Antenna for a Combination Eas/Rfid Tag with a Detacher
First Claim
1. A security device for detaching a combination electronic article surveillance (EAS) and radio frequency identification (RFID) tag (EAS/RFID tag), said security device comprising:
- a detacher configured to selectively disengage a clutch release disposed in a first portion of the combination EAS/RFID tag; and
a near field antenna substantially circular meander-like antenna configured to electronically read information stored in a second portion of the combination EAS/RFID tag, said near field antenna configured to substantially encircle said detacher and configured to read information from said second portion of the combination EAS/RFID tag at a position relative to said detacher when said second portion of said tag is disposed substantially tangentially relative to, and at any angle relative to, said detacher.

Abstract
A security device detaches a combination electronic article surveillance (EAS) and radio frequency identification (RFID) tag (EAS/RFID tag), and includes a detacher (magnet) to selectively disengage a clutch release disposed in a first portion of the combination EAS/RFID tag, a near field antenna configured to electronically read information stored in a second portion of the combination EAS/RFID tag. The antenna encircles the detacher and reads information from the second portion of the combination EAS/RFID tag at a position relative to the detacher when the second portion of the tag is disposed at any angle relative to the detacher and only when the detacher is positioned to disengage the clutch release. As long as the portion of the EAS/RFID tag containing the clutch end mechanism is located over the detaching magnet, the RFID label is in a valid detection zone regardless of its orientation relative to the antenna.
