摘要： A wireless power receiving system includes antenna arms and antenna grounds oriented in horizontal directions and an electrical connection oriented in vertical direction that has a low impedance at a pre-determined frequency of a transmitted wireless power wave. The electrical connection connects the antenna grounds perpendicular to the electrical connection. The wireless power receiving system can receive both the horizontal and vertical polarized E-fields of the transmitted wireless power wave emitting from a wireless power transmitter. In some embodiments, a battery with a vertical outer case forms the electrical connection, and both vertical and/or horizontal currents can be induced by the transmitted power wave polarized in any direction on the horizontal antenna grounds and/or the vertical outer case of the battery. In some embodiments, a metalized fixture or a metallic clamp forms the electrical connection.

摘要： Technologies are generally described to provide adaptable near field communication (NFC) in portable devices to enable a portable device to provide wireless power transfer (WPT) functionality and NFC functionality. According to some examples, a wireless power antenna installed on the portable device may be configured to function as a WPT antenna and as an NFC antenna. For example, the wireless power antenna may be a coil, which may be modified to adjust a quality factor (Q) by incorporation of a switchable resistor element. The modified coil may function as a wireless power receiver/transmitter with a high Q value when the resistor element is added and as an active NFC antenna with a low Q value when the resistor is not added. Additionally, the modified coil may further enable the portable device to function as a passive NFC antenna when the portable device is unpowered.
