Abstract
The present invention provides improved RFID antennae and tags and methods of manufacturing the RFID antennas. The RFID tags of the present invention include a substrate that comprises an antenna assembly. A radiofrequency integrated circuit is in electrical communication with a portion of the antenna assembly. The RFID tag may include a structure, such as a lid element, that clamps and/or compresses the radiofrequency integrated circuit into contact with the antenna assembly, without the need for a conductive adhesive. In some embodiments, the antenna assembly is vacuum metallized or otherwise applied onto the substrate through patterned openings in a mask, such as a patterned masking cliché or a patterned polymer layer.

18. A method of manufacturing a radiofrequency identification tag (RFID) or a portion thereof, the method comprising:
-
applying a conductive antenna onto a substrate;
positioning a radiofrequency integrated circuit over a portion of the conductive antenna; and
placing a protective element over the radiofrequency integrated circuit to at least partially surround the radiofrequency integrated circuit, wherein placing the protective element clamps the radiofrequency integrated circuit against the conductive antenna. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
