Waveguide hole lens structure

Abstract

A waveguide aperture lens structure has a lens body with six surfaces, one of which, a top surface and a bottom surface, are stepped surfaces, while the other four surfaces are planes. The lens body is permeated by a plurality of waveguide apertures arranged in an array with different cross-sectional sizes and shapes. One end of each waveguide aperture penetrates the top surface, and the other end of each waveguide aperture penetrates the bottom surface.

Claims

1. A waveguide aperture lens structure, comprising: A lens body has six surfaces, one of which, a top surface and a bottom surface, are each composed of multiple stepped surfaces forming a concave surface. The other four surfaces are flat. The lens body has multiple waveguide holes arranged in an array with different cross-sectional sizes and shapes. One end of each waveguide hole penetrates the top surface, and the other end penetrates the bottom surface. Each waveguide hole is a straight structure so that the waveguide direction is perpendicular. The waveguide hole lens structure can first set two or three virtual focal coordinates, then obtain a top surface position parameter, a bottom surface position parameter, and a phase change parameter through the virtual focal coordinates, and then set the length, width, and height of the waveguide hole based on the top surface position parameter, the bottom surface position parameter, and the phase change parameter.

2. The waveguide aperture lens structure as described in claim 1, wherein the concave surface is capable of changing the concave diameter of the concave surface by changing the height and / or shape of the plurality of stepped surface shapes, so that the concave surface is a curved surface.

3. The waveguide aperture lens structure as described in claim 1, wherein each stepped surface is perforated with a plurality of aligned waveguide apertures, each waveguide aperture having a rectangular through-hole.

4. The waveguide aperture lens structure as described in claim 1, wherein each stepped surface is perforated with a plurality of aligned waveguide apertures, each waveguide aperture having a circular perforation.

5. The waveguide aperture lens structure as claimed in claim 1, wherein each stepped surface is perforated by a transverse row of waveguide apertures, the waveguide apertures having a plate-shaped perforation.

6. The waveguide aperture lens structure as described in claim 1, wherein the lens body is made of a metallic material, a plastic material, a dielectric material, a magnetic material, or a synthetic metamaterial.
