Abstract
A radio frequency identification (RFID) inlay includes a conductive connection electrically connecting an antenna to strap leads that are coupled to an RFID chip. The conductive connection may include conductive bumps attached to the strap, and/or may include conductive traces, such as a conductive ink traces. The conductive connections provide a convenient, fast, and effective way to operatively couple antennas and straps. The RFID inlay may be part of an RFID label or RFID tag.
Claims83
A radio frequency identification (RFID) inlay comprising:
- an inlay substrate;
- an antenna on the inlay substrate;
- a strap, wherein the strap includes:
- an RFID chip having contacts thereupon;
- and
- strap leads operatively coupled to the contacts of the chip;
- a nonconductive adhesive attaching the strap to the inlay substrate;
- and
- a conductive connection operatively coupling the strap leads and the antenna;
- wherein the conductive connection includes conductive bumps attached to the strap.
