ABSTRACT:
A method of fabricating a ridge waveguide filter having a slow-wave structure. The ridge waveguide is formed of a conductive sidewall-from metallic materials and may be in the form of a hollow tube, such as a rectangular hollow tube or a circular hollow tube, for example. The method comprises the steps of: forming a conductive body portion of an elongate hollow tube, wherein the body portion has an open top a bottom wall, two opposing side walls and an open top; providing a substrate having a top surface onto which a plurality of photoresist layers are formed; etching the top surface of the substrate to form a plurality of trenches in the substrate; plating the etched substrate surface with a layer of conductive material; and attaching the etched substrate to the conductive body portion to cover the open top of the conductive body portion.
