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.
