Abstract: 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.

Abstract: A feed horn and systems and methods of making and using the feed horn are presented. Exemplary feed horns include a first portion comprising a dual mode geometry and a second portion comprising an axial corrugation geometry. The feed horn may operate simultaneously in a plurality of separate frequency bands (e.g., from about 18.3 GHz to about 20.2 GHz and from about 29.1 GHz to about 30.0 GHz) and a plurality of separate waveguide modes (e.g., TE11, TM11 or HE11 modes); simultaneously operating over two bandwidth segments of at least 1900 MHz that are separated by at least 5000 MHz. The feed horn may have a short axial length (e.g. less than 4 wavelengths at 18.3 GHz), and it may be configured to operate in a prime fed offset reflector antenna system. In addition, the feed horn may be formed as a single piece via a single casting pull.

The horn comprises an outside sheet metal support on the inside of which is installed, one beside another, a great number of rings, having a shape such that two adjacent rings form a corrugation. Such structure enables economical manufacturing and facilitates adapting to various shapes of corrugations in the same horn.

Abstract: A microwave horn aerial is corrugated on its inner surface by being formed, e.g. by a screw cutting operation with a single start spiro helical groove or by moulding on a mandrel. In the latter case manufacture is relatively easy because the mandrel can be withdrawn by unscrewing it.

Abstract: A feed horn assembly includes a tubular horn body, a film and a sealing structure. The tubular horn body has a first end and an opposite, second end. The first end includes a peripheral groove defined by an inner peripheral portion and an outer peripheral portion. The film covers the first end. A peripheral bending portion and a periphery portion of the film are disposed inside the groove. The sealing structure is disposed in the groove, and includes a first sealing component urging against the peripheral bending portion and the periphery portion of the film, and a second sealing component urging against the peripheral bending portion and the first sealing component. The outer peripheral portion has a peripheral chamfer portion formed by crimping. The peripheral chamfer portion urges against the sealing structure, such that a sealed condition is formed between the film and the inner peripheral wall.

Abstract: In the disclosed method for fabricating corrugated microwave components, a billet assembly is formed of electrically conductive plates sandwiched with chemical etching sensitive spacer material and clamped together. An inside surface is formed in the billet and a mandrel inserted. An outer contoured surface is then formed on the mandrel-billet assembly. The outer surface is then plated to a desired thickness. The mandrel is removed and the spacers chemically etched away leaving the finished component. With the disclosed method, microwave device fabrication for frequencies including 100 GHz and higher is possible.

Abstract: A dual waveguide horn antenna is provided with a rigid foam having a dielectric constant approximately equal to that of air and tapered to conform to the shape of a conventional horn antenna. Two tapered walls are corrugated and all four walls are covered with a thin metallic coating of sufficient thickness to carry the RF current produced by the propogation of an electromagnetic wave through the dielectric. A metallic septum divides the dielectric into first and second waveguide sections and individual coaxial inputs are provided to each of the sections. Energy coupling between the two sections of the waveguide are significantly reduced by means of a microwave resistive material secured to the septum at the enlarged end of the dielectric. The resistive strip may comprise a carbonized substrate or an insulating material coated with the resistive film. Additionally, a thin film of paint may be applied directly to the metallic septum by various techniques including vacuum deposition.
