Abstract
An RFID tag or label or device includes an RFID chip and an antenna. The antenna is manufactured by weakening a portion of a foil material, which weakened portion may be in a tessellating pattern. The foil material is then placed in contact with adhesive on a substrate. The foil material and substrate are separated, so as to retain on the substrate the portion of the foil material in contact with the adhesive. The foil material remaining on the substrate defines an antenna, which may subsequently be electrically connected to an RFID chip to provide an RFID tag or label or device.
Claims19
A method for manufacturing an antenna for an RFID device, comprising:
- providing a foil material;
- forming a weakened portion in the foil material;
- providing a substrate having an adhesive;
- placing at least a portion of the foil material in contact with the adhesive of the substrate;
- and
- separating the foil material from the substrate so as to retain on the substrate the portion of the foil material in contact with the adhesive, thereby defining an antenna for an RFID device.
