A single-piece corrugated component, such as a feed horn, of an antenna includes a main body having a generally hollowed truncated pyramidal or conical shape which defines a body axis. The body extends from a base to an aperture, and includes a plurality of corrugations centered about the body axis, respectively. Each corrugation has a 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 10-60 degrees in a direction either toward the first end or the second end. A plurality of the frustopyramidal ridges have a respective inward virtual extension thereof crossing the body axis before intersecting the main body. A method of manufacturing the corrugated component includes the step of printing the component using an additive manufacturing technology.
