    摘要： Techniques are disclosed involving reconfigurable coils. Such coils may be used in applications, including (but not limited to) wireless charging and near field communications (NFC). For instance, a reconfigurable coil may include a first conductive portion and a second conductive portion. Two or more configurations may be established. These configurations may correspond to particular current paths. For example, in a circular configuration, a path is provided having the same rotational sense in both first and second conductive portions. However, in a figure eight configuration, a path is provided having a first rotational sense in the first conductive portion and a second rotational sense in the second conductive portion. A switch coupled between these portions may set the coil's configuration. Configurations may be selected based on one or more operating conditions involving the coil.

    摘要： Described herein are techniques related to near field coupling and wireless power transfers. A portable device may include a coil antenna that includes an upper loop and a lower loop to form a figure-eight arrangement. The figure-eight coil antenna arrangement is wrapped against top and bottom surfaces of a component to establish near field coupling through front side, top side, bottom side, or corner side of the portable device. Further, a flux guide may be placed between the coil antenna and the component to facilitate magnetic flux at the upper loop and the lower loop to induce current of the same phase during receive mode. During transmit mode, the flux guide facilitates the magnetic flux at the upper loop and the lower loop to generate magnetic fields of the same direction.

    摘要： Described herein are techniques related to near field coupling and wireless power transfers. A device may include a cascaded coil antenna to include a first coil antenna that is connected in series with a second coil antenna. The first and second coil antennas are independent antennas prior to cascading and are located in different surfaces of the device to establish near field coupling through front side, top side, bottom side, or corner side of the portable device. Furthermore, a flux guide may be placed in the cascaded coil antenna to facilitate magnetic flux at the first coil antenna and the second coil antenna to induce current of the same phase during receive mode. During transmit mode, the flux guide facilitates the magnetic flux at the first coil antenna and the second coil antenna to generate magnetic fields of the same direction.

    摘要： Embodiments of a planar asymmetric antenna structure with shifted feed position for multi-protocol operations are disclosed The antenna structure includes two elliptically tapering right and left arms, each with a different radius, and an off-center feed point positioned between the right and left arms. One arm has a smaller elliptical tapering than the other arm and the feed point is positioned closer to one arm than the other arm. A method of synthesizing a multiprotocol antenna pattern is also disclosed. The method includes providing substantially equally surface currents on both arms of an antenna structure to generate a near-horizontal pattern in far-field at a lower frequency band, providing greater surface currents on the right arm to generate a far-field pattern with a large horizontal component at a higher frequency band, and providing greater surface currents on the left arm to generate an asymmetric far-field pattern at a middle frequency band.

    摘要： Embodiments of a system and method of determining total isotropic sensitivity (TIS) of a wireless broadband client device are described herein. A received signal strength indicator (RSSI) reported at an embedded radio module of the device is logged for each of a plurality of antenna polarizations and for each of a plurality of platform orientations. A single point measurement of module sensitivity is performed at a reference orientation and polarization the transmit antenna. The TIS is calculated as a correction to the single point measurement of module sensitivity. A correction factor to correct the TIS may be based on the difference between an average of the logged RSSIs and an RSSI at the reference orientation and polarization of the transmit antenna.
