COMBINATION EAS AND RFID SECURITY TAG HAVING STRUCTURE FOR ORIENTING A HYBRID ANTENNA RFID ELEMENT

摘要

A security tag (10) including independent EAS (16) and RFID (18) components disposed in a housing (12) configured for geometric placement of the RFID and EAS components for optimum RFID performance. The EAS component (16) is situated in a first compartment (17) and the RFID component (18) is situated in a second compartment (19). The RFID component includes a hybrid antenna RFID inlay (24) and an IC chip (30). The tag housing (12) includes a key structure (38) that minimizes the de-tuning of both the EAS (16) and RFID components (18) by positioning the IC chip (30) such that the IC chip (30) is closer to a first side (25) of the second compartment (19) than the second side (21) of the second compartment (19) when the antenna inlay (24) is inserted within the housing (12). The housing (12) further includes one or more pins that position the RFID inlay (24) closer to the bottom interior surface to further insure optimal RFID read performance.
