| Popis: | Fully printed radio frequency (RF) harvesters that operate at HF RFID and ISM frequency of 13.56 MHz are normally comprised of a small printed loop antenna. They work at short ranges using inductive coupling. In this paper, we present a novel screen printed large area E-field antenna incorporated with a printed organic diode rectifier that can provide close to 1 V dc voltage with 1 W input at a distance of a few meters. The unique high bulk capacitance of the printed organic diodes enables effective imaginary impedance matching to the antenna without an additional matching component. The results demonstrate the possibility of fully printed RF energy harvesters for long range operation at HF frequencies. |
