Abstract
An RFID antenna for a container having an electroconductive container component is described. The RFID antenna comprises an antenna body having a surface comprising at least a portion of the electroconductive container component. The antenna body is shaped to define an antenna volume for receiving one or more RFID tagged items, and the antenna body forms a single turn solenoid. The RFID antenna further comprises at least one current feed point and at least one current return point, the feed and return points electrically connected to the antenna body so that a current flowing through the antenna body generates a magnetic field within the antenna volume for reading RFID tags.
Claims18
An RFID antenna for a container having an electroconductive container component, the RFID antenna comprising:
- an antenna body having a surface comprising at least a portion of the electroconductive container component,
- wherein the antenna body is shaped to define an antenna volume for receiving one or more RFID tagged items.
(canceled)
A tripartite RFID label adapted to be applied to an item having at least three adjacent surfaces, each surface in a different plane, the RFID label comprising:
- a flexible antenna substrate having three adjacent regions configured relative to one another so that, when applied around a vertex of the three adjacent surfaces in three planes, each of the three adjacent regions is associated with one of the three adjacent surfaces;
- an RFID antenna positioned one each of the three adjacent regions, each RFID antenna connected to an RFID chip,
- wherein each RFID antenna, when activated, has a magnetic field perpendicular to a respective one of the substrate regions so that, in use when the RFID label is applied to the item, each antenna's magnetic field is perpendicular to a respective item surface.
