Abstract : The patent describes utilizing photo resist techniques to apply a microstrip circuit to a soluble or etchable substrate having a thin film conductor on at least one surface. After formation of the circuit the photo resist is removed, and the circuit arc-plasma sprayed, subsequently, the original substrate is removed. Another embodiment causes the area from which the original substrate has been removed to be arc-plasma sprayed thereby causing the circuit to be encapsulated. Another embodiment plates the outside surface of the encapsulated circuit to achieve a TEM mode of propagation.
