ABSTRACT:
The present invention describes An RFID antenna manufacturing system whereby the RFID antenna becomes an integral part of an integrated circuit package. The RFID manufacturing system contemplated by this invention includes photoresist manufacturing techniques to produce a template or die specifically designed to mass produce RFID transponders whereby the chip and antenna becomes one integrated unit. The RFID antenna template or die is precisely tuned, using trimming algorithms and laser technology, to resonate with electro magnetic signal increments of 2 megahertz. According to this system each electro magnetic signal increment is assigned to a different category in a supply chain. This invention reduces the cost, size and weight of prior art RFID transponders. This invention reduces signal to noise ratio by producing precisely tuned antennas which provide a gatekeeper function directly correlated to ambient electro magnetic signals.
