Radio frequency identification device and method
First Claim
1. A radio frequency identification (RFID) device comprising:
- a first flexible film of substantially uniform thickness having a first outer boundary;
a single integrated circuit (IC), comprising;
memory configured to store at least an identification number, a receiver configured to process a wireless interrogation signal, and a transmitter configured to provide a response to the wireless interrogation signal, the response including the identification number;
a dipole antenna coupled to both the receiver and the transmitter of the IC, the dipole antenna operable to receive the wireless interrogation signal and to supply the response; and
a second flexible film of substantially uniform thickness having a second outer boundary sealed directly to the first outer boundary of the first film to form a flexible package, wherein the IC and the dipole antenna are disposed between the first and second films.

Abstract
The present invention teaches a method of manufacturing an enclosed transceiver, such as a radio frequency identification (“RFID”) tag. Structurally, in one embodiment, the tag comprises an integrated circuit (IC) chip, and an RF antenna mounted on a thin film substrate powered by a thin film battery. A variety of antenna geometries are compatible with the above tag construction. These include monopole antennas, dipole antennas, dual dipole antennas, a combination of dipole and loop antennas. Further, in another embodiment, the antennas are positioned either within the plane of the thin film battery or superjacent to the thin film battery.
