A coil-in-coil structure () is formed within two devices (). The coil-in-coil structure () enables both wireless charging and secure pairing between the two devices (). The coil-in-coil structure () permits expanded wireless functionality using a single transmit coil () at a host radio device () and a receive coil () at an accessory device (). A plurality of different accessory devices () can be interchangeably accommodated via a single host port () of the radio device ().

Apparatus, method and system for providing expanded functionality to communication devices using wireless charging coil-in-coil

An antenna arrangement () and communication device () using the antenna arrangement connect a plurality of transceivers () to a plurality of antenna elements () and switches connections between the transceivers and the antenna elements depending on which transceiver has primary transmit control. The antenna elements include a transmit antenna element () and a monitoring antenna element (). The transceiver having primary transmit control is connected to the transmit antenna element and the transceiver not having primary transmit control is connected to the monitoring antenna element.
