A mobile wireless communications device includes a near-field communications (NFC) transceiver, NFC antennas and an NFC control circuit. The NFC transceiver generates a received signal strength based on a received signal from an adjacent NFC device. The NFC control circuit includes an antenna switch circuit coupled between the NFC transceiver and the NFC antennas. A capacitance sensing circuit is coupled to the NFC antennas to determine capacitance values thereof. A processor operates the antenna switch circuit based upon the received signal strength and the capacitance values.

A mobile wireless communications device includes a wireless local area network (WLAN) radio configured to generate a WLAN transmit signal, and a Bluetooth radio configured to generate a Bluetooth transmit signal. A circulator is coupled downstream of an antenna. A transmit path couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of transmitting simultaneously. In addition, a receive path also couples the WLAN radio and the Bluetooth radio to the circulator such that the WLAN radio and the Bluetooth radio are capable of receiving simultaneously.
