Abstract

A tag having a substrate having a surface with a preformed first patterned adhesive disposed over the surface thereof and a first layer of electrically conductive material having a shape corresponding to a desired final pattern for a first electrically conductive trace secured to the surface of the substrate. The preformed first patterned adhesive corresponds to the desired final pattern. A second patterned adhesive is disposed over a portion of a surface area of the tag. An electrically conductive trace is disposed over the second patterned adhesive to adhere the second electrically conductive trace thereto. An electrical connection is provided for electrically coupling portions of the first and second electrically conductive traces to form a tag circuit. The tag circuit can be an LC resonant circuit. The preformed first patterned adhesive can be a flexographic printed layer.
