A CAD Oriented Model of Elevated Coplanar Waveguide for Millimeter Wave Applications

In this paper the closed form analysis of Computer Aided Design oriented model for the characteristic impedance (z0) and the effective dielectric constant (ereff) of Elevated Coplanar Waveguide structures are obtained and performances are predicted using theoretical analysis. Numerically efficient and accurate formulae based on the conformal mapping method for the analysis of elevated coplanar waveguide structures are presented. Accurate closed form analysis formulas for Elevated Coplanar Waveguides are derived and verified with Matlab (7.0). These results have been compared with low loss MMIC rate race hybrid using Elevated Coplanar Waveguides.
