This article investigates the high frequency characteristics of coplanar waveguide (CPW) lines fabricated with inkjet-printing technology on BT substrates. The optimal metallic thickness of a printed CPW line is approximately estimated to be 3 μm. When printed lines with higher electrical conductivity are realized through additional surface preparation steps, the findings of this study suggest that the RF performance level of these printed lines will be comparable to that of the copper clad laminate lines in the microwave frequency region. Finally, aspects of such improvements as well as applications of these types of printed lines are discussed.
