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： 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： 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.
