Abstract

A digital system has a substrate having a top surface on which a waveguide is formed on the top surface of the substrate. The waveguide is formed by a conformal base layer formed on the top surface of the substrate, two spaced apart sidewalls, and a top conformal layer connected to the base layer to form a longitudinal core region. The waveguide may be a metallic or otherwise conductive waveguide, a dielectric waveguide, a micro-coax, etc.

First claim

What is claimed is:

1. A method for forming a waveguide, the method comprising:
forming a conformal base layer for the waveguide on a surface of a substrate;
forming an elongated core region for the waveguide on the base layer;
forming sidewalls and a conformal top layer surrounding the elongated core region and in contact with the base layer;
wherein the base layer, the core region, the sidewalls, and the top layer are formed by three dimensional printing onto the surface of the substrate;
wherein the conformal base layer is formed to match a footprint of the waveguide.
