Abstract
A radio frequency (“RF”) waveguide device fabricated by additive manufacturing is provided that includes a RF channel comprising a wall and a RF component comprising an unsupported span extending from the wall of the RF channel. The unsupported span can include at least one unsupported surface extending from the wall at an oblique angle relative to the wall. The RF component formed in this manner with additive manufacturing does not negatively impact the RF performance of the RF waveguide.

A radio frequency (“RF”) waveguide device, the RF waveguide device comprising:
- a RF channel comprising a wall;
- and
- a RF component comprising an unsupported span extending from the wall of the RF channel, the unsupported span comprising at least one unsupported surface extending from the wall at an oblique angle relative to the wall.
A method for forming a radio frequency (“RF”) waveguide device by additive manufacturing, the method comprising:
- fabricating a RF channel comprising a wall;
- and
- fabricating a RF component comprising an unsupported span extending from the wall of the RF channel, wherein the unsupported span is formed at least in part by building up at least one unsupported surface to extend from the wall at an oblique angle relative to the wall,
- wherein the unsupported span is fabricated without the use of an underlying supporting structure, wherein the unsupported span is completed using additive manufacturing without post processing machining.
