Abstract
A combination EAS/RFID antenna for use in an EAS/RFID surveillance system. The antenna includes an EAS antenna element and an RFID antenna element. The EAS antenna element includes an EAS loop antenna defining an interior area. The RFID antenna element is positioned within the interior area defined by the EAS loop antenna and includes a ground plane and RFID patch antenna. The ground plane and/or the RFID patch antenna have a segmented conductor pattern etched thereon. The segmented conductor pattern minimizes eddy currents in the ground plane produced by current flow through EAS loop antenna. The RFID antenna element is situated proximate the EAS loop antenna in such a fashion that the overall size of the antenna is reduced.
