Patent
Wireless charging systems and methods
TL;DR: In this paper, an embodiment of a system for wirelessly charging a wrist-worn device may include a radio frequency charging energy generating element, and an antenna configured to radiate the RF charging energy, the antenna comprising a first coil and a second coil, each comprising a plurality of windings, the windings of the first coil being wound in a direction opposite the direction of the second coil.
Patent
Apparatus for wireless device charging using radio frequency (rf) energy and device to be wirelessly charged
TL;DR: In this paper, an apparatus for wireless charging using radio frequency (RF) energy includes a first charger portion having first and second charging areas, each having at least one coil for wirelessly charging a charge-receiving device placed in proximity thereto.
Patent
Adaptable antenna system
TL;DR: In this paper, small, narrow-band and frequency adaptable antennas have been used to provide coverage to a wide range of wireless modes and frequency bands on a host wireless device.
Patent
Multiband antenna for a mobile device
TL;DR: In this article, a multiband antenna for a mobile device is described, which includes a ground plane, ground plane extension, and a plurality of antenna arms, where the ground plane has a length proportional to approximately a quarter wavelength of a frequency in the multiple frequency bands.
Patent
Systems and methods for forward link communication in wireless power systems
TL;DR: In this article, the authors provide a wireless charging device for providing wireless power to a receiving device, which includes a primary transmit antenna configured to generate a wireless power field, and a parasitic antenna that adjusts a coupling between the primary transmitter and the receiving device.
