Abstract
A mobile wireless communications device may include a housing, a wireless transceiver carried by the housing, a processor carried by the housing and coupled to the wireless transceiver, and an NFC IC carried by the housing and coupled to the processor. The mobile wireless communications device may also include an NFC antenna carried by the housing, and a coupling circuit between the NFC IC and the NFC antenna. The coupling circuit may include a capacitive network including capacitors coupled in series with each other and in parallel with the NFC antenna, a transmit branch coupled between the NFC IC and a first node between a first pair of capacitors, and a receive branch coupled between the NFC IC and the first node between the first pair of capacitors.
