以高频射频识别和13.56 MHz ISM频率工作的全印刷射频(RF)收割机通常由一个小型印制环状天线组成。它们利用电感耦合在短距离内工作。本文介绍了一种新型的丝网印刷大面积电场天线，它与印刷有机二极管整流器相结合，在几米的距离内可以提供接近1V的直流电压和1W的输入。印刷有机二极管具有独特的高体积电容，无需额外的匹配组件即可实现与天线的有效虚阻抗匹配。结果表明，全印制射频能量采集器在高频下实现远距离工作是可行的。
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.
