A method of making a resonant frequency tag which resonates at a
predetermined frequency. The method involves providing a first conductive
pattern having an inductive element and a first land and a second
conductive pattern having a second land and a third land which are joined
together by a link. The second conductive pattern is overlaid the first
conductive pattern such that the second land is positioned over the first
land. The third land is in electrical communication with the inductive
element of the first conductive pattern. The formed resonant frequency
tag is energized to determine if the tag resonates at the predetermined
frequency. If the tag resonates properly, the third land is electrically
coupled to the inductive element. If it does not, the second conductive
pattern is adjusted so that overlapping portions of the first and second
lands are changed, altering the capacitance to adjust the resonant tag
frequency.
