Abstract
An illustrative example embodiment of a wireless power transfer device includes an inductor panel and a capacitor panel adjacent the inductor panel. The capacitor panel includes a first conductive plate adjacent one side of the inductor panel, a dielectric layer adjacent the first conductive plate, and a second conductive plate adjacent the dielectric layer on an opposite of the dielectric layer from the first conductive plate.
