ABSTRACT:
A method of making a resonant frequency tag having a predetermined frequency comprises forming a first conductive pattern comprising an inductive element and a first land having a first end connected to an inductive element end, and a second end spaced a predetermined distance from the first end; separately forming a second conductive pattern comprising a second land having a predetermined width and a link element; placing the second conductive pattern proximate the first conductive pattern at a first location wherein the second land overlies a portion of the first land with a dielectric therebetween establishing capacitive element plates having a first capacitance along with the inductive element forming a resonant circuit; measuring the resonant circuit frequency and comparing the measured and predetermined frequencies moving the second land along of the first land length to match the resonant frequency; and securing the second conductive pattern to the first conductive pattern.
