Patent ID: 8912890

Claim:
A surveillance and/or identification device, comprising: a) an electrically conducting strap on a substrate; b) a lower capacitor electrode on or over the substrate, electrically connected to the strap; c) a first dielectric film on the substrate and on or over a portion of the strap, the first dielectric film exposing a portion of the strap and having an opening over a portion of the lower capacitor electrode; d) a capacitor dielectric film on the lower capacitor electrode in the opening, the capacitor dielectric film having a significantly smaller thickness than the first dielectric film; e) an upper capacitor electrode on the first dielectric film and the capacitor dielectric film, the upper capacitor electrode capacitively coupled to the lower capacitor electrode; and f) an antenna and/or inductor electrically connected to the upper capacitor electrode and the strap.
