First Claim
Patent Images
1. A method of forming a wireless component, comprising:
- forming a driving coil to receive a driven current generating a magnetic field;
forming an outer turn of a parasitic coil, wherein the outer turn is adjacent to the driving coil; and
forming an inner turn of the parasitic coil, wherein an inductive coupling between the driving coil and the parasitic coil generates a redistribution of a portion of the magnetic field at the inner turn.

Abstract
Techniques of magnetic field distribution are described herein. The techniques may include forming a wireless charging component including a driving coil to receive a driven current generating a magnetic field. An outer turn of a parasitic coil may be formed, wherein the outer turn is adjacent to the driving coil. An inner turn of the parasitic coil may be formed, wherein an inductive coupling between the driving coil and the parasitic coil generates a redistribution of a portion of the magnetic field at the inner turn.

23. A wireless transmitter, comprising:
-
a driving coil to receive a driven current generating a magnetic field; an outer turn of a parasitic coil disposed adjacent to the driving coil, and wherein an inductive coupling between the driving coil and the outer turn generates; a current at the outer turn propagating in a direction opposite to a direction of the current in the driving coil; and a reduction of the magnetic field at the driving coil; and an inner turn of the parasitic coil to receive the current from the outer turn, wherein the inner turn is disposed to propagate the current propagates in a same direction as the driven current to generate a magnetic field that is smaller than the magnetic field of the driving coil. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31)
