    摘要: A balanced antenna is integrated into a wireless mobile device, such as a laptop computer, for improved antenna reception. The antenna is connected to a radio frequency (RF) interconnection cable. A balun is disposed between the antenna and the cable. By using a balanced antenna, the fraction of the noise produced by the motherboard and display of the wireless mobile device that is captured by the antenna is significantly reduced compared to that captured by an unbalanced antenna, and thus not captured by the antenna.

    摘要: 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.
