Single-piece corrugated component of an antenna and method of manufacture thereof

A method for manufacturing a single-piece corrugated component of an antenna including a main body having a generally hollowed truncated pyramidal or conical shape defining a body axis, the main body extending from a first end to a second end, the main body including a plurality of corrugations centered about the body axis, respectively, each said plurality of corrugations having a frustopyramidal ridge adjacent a respective channel and defining side surfaces thereof, wherein each said frustopyramidal ridge having a respective inward virtual extension thereof crossing the body axis before intersecting the main body, and wherein the side surfaces of each said frustopyramidal ridge extending inwardly and locally perpendicularly from an inner surface of the main body at a ridge angle relative to the body axis varying between about ten and about sixty degrees (10°-60°) in a direction either toward the first end or the second end, said method comprising the step of printing said single-piece corrugated component using an additive manufacturing technology.
