Abstract
This disclosure provides systems, methods and apparatus for wireless power transfer. In one aspect, an apparatus is provided that includes a first conductive structure configured to wirelessly receive power via a magnetic field generated by a transmitter conductive structure having a length greater than a width. The first conductive structure has a length greater than a width and includes co-planar loops enclosing first and second areas. The first conductive structure has first and second edges each intersecting a first geometric line running along the length of the first conductive structure. The apparatus includes a second conductive structure configured to wirelessly receive power via the magnetic field. The second conductive has a length greater than a width. The first geometric line runs along the length of the second conductive structure. The first geometric line is substantially perpendicular to a second geometric line running along the length of the transmitter conductive structure.
