Abstract
A mobile wireless communications device may include a wireless transceiver, a processor coupled to the wireless transceiver, and a near-field communication (NFC) device coupled to the processor. The NFC device may include an NFC controller, an NFC transceiver coupled to the NFC controller, and spaced apart NFC antennas. The NFC device also includes a scanning switch coupled between the spaced apart NFC antennas and the NFC transceiver. The NFC controller may be configured to operate the scanning switch to successively couple each NFC antenna to the NFC transceiver, while attempting to establish NFC communication with an adjacent NFC device. The NFC device may also be configured to lock coupling to a corresponding NFC antenna upon establishing NFC communication with the adjacent NFC device.
