Basic Parameters of Suspended Coplanar Waveguides

suspended coplanar waveguide have the adventages 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 expersessions for the effective dielectric constant,the capacitance per unit length and the characterisitic impedance of the suspended coplanar waveguides with dielectric substrate of finite thickness are given.
