Security tag and process for making same
First Claim
1. A method of making a resonant tag comprising the steps of:
- forming a first adhesive layer in a first predetermined pattern on a surface of a first substrate;
laminating a first conductive foil to the surface of the first substrate to form a first conductive layer;
forming a first portion of the first conductive layer in a shape generally corresponding to the first predetermined pattern; and
removing a second portion of the first conductive layer not corresponding to the first portion to thereby establish a first conductive trace on the surface of the first substrate.

Abstract
A method of making a resonant frequency circuit is disclosed. The method includes the steps of: (1) forming a first adhesive layer in a first predetermined pattern on a surface of a first substrate; (2) laminating a first conductive foil to the surface of the first substrate to form a first conductive layer; (3) forming a first portion of the first conductive layer in a shape generally corresponding to the first predetermined pattern; and (4) removing a second portion of the first conductive layer not corresponding to the first portion to establish a first conductive trace on the first substrate. A third conductive trace is formed on a third substrate. The third conductive trace is secured to the first conductive trace with a dielectric layer therebetween to form the resonant frequency circuit.
