Abstract:
1. A surveillance and/or identification device, comprising: a) an outer inductor having a first end coupled to one of a first linear capacitor plate or a first nonlinear capacitor plate; b) an inner inductor having a first end coupled to the other of said first linear capacitor plate or said first nonlinear capacitor plate; c) a first dielectric film on said outer inductor, said inner inductor, said first linear capacitor plate and said first nonlinear capacitor plate, the first dielectric film having openings therein exposing second ends of each of the outer and inner inductors; d) a second linear capacitor plate on the first dielectric film, coupled to the first linear capacitor plate; and e) a second nonlinear capacitor plate on the first dielectric film, coupled to the first nonlinear capacitor plate; f) a second dielectric film containing holes therein for the second linear capacitor plate and the second nonlinear capacitor plate, and exposing the second ends of the outer and inner inductors; and g) first and second conducting straps on the second dielectric film, each configured to electrically connect one of the second inductor ends to a corresponding second capacitor plate.
