Title:

ADDITIVELY MANUFACTURED MESH HORN ANTENNA

Document Type and Number:

Japanese Patent JP2022058330

Kind Code:

A

Abstract:

To provide an efficient mesh horn antenna manufactured through a time- and cost-saving process, and a manufacturing method thereof.SOLUTION: An antenna device 210 includes an additively manufactured tubular body (a rectangular waveguide portion 216 and a pyramidal horn portion 218) having a wall 228 and a wall 230 provided with a plurality of holes. The tubular body transmits electromagnetic radiation in a selected operating frequency range, and has a mass below a maximum mass threshold. The holes reduce the mass of the tubular body to less than the maximum mass threshold without significantly adversely affecting electromagnetic radiation transmission capability of the tubular body in the selected operating frequency range.SELECTED DRAWING: Figure 3
