Abstract
A communication apparatus (10) has an antenna (12) suitable for transmitting and receiving signals in a near-field communication (NFC) frequency band. A resonant network is connected to the antenna (12), which is configured to adjust a self resonant frequency of the antenna (12) such that a signal in an FM frequency band may be transmitted or received by the antenna (12). An integrated circuit may be provided with the communication apparatus (10).
