7.5–15 MHz organic frequency doubler made with pentacene-based diode and paper substrate

This work describes the realization of a fully organic “chip-less” tag, based on the harmonic RFID architecture, operating at 7.5 and 15 MHz. The tag is fabricated on paper substrate and includes an organic pentacene-based diode, as a non-linear component, to generate harmonics. The communication between reader and tag is provided by coupled resonators operating at the fundamental and harmonic frequencies. A measure campaign of the complete reader-tag system has been performed and the results are here reported.
