This free coplanar waveguide (CPW) calculator calculates the optimal width of a waveguide line for a given characteristic impedance (Z0), based in the substrate geometry. It also calculates the effective permitivity εr eff, group delay and losses per unit of length.
The calculator can also determine the characteristic impedance of a line, for a given strip width.
Your calculated transmission line can be added to your Radio System Toolbox project, to be connected in your circuit and run simulations.
