The system of producing an RFID antenna using the silicon in an integrated
circuit as the resonant antenna material for the purpose of reducing the
cost of an RFID system and for the purpose of increasing the range and
selectivity of the RFID system. According to this invention the base
silicon sheets which make up the primary building material of the silicon
chip (integrated circuit) is subjected to a laser ablation process. This
creates three dimensional nano structures on the surface of the silicon
thereby raising its absorption rate of electro magnetic signals. On the
reverse side of the same silicon sheet a directional antenna is etched
using standard photographic reduction techniques and standard semi
conductor industry manufacturing methods. The two sides of the silicon
are connected through doping aluminum or copper impurities into these
same base silicon sheets causing conductivity within the sheet of
silicon.
