Patent ID: 7498948

Claim:
A surveillance and/or identification device, comprising: a) an outer inductor having a first end coupled to a first plate of a first capacitor; b) an inner inductor having a first end coupled to a first plate of a second capacitor; c) a dielectric film on said outer inductor, said inner inductor, said first plate of said first capacitor and said first plate of said second capacitor, the first dielectric film having openings therein exposing second ends of each of the outer and inner inductors; d) a second plate of the first capacitor on the dielectric film, capacitively coupled to the first plate of the first capacitor; e) a second plate of the second capacitor on the dielectric film, capacitively coupled to the first plate of the second capacitor; f) a first conducting strap, configured to electrically connect a second end of the outer inductor to the second plate of the first capacitor; and g) a second conducting strap, configured to electrically connect a second end of the inner inductor to the second plate of the second capacitor.
