RFID tag having a silicon micro processing chip for radio frequency identification and a method of making the same
First Claim
1. A RFID device comprising:
- a silicon micro processing chip having a first antenna disposed on a substrate; and
at least one secondary antenna disposed on said substrate, said first antenna being disposed within coupling distance of said at least one secondary antenna in an insulated manner to form a RF inlet, wherein when said RF inlet is placed in proximity to a transmitting and receiving antenna of a RFID system said transmitting and receiving antenna transmits an output signal to said at least one secondary antenna, and said at least one secondary antenna transmits said output signal to said first antenna to provide an electromagnetic connection therebetween.

Abstract
A RFID device includes a silicon micro processing chip having an IC antenna disposed on a substrate or other surface, such as a label, tag or coin. At least one secondary antenna is also positioned on the substrate. The IC antenna of the chip is positioned within a coupling distance of the at least one secondary antenna in an insulated manner to form a RF inlet. When the RF inlet is placed in proximity to a transmitting and receiving antenna of a RFID system, the transmitting and receiving antenna transmits an output signal to the secondary antenna, and the secondary antenna in turn transmits the output signal to the IC antenna to provide an electromagnetic connection therebetween. The signals of IC antenna and secondary antenna are tuned to emit a uniform return signal that is received by the antenna of the RFID system to transfer data from the chip hereto.

20. A method of forming a RFID device, comprising the steps of:
-
providing a silicon micro processing chip, said silicon chip having a first antenna;
positioning at least one secondary antenna on a substrate;
positioning said silicon micro processing strip on said substrate such that said first antenna is within a coupling distance of said at least one secondary antenna to form an RF inlet, said first and secondary antennas being insulated from each other, providing a RFID system, said RFID system including a transmitting and receiving antenna;
positioning said RF inlet of said chip in the proximity of said RFID system; and
transmitting an output signal from said transmitting and receiving antenna such that said at least one secondary antenna receives the output signal and couples with the first antenna to provide a return signal that is received by the transmitting and receiver antenna of said RFID system to transfer data from the silicon micro processing chip to the RFID scanner. - View Dependent Claims (21, 22, 23, 24)
