HONEYCOMB MULTI-DD COIL DESIGN FOR WIRELESS POWER TRANSFER SYSTEMS

A coil, comprising: a wire wound to form a plurality of double-D (DD) sub-coils, each said DD sub-coil having a plurality of sides defining one of a plurality of hexagonal shaped segments arranged to define a honeycomb structure; wherein a magnetic field is created when current passes through the plurality of DD sub-coils, the plurality of DD sub-coils being configured so that when activated the current flows in a same first direction through adjacent sides of first and second ones of the plurality of DD sub-coils, flows in a same second direction through adjacent sides of first and third ones of the plurality of DD sub-coils, and flows in a same third direction through adjacent sides of the second and third ones of the plurality of coils.
