Abstract
Techniques for an RFID device with improved multi-axis performance are provided. The device includes a flexible substrate with an antenna pattern formed thereon. A fold in the flexible substrate results in the antenna pattern crossing over itself and disposes a distal region of the antenna pattern away from a proximal region at about a predetermined angle. An integrated circuit is electrically coupled to the antenna pattern. In a specific embodiment, the antenna pattern is slit along a major axis to allow folding a segment of an antenna pattern.
Claims16
An RFID device comprising:
- a flexible substrate;
- an antenna pattern formed on the flexible substrate, the antenna pattern having a major axis from a distal region to a proximal region;
- a fold in the flexible substrate whereby the antenna pattern crosses over itself, the fold disposing the distal region away from the major axis from the proximal region at about a predetermined angle with the major axis;
- and
- an integrated circuit electrically coupled to the antenna pattern.
A method for manufacturing an RFID tag, the method comprising:
- providing a web comprising a plurality of RFID inlays, each of the plurality of RFID inlays including:
- an antenna, the antenna having a major axis from a first end to a second end, and
- an integrated circuit electrically coupled to the antenna;
- slitting at the first end along the major axis each antenna to form a partly detached first antenna portion;
- singulating the plurality of RFID inlays;
- folding the first antenna portion of each antenna.
An RFID label comprising:
- a facestock layer;
- an adhesive layer;
- and
- an RFID inlay comprising:
- a flexible substrate;
- an antenna pattern formed on the flexible substrate, the antenna pattern having a major axis from a distal region to a proximal region;
- a fold in the flexible substrate whereby the antenna pattern crosses over itself, the fold disposing the distal region away from the major axis from the proximal region at about a predetermined angle;
- and
- an integrated circuit electrically coupled to the antenna pattern.
A system comprising:
- an interrogator to transmit an interrogating RF signal, the interrogator including an antenna and transceiver;
- and
- a tag storing identifier information, the tag including:
- an antenna formed on a flexible substrate, wherein the antenna comprises a major axis from a proximal region to a distal region of the antenna;
- a fold in the flexible substrate disposing away the distal region of the antenna from the major axis from the proximal region of the antenna at about a predetermined angle with the major axis;
- and
- an integrated circuit electrical y coupled to the antenna.
