Abstract
Provided is a radio frequency identification (RFID) inlay comprising an antenna with a loop on a substrate; an integrated circuit (IC) connected to the loop, wherein the loop provides inductance for the IC, and wherein the antenna has an asymmetric design. The antenna comprises a cross hatch pattern comprising of connection lines to form rectangles, meander lines on one or more sides of the loop, or a solid bar on one or more sides of the loop.
Claims20
An RFID inlay comprising:
- a substrate defined by a first edge and a second edge opposing the first edge;
- and
- an antenna disposed on the substrate, wherein the antenna includes a loop and a first antenna pattern extending from the loop, wherein the loop is disposed adjacent to the first edge, and wherein the first antenna pattern is disposed between the loop and the second edge and is asymmetrical relative to the loop.
A label comprising:
- an RFID inlay with a substrate including a first edge and a second edge spaced apart from the first edge, wherein the substrate includes an integrated circuit and an antenna thereon, and wherein the antenna includes a loop and an antenna pattern extending from the loop, wherein the antenna pattern is disposed on a side of the loop and asymmetrical relative thereto;
- and
- a facestock disposed about the RFID inlay and in a stacked arrangement therewith, wherein the facestock comprises at least one of:
- an electronic product code, indicia, printed artwork, and information.
A method of preparing an RFID label comprising a printed facestock and a substrate with a leading edge and a rear edge, wherein the substrate includes an antenna thereon, said antenna including an antenna pattern, a loop, and an integrated circuit, wherein the integrated circuit is disposed adjacent a rear edge of the substrate, the method comprising:
- measuring a circumference of an item to which the RFID label will be applied;
- and
- determining a length between the leading edge and the rear edge based on the circumference to define an overlap portion such that the integrated circuit is disposed in the overlap portion and the printed facestock is not disposed in the overlap portion.
