Abstract: The combination of a pusher dispenser having a coil spring resiliently urging a plate towards a front of the dispenser, a track for guiding the plate, a bottom surface along the track, and an electrically non-conductive insert supported by the bottom surface and having a length, a plurality of RFID tags attached to the insert along its length, the insert supporting the RFID tags at a level adjacent and below an extension of the coil spring whereby an extension of the coil spring is effective to shield the RFID tags from a reader.

Abstract: An RFID antenna having two flexible elongated conductive transmission lines with coplanar RFID energy radiation perturbations distributed along the transmission lines, the transmission lines and perturbations being folded between ends of the transmission lines so that the transmission lines of one fold overlie and are adjacent the transmission lines of the other fold and an electrically insulating layer disposed between lengths of the transmission lines on either side of the fold.
