Low cost instantly printed silver nano ink flexible dual-band antenna onto paper substrate

An instant and low cost inkjet-printed multiband Sierpinski fractal antenna onto a flexible paper substrate using chemically sintered silver nanoparticles ink is investigated in the present study. The printed layer is highly conductive, a few seconds after printing at room temperature, and without the need of special equipment or processes (a conventional inkjet printer is used to elaborate the antenna accurately. The antenna operates effectively in the 1.5-2.7 GHz and 5.1-11 GHz bands. It exhibits highly flexible mechanical properties enable it to be bent without sacrificing its performance. These promising results demonstrate the potential of utilizing instant printing technology for instantly and efficiently integrating antennas with flexible electronics and systems for the future wireless networks.
