Abstract:
This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect the disclosure provides an apparatus for wirelessly communicating power. The apparatus includes a first conductive structure, with a length greater than a width, configured to wirelessly receive power via a magnetic field. The first conductive structure includes two substantially co-planar loops. The first conductive structure has a first edge and a second edge each intersecting a geometric line along the length of the first conductive structure. The apparatus further includes a second conductive structure, with a length greater than width, positioned between the first conductive structure and a magnetic material and configured to wirelessly receive power via the magnetic field. The length of the second conductive structure is substantially equal to at least a distance along the geometric line between the first edge and the second edge of the first conductive structure.
