CAPACITOR STRAP
First Claim
1. A strap component for electrically bridging at least two respective portions of an antenna or coil component of an EAS or RFID tag or inlay, said strap component being a thin, generally planar member comprising a first electrically conductive planar element, a second planar electrically conductive element and a planar dielectric layer disposed between at least portions of said first and second electrically conductive planar elements, whereupon said strap component exhibits a desired capacitance, said first electrically conductive element including a first portion arranged to be secured in electrical continuity with one of the at least two respective portions of the antenna or coil, said second electrically conductive element including a first portion arranged to be secured in electrical continuity with another of the at least two respective portions of the antenna or coil.

Abstract
A capacitor strap that is applied to a security tag coil or antenna to form and properly tune an EAS or an RFID security tag. The capacitor strap is a thin film capacitor formed of two metal foils in between which is a dielectric material having ends that are electrically coupled to different points of a security tag coil or antenna. The capacitor strap may include an RFID integrated circuit, either in series or in parallel with the capacitor, which is then applied to security tag coil at a particular location to tune the tag to a predetermined frequency.
