[0038] Example 1
[0039] The gain adjustment device in this embodiment is applied to a communication system and used in conjunction with the antenna in the communication system to achieve the purpose of increasing gain. Specifically:
[0040] like Figure 1 As shown, the gain adjustment device of this embodiment includes a main structure 1, a first substrate layer 2 and a second substrate layer 3. The main structure 1 includes a housing 4 and a third substrate layer 5 inside the housing 4. The first substrate layer 2 and the second substrate layer 3 are disposed on the outer surface of the housing 4 and located on opposite sides. The first substrate layer 2, the second substrate layer 3 and the third substrate layer 5 are arranged in parallel.
[0041] The first substrate layer 2, the second substrate layer 3, and the third substrate layer 5 all include a gain adjustment layer, which is positioned toward the antenna in the communication system.
[0042] Based on the coordinated design of the above structures, combined with the setting of the gain adjustment layer, the gain adjustment device can achieve the purpose of improving antenna gain, enhancing antenna signal, and improving signal penetration and coverage.
[0043] In this disclosure, by optimizing the design of the gain adjustment device, corresponding substrate layers are set inside and outside the main structure 1 respectively. Once powered on, each substrate layer is polarized under the influence of the applied electromagnetic field, and the electromagnetic wave forms an enhanced electric field in the direction of propagation, thereby increasing the gain in that direction. This achieves the purpose of enhancing gain, increasing antenna signal penetration, and expanding antenna coverage, resulting in wider communication range, smoother network speed, and lower signal latency, greatly enhancing the user experience. At the same time, this gain adjustment device is not limited by the size of the antenna and can be flexibly and conveniently connected to the antenna without modifying the existing antenna, exhibiting strong adaptability and compatibility with the usage needs of more scenarios. In addition, this gain adjustment device also has the advantages of low cost, simple structure, easy manufacturing, and easy installation.
[0044] Example 2
[0045] like Figure 2 As shown, the gain adjustment device in this embodiment is a further improvement on Embodiment 1, specifically:
[0046] In one feasible embodiment, the housing 4 includes a first cover 6 and a second cover 7, a first substrate layer 2 is disposed on the outer surface of the first cover 6, and a second substrate layer 3 is disposed on the outer surface of the second cover 7.
[0047] The first cover 6 and the second cover 7 of the housing 4 are covered together, and the third substrate layer 5 is disposed between the first cover 6 and the second cover 7.
[0048] The gain adjustment device also includes a first protective layer 8 and a second protective layer 9. The first protective layer 8 covers the surface of the first substrate layer 2 to protect the first substrate layer 2, and the second protective layer 9 covers the surface of the second substrate layer 3 to protect the second substrate layer 3.
[0049] In this disclosure, the first protective layer 8 and the second protective layer 9 respectively shield and protect the first substrate layer 2 and the second substrate layer 3, so as to avoid long-term exposure to the environment or to avoid adverse effects or even damage to the first substrate layer 2 and the second substrate layer 3, thereby ensuring the stability and reliability of the gain effect of the gain adjustment device.
[0050] In one feasible embodiment, the first substrate layer 2 and / or the second substrate layer 3 are spray-coated layers applied by a metallization process.
[0051] In this disclosure, the first substrate layer 2 and the second substrate layer 3 are metallized using methods such as copper clad laminate etching, addition method, metal pad printing, metal inkjet printing, metal printing, conductive ink printing, in-mold injection molding, and vacuum plating, and are disposed on the outer surfaces of the corresponding first cover 6 and second cover 7. At this time, the first cover 6 and the second cover 7 serve as the carriers of the first substrate layer 2 and the second substrate layer 3, so that the first substrate layer 2 and the second substrate layer 3 are supported. This facilitates manufacturing and also has the advantages of simple structure, small space occupation, and low cost.
[0052] In one feasible embodiment, the first protective layer 8 and / or the second protective layer 9 are spray-coated layers applied by a paint spraying process.
[0053] In this disclosure, the first protective layer 8 and the second protective layer 9 are paint spraying layers, which are sprayed on the outer surfaces of the first substrate layer 2 and the second substrate layer 3. The coverage area of the first protective layer 8 and the second protective layer 9 should cover the entire first substrate layer 2 and the second substrate layer 3 in order to achieve a better protective effect. The paint spraying method is both convenient and can achieve reliable protection for the first substrate layer 2 and the second substrate layer 3. The color and thickness of the sprayed paint can be determined or adjusted according to the actual situation.
[0054] In one feasible embodiment, the third substrate layer 5 is connected to the first cover 6 via the first fastener 10; the third substrate layer 5 is connected to the second cover 7 via the second fastener.
[0055] In this disclosure, the third substrate layer 5, located between the first cover 6 and the second cover 7, is connected to the corresponding cover by a fastener to achieve its own fixation, ensure reliable cooperation between different structures, achieve the stability of the overall structure, and ensure the structural stability and reliability of the entire device.
[0056] In one feasible embodiment, the first fastener 10 / second fastener 11 includes a double-sided adhesive layer or a snap-fit structure;
[0057] In this disclosure, the third substrate layer 5 can be fixed to the first cover 6 and the second cover 7 by means of double-sided adhesive or clips. The use of double-sided adhesive is the preferred method, which has the advantages of simple structure, easy implementation and convenient disassembly and reuse. Of course, other fixing methods can also be used, which will not be described in detail here.
[0058] In one feasible embodiment, the dielectric constant of the first cover 6 is less than the dielectric constant of the first substrate layer 2; and / or, the dielectric constant of the second cover 7 is less than the dielectric constant of the second substrate layer 3.
[0059] In the present disclosure, the first cover 6 and the second cover 7 can be made of an insulating material with a low dielectric constant such as plastic, and serve as carriers for the first substrate layer 2 and the second substrate layer 3. The first substrate layer 2 and the second substrate layer 3 are conductors with a high dielectric constant. Specifically, the first substrate layer 2 and the second substrate layer 3 are metal layers. Thus, through the optimized structural design, it is ensured that the gain adjustment device has the effects of gain enhancement, enhancing the penetration of antenna signals, and increasing the antenna coverage range.
[0060] Based on the above, the gain adjustment device of this embodiment is formed in the following manner:
[0061] As Figure 3 shown, the gain adjustment device of this embodiment consists of a first protective layer 8, a first substrate layer 2, a first cover 6, a third substrate layer 5, a second cover plate, a second substrate layer 3, and a second protective layer 9, which are sequentially stacked on top of each other to form a compact and stable structure. As Figure 4 shown in
[0062] In an implementable solution, the electric field direction formed in the gain adjustment layer is parallel to the electric field direction of the electromagnetic wave in the preset direction;
[0063] Among them, the gain adjustment layer includes a plurality of metal wires arranged in a preset layout manner, that is, different forms of gain adjustment layers can be set as long as they can achieve a high gain effect.
[0064] Among them, the material of the metal wire includes highly conductive materials such as copper, silver paste, tin, or conductive ink. Of course, the gain adjustment layer can also be made of a variety of highly conductive materials.
[0065] In an implementable solution, the metal wire includes a metal wire with a regular shape or an irregular shape;
[0066] Specifically, the regular shape includes a rectangle, a square (see Figure 5 , square shape, where, Figure 5 E is the electric field direction), a triangle, a circle, an ellipse, a rhombus, a polygon, a cross shape (such as a "plus" shape, see Figure 6 , a "times" shape, see Figure 7 , a "hui" character shape, etc.); among them, Ex and Ey are the electric field directions.
[0067] The irregular shape includes any other irregular shape except the regular shape; for example, a circle along the preset direction is provided.
[0068] The gain adjustment layer includes a number of metal wires arranged in parallel and spaced intervals along a first preset direction and arranged in spaced intervals along a second preset direction; for example, the gain adjustment layer is composed of a number of rectangular metal wires with a certain length, a certain width and a certain distance.
[0069] Specifically, the density of each metal wire in the first preset direction and the second preset direction can be designed or adjusted according to actual needs.
[0070] The overall dimensions of the substrate layer can be determined based on factors such as the dimensions of the communication device and the distance from the communication device. The design of several metal wires can also be adapted to the overall dimensions of the substrate structure.
[0071] In this disclosure, a planar structure is formed by arranging a number of metal wires that are arranged parallel and spaced apart along a first preset direction and spaced apart along a second preset direction. The electric field direction formed by this planar structure is parallel to the electric field direction of the electromagnetic wave in the preset direction. In this way, the substrate layer can be polarized under the influence of an external electromagnetic field, and the electromagnetic wave forms an enhanced electric field in the direction of propagation, thereby improving the gain in that direction.
[0072] The metal wires in the first preset direction are equally spaced based on the first preset spacing; and / or, the metal wires in the second preset direction are equally spaced based on the second preset spacing. In this disclosure, the metal wires in the preset direction are equally spaced according to the set spacing, which simplifies the operation of making the metal wire array, and the resulting gain adjustment unit has a simple structure and a regular and orderly structure, ensuring the aesthetics of the structure.
[0073] In one feasible solution, all the different metal wires have the same width; and / or, all the different metal wires are made of the same material.
[0074] Of course, the width and material of each metal wire can be set separately according to actual needs to achieve flexible design.
[0075] By using the same materials and spacing for different metal wires, a consistent manufacturing process can be maintained, thereby effectively saving production costs.
[0076] In this disclosure, for the gain adjustment unit, the width range of the metal wires in the length and width directions is clearly constrained. Within this constraint range, it can be ensured that the direction of the formed electric field is parallel to the electric field direction of the electromagnetic wave in the preset direction, which can more effectively form an enhanced electric field to achieve a high gain effect on the electromagnetic wave in the set direction. In addition, constraining the width of the metal wires in the length and width directions to be the same also makes the structure regular and orderly to a certain extent, ensuring the aesthetics of the structure.
[0077] Example 3
[0078] like Figure 8 As shown, the communication system of this embodiment includes an antenna 100, a connection structure 200, and a gain adjustment device 300 as described in the above embodiment. The gain adjustment device 300 is connected to the antenna 100 through the connection structure 200.
[0079] In this solution, the flexible design of the connection structure 200 enables any type of antenna 100 to be stably and reliably connected to the gain adjustment device 300.
[0080] In a feasible solution, such as Figure 9 As shown, the connection structure 200 includes several retaining ring structures. Each retaining ring structure includes interconnected connectors and open retaining rings. The connectors are used to fit and fix the gain adjustment device 300, and the open retaining rings are used to connect to the antenna. Preferably, each connector and its corresponding retaining ring are integrally formed.
[0081] In this solution, a stable and reliable connection between the gain adjustment device and the antenna is achieved through multiple retaining ring structures. In addition, the retaining ring structure is made of soft rubber material, which allows it to be assembled and connected with antennas 100 of different shapes and sizes, enhancing the versatility of application scenarios.
[0082] In one feasible solution, the connection structure 200 is a double-sided adhesive layer, which is directly attached to the antenna 100 via the double-sided adhesive gain adjustment device 300. In this case, the antenna 100 can be a router antenna 100, etc.
[0083] In this disclosure, the double-sided adhesive layer not only achieves a stable connection between the gain adjustment device 300 and the antenna 100, but also has a simple structure, requires fewer materials, resulting in lower costs, and makes the overall structure lighter and simpler.
