Abstract
An identification device includes a first metal layer patterned into a planar coil winding and a second metal layer electrically connected to the first metal layer. The first metal layer is operable to provide a circuit inductance. The second metal layer is patterned to provide one or more overlapping areas with the first metal layer. The second metal layer is operable to provide a circuit capacitance. The identification device includes a dielectric layer separating the first metal layer and the second metal layer.
