    摘要: This disclosure provides systems, methods and apparatus for forward link communication in wireless power systems. One aspect of the disclosure provides a wireless charging device for providing wireless power to a receiving device. The wireless charging device includes a primary transmit antenna configured to generate a wireless power field. The device further includes a parasitic antenna configured to selectively adjust a coupling between the primary transmit antenna and the receiving device. The device further includes a controller configured to control the selective adjustment of the parasitic antenna so as to communicate with the receiving device.

    摘要: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may use transmissions causing power density exposure (PDE) to nearby users. To reduce the PDE of an antenna module (e.g., below a maximum PDE threshold), the UE may implement a shielding strip around the antenna module. For example, the antenna module may include a substrate having a first surface and a set of antenna elements on the first surface. The shielding strip may enclose the set of antenna elements of the antenna module and extend away from the first surface above the antenna elements. The shielding strip may reduce PDE outside a field of view of the antenna module. Additionally, in some cases, the placement of the antenna module in the UE and the materials used for constructing the UE may further reduce PDE.

    摘要: A method of sending and receiving dual-polarization, millimeter-wave signals to and from a mobile device having a top surface, a bottom surface, and an edge surface, includes: radiating energy, in a millimeter-wave frequency band, from a first radiator outwardly from the edge surface with a first polarization; receiving, via the first radiator, energy in the millimeter-wave frequency band with the first polarization; radiating energy, in the millimeter-wave frequency band, from a second radiator outwardly from the edge surface with a second polarization substantially perpendicular to the first polarization, the second radiator being disposed between the first radiator and the top surface or the bottom surface, or a combination thereof; and receiving, via the second radiator, energy in the millimeter-wave frequency band with the second polarization.

    摘要: A multi-band antenna having an aperture tuner is disclosed. The multi-band antenna may simultaneously transmit a first radio frequency (RF) signal and a second RF signal. The aperture tuner may modify a resonant frequency associated with one or more antenna elements of the multiband antenna in accordance with the first RF signal or the second RF signal. One or more of the antenna elements of the multi-band antenna may be disposed above and/or substantially parallel to other antenna elements. In some exemplary embodiments, an air gap may be formed between one or more antenna elements.

    摘要: Methods and devices of various embodiments enable determining a location of a remote object using radio frequency signal transmitted from a transmitter on a frame and received at four receivers located at separate locations on the frame. First, second, third, and fourth reflected signals from a remote object may be received at first, second, third, and fourth receivers respectively. Times at which the first, second, third, and fourth reflected signals are received respectively by the first, second, third, and fourth receivers may be determined. The remote object's location may be determined based on the determined times at which the first, second, third, and fourth reflected signals were received respectively and the locations on the frame of the first, second, third, and fourth receivers.

    摘要: A multi-band antenna having a tuned antenna element is disclosed. The multi-band antenna may simultaneously transmit a first radio frequency (RF) and a second RF signal. The antenna may include a driven antenna element to radiate the first RF signal and a parasitic element to radiate the second RF signal. The parasitic element may be coupled to a ground plane through a tuning circuit. The tuning circuit may modify a resonant wavelength of the parasitic element according to the second RF signal.
