Abstract
A wireless power system, preferably including a set of one or more substrates and a wireless power receiver, wherein the wireless power receiver preferably includes one or more radio frequency (RF) impedance sheets. A method of operation for a wireless power system, preferably including receiving power wirelessly and/or delivering power to one or more electrical loads, and optionally include deploying the system and/or stowing the system S240.
Claims20
A wireless power system comprising:
- a substrate defining a first broad face and a second broad face, wherein:
- the substrate is a dielectric;
- the second broad face is substantially parallel to the first broad face;
- the substrate defines a first plane substantially parallel to the first broad face;
- and
- the substrate defines a plurality of apertures, wherein each aperture of the plurality intersects the first broad face, the second broad face, and the first plane;
- a first set of electrical conductors, wherein each electrical conductor of the first set:
- is electrically connected to all other electrical conductors of the first set;
- is arranged on a second plane, the second plane substantially parallel to the first plane;
- and
- does not intersect the plurality of apertures;
- a second set of electrical conductors, wherein each electrical conductor of the second set:
- is electrically connected to all other electrical conductors of the second set;
- and
- does not intersect the plurality of apertures;
- a plurality of rectifiers, wherein, for each rectifier of the plurality:
- the rectifier comprises a respective first DC output terminal and a respective second DC output terminal;
- the respective first DC output terminal is electrically connected to the first set of electrical conductors;
- and
- the respective second DC output terminal is electrically connected to the second set of electrical conductors;
- and
- a plurality of antenna elements, wherein each antenna element of the plurality of antenna elements:
- is electrically connected to none of the other antenna elements of the plurality of antenna elements;
- is electrically connected to a respective rectifier of the plurality of rectifiers;
- is electromagnetically coupled, via a set of radio frequency (RF) evanescent modes through at least one of the substrate or the plurality of apertures, to the first set of electrical conductors;
- is arranged on the first plane;
- and
- does not intersect the plurality of apertures.
