Crossed dipole frequency doubling RFID TAG based on paper substrate and ink-jet printing technology

A frequency doubler TAG structure realized on both plastic and paper is presented. It is based on the crossed dipole structure, but uses four diodes in a bridge configuration to form a balanced multiplier layout and incorporates the necessary DC path in a simple way within the structure. Measurements results are presented for both the plastic and paper structure, showing the feasibility of economic and green electronics on paper.
