Improved performance of high frequency multilayer CPW inductors on flexible substrates

Abstract

Advantages in ink-jet printable electronics have opened the door for the manufacturing of sensors and actuators, radio-frequency identification (RFID) tags, wireless modules, photovoltaic, and displays [1, 2]. In this paper, we present the modelling, fabrication, measurement technique and characterization of multilayer miniature coplanar waveguide (CPW) meander type inductors for high frequency applications. CPW inductors are fabricated in inkjet printed technology on a flexible plastic polyimide foil (50 μm thickness) with Dimatix material printer DMP-3000. Inductors are made with silver nanoparticle ink which contains 20% wt of silver
