Description

Technical Field

[0001] This utility model relates to the field of microwave antenna technology, and in particular to a microwave antenna beam focusing device based on hyperbolic metamaterial. Background Technology

[0002] Microwave antennas are the core component of microwave communication systems, and their function is to achieve spatial transmission of signals through the transmission and reception of electromagnetic waves.

[0003] In the prior art, patent document with publication number (CN201210268796.X) mentions a microwave antenna with a metal hyperboloid and an ellipsoidal metamaterial as its sub-reflector. It utilizes a metal hyperboloid and a planar metamaterial equivalent to a rotating elliptical surface as sub-reflectors to perform multiple reflections, thereby broadening the beam and adjusting the energy distribution on the aperture surface, thus increasing the antenna's aperture.

[0004] Traditional microwave antennas suffer from insufficient beam control precision and lack of control capability. Utility Model Content

[0005] The purpose of this invention is to provide a microwave antenna beam focusing device based on hyperbolic metamaterials, which solves the problems of insufficient beam control accuracy and lack of control capability in traditional microwave antennas.

[0006] To achieve the above objectives, this utility model provides a microwave antenna beam focusing device based on hyperbolic metamaterials, comprising a plurality of S-band array units, a plurality of X-band array units, a SiO2 silica metamaterial panel, and oxygen-free copper. The oxygen-free copper is fixedly connected to the SiO2 silica metamaterial panel and located below the SiO2 silica metamaterial panel. The plurality of X-band array units are fixedly connected to the oxygen-free copper and the SiO2 silica metamaterial panel and are uniformly arranged above the oxygen-free copper and the SiO2 silica metamaterial panel. The plurality of S-band array units are fixedly connected to the SiO2 silica metamaterial panel and are uniformly arranged above the SiO2 silica metamaterial panel. On the surface, each of the S-band array units includes an S-band array unit Au gold layer, an S-band array unit graphene layer, and an S-band array unit Si silicon layer. The S-band array unit Si silicon layer is fixedly connected to the SiO2 silicon dioxide metamaterial panel and is uniformly disposed on the surface of the SiO2 silicon dioxide metamaterial panel. The S-band array unit graphene layer is fixedly connected to the S-band array unit Si silicon layer and is disposed above the S-band array unit Si silicon layer. The S-band array unit Au gold layer is fixedly connected to the S-band array unit graphene layer and is disposed above the S-band array unit graphene layer.

[0007] The S-band array unit Au gold layer, the S-band array unit Graphene layer, and the S-band array unit Si silicon layer are all arranged in a square shape with a width of 7.5 cm, and the spacing between two adjacent S-band array units is 7.5 cm.

[0008] The width of the X-band array unit is 2.5cm, and the distance between two adjacent X-band array units is 15cm.

[0009] This invention discloses a microwave antenna beam-focusing device based on hyperbolic metamaterials. The X-band and S-band array units are responsible for focusing and receiving or transmitting electromagnetic waves within their respective frequency bands. A silicon dioxide layer and an oxygen-free copper substrate provide support and electrical isolation for the entire structure. By adjusting the properties of the graphene layer and the dielectric constant of the silicon layer, the beam-focusing performance of the array can be optimized. The Au layer of the S-band array unit serves as a conductive layer, primarily used to improve surface conductivity, reduce resistance loss, and act as a supporting substrate for the graphene layer. The graphene layer of the S-band array unit possesses excellent conductivity and mechanical strength. In microwave applications, graphene can be used to modulate surface impedance, thereby controlling the propagation characteristics of electromagnetic waves. The Si layer of the S-band array unit serves as the substrate material, providing structural support. Attached Figure Description

By adjusting the characteristics of the graphene layer and the dielectric constant of the silicon layer, the beam focusing performance of the array can be optimized. The Au gold layer 1 of the S-band array unit serves as a conductive layer, mainly used to improve surface conductivity, reduce resistance loss, and act as a supporting substrate for the graphene layer.
