Design and inkjet printing of RF devices in the GHz range

摘要

This paper presents a radio frequency filter fabricated on a low cost substrate by inkjet printing of a silver nanoparticles ink. This work focuses on the inkjet fabrication process and the setting of optimal printing conditions to achieve a band-pass filter working at 17 GHz. This RF filter is, to our knowledge, by far the highest center frequency inkjet printed filter reported up to now. It demonstrates the potential of inkjet printing technology for high frequency filtering applications.
