Radio frequency identification tags for use on metal or other conductive objects

Abstract

ID tags Radio Frequency FOR USE IN METAL OBJECTS OR OTHER OBJECTS DRIVERS. This is ID tags Radio Frequency ( "RFID") that are useful in metal surfaces or other conductive surfaces and methods for fabricating the same. In one embodiment, the radio frequency identification tag includes: a substrate including a first major surface and a second opposite major surface at the first main surface, a radio frequency identification antenna attached to the first major surface of the substrate, an integrated connected to the antenna circuit and a first composite layer comprising binder and a plurality of dispersed multilayered flakes in the binder, the multilayered flakes comprising two to about 100 layer pairs, each pair of layers comprising a crystalline layer of ferromagnetic metal adjacent a dielectric layer, and the layer pairs form a stack of alternating ferromagnetic metal layers with dielectric layers.
