Abstract Suspended coplanar waveguides have the advantage of both finline and suspended stripline.In this paper suspended coplanar waveguides are analyzed using conformal mapping techniques,and the exact solutions are obtained.Analytic closed-form expressions for the effective dielectric constant,the capacitance per unit length and the characteristic impedance of the suspended coplanar waveguides with finite thickness of dielectric substrate are given.
