Wireless power receivers include a first inductive element featuring 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 first capacitive element at a third terminal and to the second terminal, a rectifier connected to the second terminal and third terminal such that an oscillating magnetic field will induce a current in the first inductive element, resulting in a voltage across the input of the rectifier, a communications modulation circuit, and a layer of magnetic material centered over the planar coil in a second plane parallel to the first plane.
