Abstract
Approximate conformal mapping technique has been used for analysing the effect of finite substrate thickness on coplanar waveguide (CPW) theoretically. Calculations for impedance and effective dielectric constant are presented for CPWs with finite substrate thickness. Analytical formulations are presented for calculations. Network analytical methods of electromagnetic fields are employed to evaluate the effect of thick metal coating on CPW. Dispersion characteristics of CPW have been plotted for various metallization thicknesses. Effect of thick metal coating on attenuation is also plotted. Increase in metallization thickness of CPW causes an increase in wavelength; due to this fact characteristic impedance and effective dielectric constant decreases.
