发明名称 STABILIZED RESONANT TAG CIRCUIT AND DEACTIVATOR
摘要 The present invention is a stabilized resonant tag circuit (10) for use as an electronic article surveillance tag. The tag has a flexible substantially planar dielectric substrate (12) having conductors (20, 22) positioned on either side,.at least one of the conductors including an inductor (24). The tag is stabilized by a flexible, substantially planar, tear-resistant, substantially vapor impermeable polymeric film (26, 27) adhered to and covering at least one of the conductors and the substrate. The film provides a vapor barrier which minimizes the effects of body and article detuning on the circuit and promotes the secured integrity of the tag. The tag circuit may include an intended portion (36) in at least one of the conductors which permits the tag to be deactivated in response to an electromagnetic field of sufficient energy to destroy the resonant properties of the circuit.
