Abstract
In one aspect, the present invention provides an integrated inductor and capacitor 20 which can be used as the inductive portion of a resonant circuit and the energy accumulator for a identification system transponder. In a first embodiment, the integrated inductor and capacitor component 20 may include first and second strips of electrically conductive material 22 and 26, for example aluminum. The first and second strips 22 and 26 are wound in a coil 20 to form a plurality of windings. Each winding is electrically insulated from adjacent ones of the windings by insulators 24 and 28. The component can be bonded to a transponder chip.
