Abstract



An
existing analytical transmission line model to describe propagation
properties of coplanar waveguides including dispersion and radiation
effects was extended to take into account surface roughness of conductor
traces. The influence of parasitics is successively included in
the simulation and compared to measurements. The device under
test (DUT) was fabricated on an Al2O3 wafer. A metal and ceramic
chuck was utilized during measurements up to 120 GHz. The extended
model is then capable of precisely predicting propagation properties in a
wide frequency range and can now be used for calibration purposes like the
development of uncertainty budgets.
