Using three dimensional (3-D) electromagnetic (EM) field simulations, a fully scalable grounded coplanar waveguide (GCPW) passive library was developed. It allows for all impedances between 28 and 68 Ohm. The library contains all coplanar elements needed for accurate millimeter-wave monolithic integrated circuit (MMIC) design, i.e. straight transmission lines, discontinuities, such as round bends, square corners, T- and cross junctions as well as quasi lumped components in coplanar environment, e.g. parallel and series metal-insulator-metal (MIM) capacitors. The library was simulated, modeled and verified up to 325 GHz. The models have been implemented in Agilent ADS allowing for fast and accurate designs in the millimeter-Wave (mmW) frequency range.
