Abstract

We present low loss microstrip transmission line with compact transitions from coplanar waveguide for sub-terahertz applications. The microstrip (MS) transmission line is fabricated on the surface of a thin cyclic olefin copolymer dielectric layer. Among different optimization parameters, we present here the influence of CPW-to-MS transition length. Low loss transmission of the MS line has been demonstrated using Vector network analyzer (VNA) and its loss value is approximately -0.9 dB/mm. We also demonstrate that this topology is well suited for terahertz filters obtained by the combination of split rings resonators along the MS line.
