Claim 8:
9. A wireless power transmitter, comprising:
a first inductive element comprising a planar coil occupying a first plane and having first and second terminals;
a first capacitive element connected to the first terminal;
a second capacitive element connected to the second terminal;
a third capacitive element connected to the first and second capacitive elements to form a first conductive path between the first and third capacitive elements, and to form a second conductive path between the second and third capacitive elements;
an inverter configured to provide an oscillating voltage signal to the first inductive element, through the first capacitive element, such that the first inductive element generates an oscillating magnetic field for transmitting power in response to the oscillating voltage signal; and
a second inductive element connected between a first output of the inverter and the first conductive path;
a third inductive element connected between a second output of the inverter and the second conductive path; and
a layer of magnetic material, disposed over the planar coil in a second plane parallel to the first plane.
