Abstract
The present invention relates to methods of making capacitors for use in surveillance/identification tags or devices, and methods of using such surveillance/identification devices. The capacitors manufactured according to the methods of the present invention and used in the surveillance/identification devices described herein comprise printed conductive and dielectric layers. The methods and devices of the present invention improve the manufacturing tolerances associated with conventional metal-plastic-metal capacitor, as well as the deactivation reliability of the capacitor used in a surveillance/identification tag or device.
