Abstract :
Fast and exact analytic formulas for calcultaing the quasi-static-TEM parameters of a general broadside-coupled coplanar waveguide (GBSC-CPW) are presented. Simplicity, high speed of computation and exactness recommend their use for (M)MIC´S-CAD programs. Numerica1 calculations are presented in order to investigate various electrical properties of the structure. An asymmetrical BSC-CPW as well as the single CPW resulting from connecting the two coupled strips of the GBSC-CPW a the input and the output ports are also discussed. Criteria are obtained to ensure the coplanar behaviour of the structure.
