An improved coplanar transmission structure has a coplanar transmission line formed on one surface of a substrate and a lossy resistive material formed on the opposite surface of the substrate for suppressing spurious electromagnetic modes propagating through the substrate. The lossy resistive material may be nichrome or the like and is patterned on the substrate using thin or thick film processing.
