that the antenna is shared by the NFC and the FM, thereby reducing the costs, saving the space, and improving the product competitiveness.
