High Frequency Characterization of Inkjet Printed Coplanar Waveguides

This work is focused on frequency domain electrical characterization of ink-jet printed coplanar waveguides (CPWs). The waveguides were designed and printed using conductive nanosilver ink at room temperature and sintered at 300degC. Distributed models, dependent on frequency, have been developed and some relevent parameters such as impedance, attenuation, are derived over frequency band from 30 kHz to 6 GHz. Two different widths of ground planes are investigated to examine the effects on CPW high frequency behaviors. In addition to these the obtained parameters have been compared and validated by theoretical calculations and momentum simulations.
