The characteristics of the shielded suspended substrate coplanar waveguide(SSCPW) are analyzed by applying the point matchning method to the quasi-TEM mode approximation. The characteristic impedances and the effective dielectric constants are also calculated by changing the height of air and dielectric layer, and the strip width of SSCPW. Approaching the side strip width of SSCPW to zero, values of characteristic impedances and effective dielectric constants are agreed well with the results obtained by the variational method.
