A theoretical and experimental study of a new type of monolithic planar transmission line is presented. This line can operate without the need for via holes or the use of air bridges for ground equalization. Furthermore, it has shown the tendency to radiate less than the conventional coplanar waveguide (CPW) and can provide a wide range of impedances due to the many available parameters for design. The space‐domain integral equation method is used to analyze several discontinuities of the proposed line. In order to validate the theory, measurements are performed on scaled models of a specific discontinuity. The experimental and theoretical results are in good agreement. In addition, it is demonstrated that the proposed line discontinuities radiate considerably less than the corresponding coplanar waveguide ones. © 1993 John Wiley & sons, Inc.
