  • Patent number: 10522896
    Abstract: A directional coupler includes an electrically conductive main line coupled at least partially in and/or on a dielectric layer and having input and output ports. An electrically conductive coupled line separated from the main line includes a coupled port and is at least partially formed in and/or on the dielectric layer. An electrically conductive ground layer couples with the dielectric layer and is electrically isolated from the main and coupled lines. One or more tuning elements, formed of electrically conductive elements arranged in a pattern (but electrically isolated from the main and coupled lines and ground layer) and/or formed using an electrically conductive layer (the electrically conductive layer electrically isolated from the main and coupled lines and ground layer and with or without a pattern of openings therein) are at least partially encapsulated in the dielectric layer and increase a coupling coefficient and/or directivity of the directional coupler.

  • Publication number: 20190296587
    Abstract: A wireless power transmission (WPT) system. Implementations may include a power source coupled with a first wireless power transmission (WPT) system and a load coupled with a second WPT system including a sense circuit. The second WPT system, using the sense circuit, may be configured to dynamically tune a resonance of the second WPT system with the first WPT system to a desired resonance frequency value to allow transfer of a desired voltage or a desired power to the load. The desired resonance frequency value may be less than a maximum possible resonance frequency value. The first WPT system may be capable of transmitting more voltage or more power than the second WPT system or the load can receive without inducing damage to the second WPT system or the load.

  • Publication number: 20190089210
    Abstract: A tunable resonant inductive coil system includes an electrical circuit having an alternating current (AC) voltage source, a barium strontium titanate (BST) variable capacitor coupled in series with a first terminal of the AC voltage source, a coil coupled in series with the BST variable capacitor, and a return line coupling the coil with a second terminal of the AC voltage source and/or a ground. The electrical circuit forms an LC circuit (resonant circuit). The electrical circuit adjusts between two configurations. In the first configuration the resonant circuit has a first resonant frequency configured for wireless power transfer and in the second configuration it has a second resonant frequency configured for near field communication (NFC). An entire length of the coil is used for both resonant frequencies. Adjusting between the first and second configurations includes varying a capacitance of the BST variable capacitor in response to receiving a control signal.
