Code to add this calci to your website

Just copy and paste the below code to your webpage where you want to display this calculator.

Formula:

Where, ε_ff  = Effective Dielectric Constant. Zo =Characteristic Impedance. ε_r   = Relative Dielectric Constant. K(K₁),K(K₂),K(K₃)    = Elliptical integrals. K'(K₁),K'(K₂),K'(K₃) = Complements of  K(K₁),K(K₂) and K(K₃).

Dielectric Constant and Characteristic Impedance (Z0) calculation is done easier here using coplanar waveguide (CPW) calculator.
