    Abstract: Technology for impedance matching with a re-configurable coil arrangement of multiple transmitter coils of an electronic device is described. One electronic device includes a wireless transmitter coupled to a power supply and an impedance matching circuit coupled to output terminals of the wireless transmitter. First switching circuitry of the impedance matching circuit, in response to a first control signal, is to switch either a first transmitter coil or a first conductive path in series between the output terminals. Second switching circuitry of the impedance matching circuit, in response to a second control signal, is to switch either a second transmitter coil or a second conductive path in series between the output terminals. The first transmitter and first conductive path have the same impedance and the second transmitter and the second conductive path have the same impedance.

    Abstract: Apparatus, system and method to provide switchable coils in a computing device, comprising: a plurality of electrically conductive coils to transfer electromagnetic energy; a sensor coupled to a processor, to select a coil from among the plurality of electrically conductive coils; a switch to energize the selected coil; and a switch controller coupled to the switch and to the processor. In some embodiments, the plurality of coils may comprise an inductive charging interface. Some embodiments may further include a communication interface between the processor to the plurality of electrically conductive coils, the plurality of coils comprising an interface for near-field communications (NFC). The antenna coils may be arranged to provide improved NFC coverage when the computing device is in a respective predetermined physical configuration. Sensors may be used to detect the configuration and switch NFC communications to use a preferred antenna coil for the detected configuration.
