Abstract
Provided herein are various enhanced arrangements for arrays of aperture antennas, such as horn antennas or short backfire antennas. Examples include an array of aperture antennas having a wall thickness between apertures, and a conductive mesh positioned above the apertures such that openings of the conductive mesh are aligned with the apertures and positioned having a selected spacing between the conductive mesh and the apertures.
Claims20
A system, comprising:
- an array of aperture antennas having walls defining individual apertures;
- a conductive mesh comprising a grid of conductive material having a pattern concordant with the apertures of the array;
- and
- the conductive mesh positioned above the apertures with a spacer material configured to align and offset the conductive mesh such that openings of the conductive mesh are aligned with the apertures and have a selected spacing between the conductive mesh and the apertures.

An apparatus, comprising:
- a conductive mesh comprising a grid of conductive material having a pattern concordant with apertures of an array of aperture antennas;
- and
- a frame coupled along a perimeter of the conductive mesh and configured to couple the conductive mesh at an offset distance from the apertures of the array of the aperture antennas and provide alignment between openings of the conductive mesh and the apertures.
A method, comprising:
- forming a conductive mesh comprising a grid of conductive material having a pattern concordant with apertures of an array of aperture antennas;
- and
- coupling the conductive mesh to a frame along a perimeter of the conductive mesh, wherein the frame is configured to provide alignment between openings of the conductive mesh and the apertures when the frame is applied to the array of the aperture antennas;
- establishing a spacing feature configured to provide an offset distance for the conductive mesh when the frame is applied to the array of the aperture antennas.
