Detailed Implementation

[0024] The router proposed in this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that the drawings are all in a very simplified form and use non-precise scales, and are only used to facilitate and clarify the explanation of the embodiments of this utility model. Furthermore, the structures shown in the drawings are often part of the actual structure. In particular, different drawings may emphasize different aspects and sometimes use different scales.

[0025] This invention includes a radiating antenna and a metamaterial lens, wherein the radiating antenna and the metamaterial lens are arranged parallel to each other; the metamaterial lens includes a housing and a metal circuit board assembly, wherein the metal circuit board assembly is placed in a cavity formed by the housing, and the metal circuit board assembly is polarized under the radiating magnetic field generated by the radiating antenna to enhance the radiating electromagnetic field of the radiating antenna.

[0026] The housing includes a first outer shell and a second outer shell, which are interlocked to form the accommodating cavity. The metal circuit assembly includes a first metal circuit board, a second metal circuit board, and a third metal circuit board, which are arranged parallel to each other at intervals. Each of the first, second, and third metal circuit boards is rectangular, and each metal circuit board has several rectangular metal wires. Each of the first, second, and third metal circuit boards includes the metal wires and a metal wire carrier, with the metal wires disposed on the metal wire carrier. All the metal wires are configured as copper foil.

[0027] This invention provides a router, which includes an antenna module comprising a first antenna assembly and a second antenna assembly, both mounted on a substrate. The first antenna assembly includes a first radiating antenna 10A and a first metamaterial lens 20A, which are placed parallel to each other. The second antenna assembly includes a second radiating antenna 10B and a second metamaterial lens 20B, which are also placed parallel to each other. The first radiating antenna 10A and the second radiating antenna 10B are perpendicular to each other, as are the first metamaterial lens 20A and the second metamaterial lens 20B. The first metamaterial lens 20A and the second metamaterial lens 20B are polarized under the respective radiating magnetic fields generated by the first radiating antenna 10A and the second radiating antenna 10B, thereby enhancing the electromagnetic field in the respective radiating directions of the first radiating antenna 10A and the second radiating antenna 10B.

[0028] This configuration, where the first radiating antenna 10A and the second radiating antenna 10B are respectively paired with the first metamaterial lens 20A and the second metamaterial lens 20B, means that the first metamaterial lens 20A and the second metamaterial lens 20B are polarized under the respective radiating magnetic fields generated by the first radiating antenna 10A and the second radiating antenna 10B. This effectively enhances the electromagnetic field in the respective radiating directions of the first radiating antenna 10A and the second radiating antenna 10B. Because the electromagnetic wave forms an enhanced electric field in the direction of propagation, the overall antenna radiation gain within the router is significantly improved. In this invention, the first radiating antenna 10A and the second radiating antenna 10B are perpendicular, and the first metamaterial lens 20A and the second metamaterial lens 20B are mutually perpendicular. This increases the direction of antenna radiation, thereby enhancing the overall radiation performance of the router.

[0029] It should be noted that metamaterials are substances with negative refractive indices, also known as metamediums. Metamaterials can be classified into double-negative metamaterials, which have both negative dielectric constants and permeability; magnetically single-negative metamaterials, which have negative permeability; and electrically negative metamaterials, which have negative dielectric constants. The metamaterial lens in this invention is a special lens formed by the polarization of a metal circuit under the influence of an applied electromagnetic field. It is designed based on the concept of metamaterials, which are composed of artificially designed subwavelength structural units. These units typically possess special electromagnetic properties, such as negative refractive index or zero refractive index.

[0030] Furthermore, both the first metamaterial lens 20A and the second metamaterial lens 20B are configured as rectangular metamaterial lenses, each including a first outer shell 21, a second outer shell 22, and a metal circuit board assembly. The first outer shell 21 and the second outer shell 22 form a cavity, and the metal circuit board assembly is placed inside the cavity. This configuration protects the internal metal circuit board through the cavity formed by the first outer shell 21 and the second outer shell 22. The metal circuit board assembly includes a first metal circuit board 23, a second metal circuit board 24, and a third metal circuit board 25 that are parallel to each other in sequence. The first metal circuit board 23 and the third metal circuit board 25 are respectively attached to the inner walls of the first outer shell 21 and the second outer shell 22. With this configuration, the metal circuits on the metal circuit board are polarized under the influence of the magnetic field radiation of the radiating antenna, and the electromagnetic wave forms an enhanced electric field in the direction of propagation, thereby improving the gain effect in the radiation direction generated by the radiating antenna.

[0031] Specifically, the edge of the first outer shell 21 has a stepped recessed platform 210. The second metal circuit board 24 is placed on the recessed platform 210, forming a first gap between it and the first metal circuit board 23. The second outer shell 22 is fastened to the first outer shell 21, and a second gap is formed between the second metal circuit board 24 and the third metal circuit board 25. The first metal circuit board 23 and the third metal circuit board 25 are respectively adhered to the inner walls of the first outer shell 21 and the second outer shell 22 with double-sided adhesive. The spacing values ​​of the first gap and the second gap are the same. Preferably, the range of the spacing values ​​of the first gap and the second gap is 3mm ± 0.01.

[0032] Preferably, the first metal circuit board 23, the second metal circuit board 24, and the third metal circuit board 25 are all rectangular, and each metal circuit board has a plurality of metal wires 26. The metal wires 26 are rectangular, and each of the metal wires 26 is configured as copper foil; the plurality of metal wires 26 are disposed on a metal wire carrier 27. In the horizontal direction, the plurality of metal wires 26 are spaced apart and located in a straight line; in the vertical direction, the plurality of metal wires 26 are spaced apart and parallel to each other. That is to say, the first metal circuit board 23, the second metal circuit board 24, and the third metal circuit board 25 of this invention are all rectangular in shape, and the metal wires 26 on each metal circuit board are also arranged in a rectangular shape, wherein the metal wires 26 are copper foil with good conductivity, and the thickness is preferably 12um±0.01. The carrier on the metal wires 26 is PI or PET with a low dielectric constant and a thickness of 25um±0.01. It should be noted that the vertical direction is the length direction of each metal circuit board, and the distance between the metal wires 26 in the length direction of the metal circuit board is 0.5mm ± 0.01mm; the horizontal direction is the width direction of each metal circuit board, and the distance between the metal wires 26 in the width direction of the metal circuit board is 0.3mm ± 0.01mm. Preferably, the length of each metal wire 26 is 3mm. It should also be noted that the number of metal circuit boards can be more than three or less. In this utility model, three metal circuit boards are preferred as the most effective number. Therefore, this utility model does not impose any limitation on the number of metal circuit boards.

[0033] Preferably, in this invention, both the first radiating antenna 10A and the second radiating antenna 10B are configured as PCB antennas. The arrangement direction of the first radiating antenna 10A and the first metamaterial lens 20A, and the arrangement direction of the second radiating antenna 10B and the second metamaterial lens 20B, correspond to the same direction. Thus, the arrangement direction of the metal wires 26 on the corresponding metal circuit board is also the same as the placement direction of the corresponding radiating antenna, ensuring that the metal circuit is parallel to the electric field direction of the corresponding radiating antenna. Of course, the metal wires 26 on the metal circuit board can be parallel to each other (upper and lower lines) or vertically parallel, as long as the parallelism between the metal wires 26 and the radiating electric field of the radiating antenna is ensured; no further restrictions are imposed.

[0034] It should be noted that in this invention, the metamaterial lens polarizes the metal circuitry under the influence of an external electromagnetic field, and several metal wires 26 polarize under the influence of the electromagnetic field generated by the radiating antenna, thereby enhancing the electromagnetic field in the respective radiation directions of the first radiating antenna 10A and the second radiating antenna 10B, thus increasing the radiation gain of the antenna. As shown in the figure, it can be seen that the gain of a single radiating antenna and the antenna with the first metamaterial lens 20A and / or the second metamaterial lens 20B increases slightly at different frequencies, but the gain increase is greater than 2 dBi across the entire frequency band.

[0035] In summary, this utility model provides a router comprising an antenna module, which includes a first antenna assembly and a second antenna assembly, both mounted on a substrate. The first antenna assembly includes a first radiating antenna 10A and a first metamaterial lens 20A, placed parallel to each other. The second antenna assembly includes a second radiating antenna 10B and a second metamaterial lens 20B, also placed parallel to each other. The first and second radiating antennas 10A and 10B are perpendicular to each other, as are the first and second metamaterial lenses 20A and 20B. The first and second metamaterial lenses 20A and 20B are polarized under the respective radiating magnetic fields generated by the first and second radiating antennas 10A and 10B, respectively, thereby enhancing the electromagnetic field in their respective radiating directions. This utility model's router not only maintains a simple internal structure but also effectively improves the overall antenna gain.

Similar or identical parts between embodiments can be referred to mutually. In addition, the different parts between embodiments can also be combined with each other, and this utility model does not limit this.
