Description
Technical Field
[0001] The present invention belongs to the technical field of antennas, and specifically relates to an antenna packaging structure. Background Art
[0002] In the field of wireless signal reception, flat panel antennas, as an efficient and widely used radiation unit, have been widely used in the fields of television, communication, broadcasting, satellite reception, etc. Flat panel antennas have won the favor of the market due to their simple structure, light weight, excellent radiation performance, low profile characteristics and easy installation. However, with the continuous development and popularization of wireless signal reception technology, the demand for flat panel antennas is also growing sharply. Traditional flat panel antennas usually have a large area, which makes the packaging and transportation problems of flat panel antennas increasingly prominent.
[0003] Existing flat panel antennas are made of rigid materials or slightly curved materials, resulting in large physical sizes. Especially when the antenna panel is unfolded, its area often occupies a large space. Due to the large area of the flat panel antenna, such large-sized flat panel antennas need to be packaged in a larger packaging box or packaging structure, which not only increases the consumption of packaging materials, but also makes the entire packaging structure bulky, which is not conducive to handling and storage.
[0004] In logistics transportation, large-sized packaging structures take up more transportation space, and space cost is an important expense, especially in long-distance transportation or air transportation. Large packaging volume will significantly increase transportation costs, resulting in reduced transportation efficiency and increased transportation costs. In addition, large-sized packaging structures also increase the risk of damage or deformation during transportation, further affecting the quality and performance of the antenna.
[0005] In view of the above problems, the large flat-panel antennas in the prior art are insufficient in transportation and storage, and there is an urgent need for a new antenna design that can reduce transportation and storage costs by changing its physical form. Utility Model Content
[0006] The purpose of this solution is to overcome the shortcomings and defects in the prior art and provide an antenna packaging structure that can significantly reduce the required space, thereby effectively reducing transportation costs.
[0007] This solution achieves the above-mentioned invention objectives through the following technical solutions.
[0008] The present solution provides an antenna packaging structure, including a packaging container and an antenna contained in the packaging container, the antenna including a flexible substrate, an antenna element configured on the flexible substrate, a feeder structure connected to the antenna element, and a coaxial cable connected to the feeder structure. The structure is characterized in that, in the packaging container, the flexible substrate of the antenna is wound into a cylindrical structure having a first direction and a second direction, the first direction is parallel to the axis of the cylindrical structure, and the second direction is perpendicular to the axis of the cylindrical structure, the antenna element is wound together with the flexible substrate, and can still maintain its electrical performance after unfolding, the feeder structure is located in or on one side of the cylindrical structure, and the coaxial cable is located in the cylindrical structure or between the cylindrical structure and the packaging container.
[0009] By winding the antenna into a cylindrical structure and containing it in a packaging container, the safety and stability of the antenna during transportation and storage are effectively protected, reducing the risk of damage caused by external forces or environmental factors. The design of this packaging structure further compresses the space occupied by the existing flat-panel antenna packaging structure and improves the efficiency of transportation and storage. Due to the characteristics of the flexible substrate, the antenna can be restored to its original shape and state after unfolding, ensuring the performance and use effect of the antenna. The user only needs to take the antenna out of the packaging container and unfold it, without complicated operations or adjustments. This technical solution is suitable for antennas of various sizes and shapes, and has wide applicability and flexibility.
[0010] The packaging container has an inner cavity that matches the dimensions of the first direction and the second direction, and the dimension of the packaging container in the second direction should be based on being able to accommodate the feeder structure.
[0011] By designing the inner cavity size of the packaging container, the inner cavity size is matched with the size of the first direction and the second direction after the antenna is wound, so as to achieve a close fit between the packaging and the product. The size of the packaging container in the second direction should be based on the ability to accommodate the feeder structure, ensuring that the antenna can be completely stored in the packaging container in the wound state, thereby maximizing the reduction of the packaging volume. This precise size matching not only improves the space utilization of the packaging container and reduces unnecessary waste of packaging materials, but also enhances the protective effect of the packaging on the antenna, which can effectively prevent the antenna from moving or shaking in the packaging container, ensure the stability of the antenna in the packaging container, and reduce the risk of damage caused by external impact during transportation. The packaging container can be a packaging box, a packaging bag, or other forms of packaging containers formed by blister packaging. The packaging container can be designed as a hollow prism, a prism, a pyramid or other polyhedron, or it can be designed as a hollow cylinder, a truncated cone, a cone, a sphere or other rotating body, preferably designed as a square cylinder or cylindrical structure. The square tube and cylindrical structures are more suitable for the shape of the antenna after it is rolled into a tube, and are more in line with the shape of the inner cavity. They can not only further improve the space utilization of the packaging container and reduce unnecessary waste of packaging materials, but also are easier to stack and carry, thereby improving logistics efficiency.
[0012] The size in the first direction is 3 to 15 times the size in the second direction.
[0013] By controlling the size in the first direction to be 3 to 15 times the size in the second direction, the flexible substrate is ensured to be wound as short and compact as possible. On the one hand, since the size in the first direction needs to be controlled within a certain ratio, the manufacturer will try to wind the antenna as small as possible in the first direction after winding during the packaging process; on the other hand, since the size in the second direction is much smaller than the first direction, the antenna can form a compact cylindrical structure after winding, significantly reducing its size in the second direction; both of the above aspects will significantly reduce the space occupied by the antenna in the packaging container, so that the packaging container and its inner cavity size can be designed to be smaller in both the first and second directions, which is very beneficial for saving transportation and storage space, as well as reducing packaging costs. In addition, compact rolling can also improve the impact resistance of the antenna during transportation and storage, and is more conducive to avoiding damage or deformation caused by external forces during transportation and storage, and is conducive to protecting the flexible substrate and antenna vibrator of the antenna.
[0014] The dimension in the second direction is between 1.5 and 8 cm.
[0015] By limiting the size of the second direction to within the range of 1.5 to 8 cm, the antenna has a moderate and stable size after being wound into a cylindrical structure. Such a size design will not be too large to cause the packaging container to be too large, nor will it be too small to affect the performance or structural integrity of the antenna. This moderate size design helps to achieve standardization and unification of packaging containers, which is convenient for production, transportation and management. During the winding process, the moderate size of the second direction can ensure the stability of the relative positions between the various components of the antenna, and avoid displacement or deformation caused by vibration or impact during transportation. This helps to protect the structural integrity of the antenna and ensure that it can work normally after unfolding. After the winding is completed, the moderate size of the second direction also makes the size of the packaging container moderate, which is convenient for sales, transportation and storage, and convenient for users to carry and move. For users, whether working outdoors or using indoors, it can be easily carried to meet their communication needs anytime and anywhere.
[0016] The feeder structure is located in the middle of the flexible substrate or in the middle of the edge of the flexible substrate, and the flexible substrate is divided into a left substrate and a right substrate, and the left substrate and the right substrate are respectively wound toward the feeder structure.
[0017] For antennas whose feeder structure is located in the middle of the flexible substrate or in the middle of the edge of the flexible substrate, the flexible substrate is naturally divided into a left substrate and a right substrate. By winding the left substrate and the right substrate toward the feeder structure respectively, the flexible substrate is prevented from wrapping around the feeder structure during the winding process, thereby preventing the feeder structure wrapped therein from limiting the degree of curling of the flexible substrate, so that the flexible substrate can be wound as much as possible to form a tight cylindrical structure. This design effectively reduces the overall volume of the antenna during the packaging process, so that the packaging container and its inner cavity can have a smaller size, and the packaging volume is more compact, thereby saving transportation and storage costs. While the left substrate and the right substrate are wound more tightly, a stable support structure is formed. This structure not only helps to maintain the overall shape and stability of the antenna, but also reduces structural deformation or damage caused by vibration or impact, thereby improving the stability and reliability of the antenna.
[0018] The left substrate and the right substrate are respectively wound toward the feeder structure to form two independent cylindrical structures. The feeder structure is located outside the two cylindrical structures, and the coaxial cable is located between the two cylindrical structures.
[0019] The left substrate and the right substrate both end with the feeder structure and are wound to both sides thereof, and finally form an independent cylindrical structure respectively, which is located on both sides of the feeder structure. The projection of the feeder structure on the plane where the flexible substrate is located usually has a certain width. While separating the flexible substrate into the left substrate and the right substrate, it also separates an intermediate substrate located between the left substrate and the right substrate on the flexible substrate, and the feeder structure is located on the intermediate substrate. By continuing to wind the two independent cylindrical structures onto the intermediate substrate, the feeder structure is located outside the two cylindrical structures, and at the same time, the two independent cylindrical structures are closely adjacent in space. This winding method not only makes the antenna more compact after winding, but also ensures the relative position stability between the various parts, which is beneficial to protecting the internal structure of the antenna. Placing the coaxial cable between the two cylindrical structures can make full use of the space between the two cylindrical structures, which is beneficial to reducing the space occupied by the coaxial cable, improving the compactness of the overall structure, and can also effectively prevent the coaxial cable from being impacted and squeezed by the outside during transportation, thereby protecting the internal signal transmission line from damage.
[0020] The feeder structure is located in the middle of the flexible substrate or in the middle of the edge of the flexible substrate, and separates the flexible substrate into a left substrate and a right substrate. The left substrate / right substrate is wound toward the feeder structure to form an inner cylindrical structure. The right substrate / left substrate covers the inner cylindrical structure and the feeder structure to form an outer cylindrical structure. The coaxial cable is located inside the inner cylindrical structure or between the outer cylindrical structure and the inner cylindrical structure.
[0021] The flexible substrate on one side of the feeder structure is wound toward the feeder structure to form an inner cylindrical structure, and then the flexible substrate on the other side of the feeder structure is wound and covered on the inner cylindrical structure and the outside of the feeder structure to form an outer cylindrical structure, so as to form an inner and outer double-layer cylindrical structure. The coaxial cable can be placed inside the inner cylindrical structure, or between the outer cylindrical structure and the inner cylindrical structure. In the case where the antenna vibrator is located outside the cylindrical structure relative to the flexible substrate, the coaxial cable can be inserted into the inner cylindrical structure after the inner cylindrical structure is formed, so that the internal space of the inner cylindrical structure can be fully utilized, so that the inner cylindrical structure does not need to be wound too compactly and has a smaller second direction dimension, and the antenna vibrator will not be contacted during the insertion process, so as to avoid the performance of the antenna vibrator receiving and transmitting signals being affected by mutual friction. In the case where the antenna vibrator is located inside the cylindrical structure relative to the flexible substrate, the coaxial cable can be placed on one side of the inner cylindrical structure and then wound around the flexible substrate on the other side, so as to avoid the performance of the antenna vibrator receiving and transmitting signals being affected by mutual friction. The antenna vibrator is located inside the cylindrical structure relative to the flexible substrate, which can avoid relative friction between the antenna and the inner cavity of the packaging container when the antenna is installed in the packaging container, thereby ensuring that the performance of the antenna vibrator in sending and receiving signals is not affected.
[0022] The feeder structure is located at the edge of the flexible substrate, the flexible substrate is wound from the opposite side edge of the feeder structure toward the feeder structure to form a cylindrical structure, the feeder structure is located outside the cylindrical structure, and the coaxial cable is located outside or inside the cylindrical structure.
[0023] By winding the flexible substrate from the opposite side edge of the feeder structure toward the feeder structure to form a cylindrical structure, the flexible substrate is prevented from wrapping around the feeder structure during the winding process, thereby preventing the feeder structure wrapped therein from limiting the degree of curling of the flexible substrate, so that the flexible substrate can be wound as much as possible, and the flexible substrate is easier to keep flat during the winding process, making the entire structure more compact and enhancing the stability of the overall structure. After winding, the feeder structure is located outside the cylindrical structure, and the flexible substrate at the edge of the feeder structure is not easily folded or pulled, avoiding the risk of structural damage caused by winding. In the case where the flexible substrate is wound more compactly, so that the space inside the cylindrical structure is not enough to accommodate the coaxial cable, the coaxial cable can be arranged outside the cylindrical structure, so as to avoid relative friction between the coaxial cable and the inside of the cylindrical structure, especially when the antenna vibrator is wound inside, to avoid affecting the performance of the antenna vibrator in sending and receiving signals. In the case where the flexible substrate is wound more loosely, the coaxial cable can be arranged inside the cylindrical structure to make full use of the space inside the cylindrical structure, reduce the volume of the overall structure, and save transportation and storage costs.
[0024] The feeder structure is located at the edge of the flexible substrate, and the flexible substrate is wound from the edge where the feeder structure is located toward the opposite side edge of the feeder structure to form a cylindrical structure. The feeder structure is located inside the cylindrical structure, and the coaxial cable is located outside or inside the cylindrical structure.
[0025] A cylindrical structure is formed by winding the flexible substrate from the edge where the feeder structure is located toward the edge of the opposite side of the feeder structure, so that the flexible substrate covers the feeder structure during the winding process, and the feeder structure is covered on the inner side of the cylindrical structure, so as to utilize the space inside the cylindrical structure, and at the same time, the flexible substrate does not need to be wound too compactly and also has a cylindrical structure with a smaller size in the second direction. The coaxial cable can be arranged on the outside of the cylindrical structure or on the inside of the cylindrical structure. Since the coaxial cable is connected to the feeder structure and is covered on the inside of the cylindrical structure together with the feeder structure, it will be more conducive to reducing the overall volume of the antenna packaging structure, and at the same time it can effectively avoid the adverse effects of external impact and pulling on it, reduce the damage it may suffer during the packaging process, and thus extend the service life of the coaxial cable.
[0026] The flexible substrate is a sheet structure made of thermoplastic polyurethane elastomer (TPU), polyimide (PI) or polyester (PET, etc.), the antenna vibrator is a metal conductive network layer printed on the flexible substrate, and the line width of each line in the antenna vibrator is 3 to 12 mm.
[0027] Thermoplastic polyurethane elastomer (TPU), polyimide (PI) or polyester (PET, etc.) is used as the material of the flexible substrate, giving the antenna excellent flexibility and crease resistance. This material is not only lightweight, but also can maintain its structural integrity when subjected to external forces and is not easily damaged. This allows the antenna to maintain its original functionality and stability in scenarios where bending and winding are required. Designing the antenna vibrator as a metal conductive network layer printed on a flexible substrate not only simplifies the antenna manufacturing process and reduces production costs, but also improves the antenna integration, the accuracy and reliability of the antenna vibrator, and also enhances the bonding between the antenna vibrator and the flexible substrate to avoid the risk of damage caused by winding. At the same time, the metal conductive network layer has excellent conductive properties, ensuring the efficiency and stability of the antenna vibrator during signal transmission. The line width of each line in the antenna vibrator is set to 3 to 12 mm. The selection of this range fully considers the balance between antenna performance and manufacturing difficulty. A wider line width is conducive to reducing resistance and improving the radiation efficiency of the antenna; at the same time, this line width range is also within the capabilities of existing manufacturing technology, and can achieve high manufacturing accuracy and consistency.
[0028] Compared with the prior art, this solution has the following beneficial effects: by winding the antenna into a cylindrical structure and placing it in a packaging container, this solution effectively protects the safety and stability of the antenna during transportation and storage, reduces the risk of damage caused by external forces or environmental factors, compresses the space occupied by the antenna packaging structure, and improves the efficiency of transportation and storage.

[0039] In order to enable those skilled in the art to better understand the present solution, the present solution is further described in detail below in conjunction with specific embodiments.
[0040] Figure 1 1 shows a possible packaging structure of the antenna 200, which includes a packaging container 100 and the antenna 200 contained in the packaging container 100. Figures 2-3 As shown, the antenna 200 includes a flexible substrate 210 , an antenna element 220 disposed on the flexible substrate 210 , a feeder structure 230 connected to the antenna element 220 , and a coaxial cable 240 connected to the feeder structure 230 .
[0041] like Figure 1 As shown, in the packaging container 100, the flexible substrate 210 of the antenna 200 is wound into a cylindrical structure having a first direction and a second direction, wherein the first direction is parallel to the axis of the cylindrical structure, and the second direction is perpendicular to the axis of the cylindrical structure. It should be noted that the cylindrical structure formed by winding is similar to a hollow cylindrical structure or a flattened hollow cylindrical structure, wherein the axis is equivalent to the axis of the hollow cylindrical structure, the first direction is equivalent to the axial direction of the hollow cylindrical structure, and the second direction is equivalent to the radial direction of the hollow cylindrical structure. The antenna vibrator 220 is wound together with the flexible substrate 210, and can still maintain its electrical performance after unfolding. Figures 4 to 7 As shown, the feeder structure 230 is located inside the cylindrical structure or on one side of the cylindrical structure, and the coaxial cable 240 is located inside the cylindrical structure or between the cylindrical structure and the packaging container 100 .
[0042] The antenna 200 is wound into a cylindrical structure and contained in the packaging container 100, which effectively protects the safety and stability of the antenna 200 during transportation and storage, and reduces the risk of damage caused by external forces or environmental factors. The design of this packaging structure further compresses the occupied space relative to the packaging structure of the existing flat antenna 200, and improves the efficiency of transportation and storage. Due to the characteristics of the flexible substrate 210, the antenna 200 can be restored to its original shape and state after unfolding, ensuring the performance and use effect of the antenna 200. The user only needs to take the antenna 200 out of the packaging container 100 and unfold it, without complicated operations or adjustments. This technical solution is applicable to antennas 200 of various sizes and shapes, and has wide applicability and flexibility.
[0043] The packaging container 100 may be a packaging box, a packaging bag, or other packaging containers formed by blister packaging. The packaging container may be designed as a hollow prism, prism, pyramid or other polyhedron, or a hollow cylinder, truncated cone, cone, sphere or other rotating body, preferably a square cylindrical structure (such as Figure 1 ) or cylindrical structures (such as Figure 8 ). By designing the packaging container 100 to be a square tube or a cylindrical structure, it is more suitable for the shape of the antenna 200 after being wound into a tube. This design not only improves the space utilization of the packaging container 100 and reduces unnecessary waste of packaging materials, but also facilitates stacking and transportation, thereby improving logistics efficiency.
[0044] Whether it is a square tube or a cylinder, or other shapes, the packaging container 100 has an inner cavity that matches the dimensions of the first direction and the second direction, so as to achieve a close fit between the packaging and the product. The dimensions of the second direction of the packaging container 100 should be based on the ability to accommodate the feeder structure 230, ensuring that the antenna 200 can be completely stored in the packaging container 100 in the wound state, thereby minimizing the packaging volume. This precise size matching not only further improves the space utilization of the packaging container 100 and reduces unnecessary waste of packaging materials, but also strengthens the protective effect of the packaging on the antenna 200, which can effectively prevent the antenna 200 from moving or shaking in the packaging container 100, ensure the stability of the antenna 200 in the packaging container 100, and reduce the risk of damage caused by external impact during transportation.
[0045] The size of the cylindrical structure can be controlled within the range of 3 to 15 times the size in the first direction of the second direction, ensuring that the flexible substrate 210 is wound as short and compact as possible. On the one hand, since the size in the first direction needs to be controlled within a certain ratio, the manufacturer will try to wind the first direction as small as possible during the packaging process; on the other hand, since the size in the second direction is much smaller than the first direction, the antenna 200 can form a compact cylindrical structure after winding, significantly reducing its size in the second direction; both of the above aspects will significantly reduce the space occupied by the antenna 200 in the packaging container 100, so that the packaging container 100 and its inner cavity size can be designed to be smaller in both the first and second directions, which is very beneficial for saving transportation and storage space and reducing packaging costs. In addition, rolling compactly can also improve the impact resistance of the antenna 200 during transportation and storage, and is more conducive to avoiding damage or deformation caused by external forces during transportation and storage, and is conducive to protecting the flexible substrate 210 and antenna vibrator 220 of the antenna 200.
[0046] The size of the second direction can be controlled between 1.5 and 8 cm, so that the antenna 200 has a moderate and stable size after being wound into a cylindrical structure. Such a size design will not be too large to cause the packaging container 100 to be too large, nor will it be too small to affect the performance or structural integrity of the antenna 200. This moderate size design helps to achieve the standardization and unification of the packaging container 100, which is convenient for production, transportation and management. During the winding process, the moderate size of the second direction can ensure the relative position between the components of the antenna 200 is stable, and avoid displacement or deformation caused by vibration or impact during transportation. This helps to protect the structural integrity of the antenna 200 and ensure that it can work normally after unfolding. After the winding is completed, the moderate size of the second direction also makes the size of the packaging container 100 moderate, which is convenient for sales, transportation and storage, and convenient for users to carry and move. For users, whether working outdoors or using indoors, it can be easily carried to meet their communication needs anytime and anywhere.
[0047] The feed line structure 230 may be disposed in the middle of the flexible substrate 210, such as Figure 2 , can also be configured at the edge of the flexible substrate 210, specifically the middle of the edge, such as Figure 3 Regardless of whether it is configured in the middle of the flexible substrate 210 or in the middle of the edge, the flexible substrate 210 will be naturally divided into a left substrate and a right substrate. Figure 4As shown, the left substrate and the right substrate can be respectively wound toward the feeder structure 230 to prevent the flexible substrate 210 from wrapping around the feeder structure 230 during the winding process, thereby preventing the feeder structure 230 wrapped therein from limiting the degree of curling of the flexible substrate 210, so that the flexible substrate 210 can be wound as much as possible to form a tight cylindrical structure. This design effectively reduces the overall volume of the antenna 200 during the packaging process, so that the packaging container 100 and its inner cavity can have a smaller size, and the packaging volume is more compact, thereby saving transportation and storage costs. While the left substrate and the right substrate are wound more tightly, a stable support structure is formed. This structure not only helps to maintain the overall shape and stability of the antenna 200, but also reduces structural deformation or damage caused by vibration or impact, thereby improving the stability and reliability of the antenna 200.
[0048] The left substrate and the right substrate both end with the feeder structure 230, and are respectively wound to both sides thereof, and finally each forms an independent cylindrical structure, which is located on both sides of the feeder structure 230. The projection of the feeder structure 230 on the plane where the flexible substrate 210 is located usually has a certain width. While separating the flexible substrate 210 into the left substrate and the right substrate, it also separates an intermediate substrate between the left substrate and the right substrate on the flexible substrate 210, and the feeder structure 230 is located on the intermediate substrate. The two independent cylindrical structures can continue to be wound onto the intermediate substrate, so that the feeder structure 230 is located outside the two cylindrical structures, and at the same time, the two independent cylindrical structures are closely adjacent in space. This winding method not only makes the antenna 200 more compact after winding, but also ensures that the relative positions between the various parts are stable, which is conducive to protecting the internal structure of the antenna 200. Placing the coaxial cable 240 between the two cylindrical structures can make full use of the space between the two cylindrical structures, which is beneficial to reducing the space occupied by the coaxial cable 240 and improving the compactness of the overall structure. It can also effectively prevent the coaxial cable 240 from being subjected to external impact and extrusion during transportation, thereby protecting the internal signal transmission line from damage.
[0049] In addition to being wound toward the feeder structure 230, the flexible substrate 210 may also be wound in such a manner that the left substrate / right substrate is wound toward the feeder structure 230 to form an inner cylindrical structure, and the remaining right substrate / left substrate covers the inner cylindrical structure and the feeder structure 230 to form an outer cylindrical structure, forming an inner and outer double-layer cylindrical structure, such as Figure 5. The coaxial cable 240 can be placed inside the inner cylindrical structure or between the outer cylindrical structure and the inner cylindrical structure. In the case where the antenna vibrator 220 is located outside the cylindrical structure relative to the flexible substrate 210, the coaxial cable 240 can be inserted into the inner cylindrical structure after the inner cylindrical structure is formed. This can fully utilize the internal space of the inner cylindrical structure, so that the inner cylindrical structure does not need to be wound too compactly and has a smaller second direction dimension, and will not contact the antenna vibrator 220 during the insertion process, thereby avoiding mutual friction that affects the performance of the antenna vibrator 220 in transmitting and receiving signals. In the case where the antenna vibrator 220 is located inside the cylindrical structure relative to the flexible substrate 210, the coaxial cable 240 can be placed on one side of the inner cylindrical structure and then wound around the flexible substrate 210 on the other side, which can also avoid mutual friction that affects the performance of the antenna vibrator 220 in transmitting and receiving signals. The antenna vibrator 220 is located inside the cylindrical structure relative to the flexible substrate 210, which can avoid relative friction between it and the inner cavity of the packaging container 100 when the antenna 200 is installed in the packaging container 100, ensuring that the performance of the antenna vibrator 220 in sending and receiving signals is not affected.
[0050] In the case where the feeder structure 230 is disposed at the edge of the flexible substrate 210, the flexible substrate 210 may also be wound from the opposite side edge of the feeder structure 230 toward the feeder structure 230 to form a cylindrical structure, such as Figure 6 , to prevent the flexible substrate 210 from wrapping around the feeder structure 230 during the winding process, and then to prevent the feeder structure 230 wrapped therein from limiting the degree of curling of the flexible substrate 210, so that the flexible substrate 210 can be wound as much as possible, and the flexible substrate 210 is easier to keep flat during the winding process, making the entire structure more compact and enhancing the stability of the overall structure. After winding, the feeder structure 230 is located outside the cylindrical structure, and the flexible substrate 210 at the edge of the feeder structure 230 is not easily folded or pulled, avoiding the risk of structural damage caused by winding. In the case where the flexible substrate 210 is wound more compactly, so that the space inside the cylindrical structure is not enough to accommodate the coaxial cable 240, the coaxial cable 240 can be arranged outside the cylindrical structure, so as to avoid relative friction between the coaxial cable 240 and the inside of the cylindrical structure, especially when the antenna vibrator 220 is wound inside, to avoid affecting the performance of the antenna vibrator 220 in transmitting and receiving signals. In the case where the flexible substrate 210 is wound loosely, the coaxial cable 240 can be arranged inside the cylindrical structure to fully utilize the space inside the cylindrical structure, reduce the volume of the overall structure, and save transportation and storage costs.
[0051] In the case where the feeder structure 230 is disposed at the edge of the flexible substrate 210, the flexible substrate 210 may also be wound from the edge where the feeder structure 230 is located toward the edge of the opposite side of the feeder structure 230 to form a cylindrical structure, such as Figure 7, so that the flexible substrate 210 forms a coating on the feeder structure 230 during the winding process, and the feeder structure 230 is coated on the inner side of the cylindrical structure, so as to utilize the space inside the cylindrical structure, and at the same time, the flexible substrate 210 does not need to be wound too compactly and also has a cylindrical structure with a smaller size in the second direction. The coaxial cable 240 can be arranged on the outside of the cylindrical structure, or it can be arranged on the inside of the cylindrical structure. Since the coaxial cable 240 is connected to the feeder structure 230, it is coated on the inside of the cylindrical structure together with the feeder structure 230, which will be more conducive to reducing the overall volume of the antenna 200 packaging structure, and at the same time, it can effectively avoid the adverse effects of external impact and pulling on it, reduce the damage it may suffer during the packaging process, and thus extend the service life of the coaxial cable 240.
[0052] The flexible substrate 210 may be a sheet structure made of thermoplastic polyurethane elastomer (TPU), polyimide (PI) or polyester (PET, etc.). Thermoplastic polyurethane elastomer (TPU), polyimide (PI) or polyester (PET, etc.) as the material of the flexible substrate 210 can give the antenna 200 excellent flexibility and crease resistance. This material is not only lightweight, but also able to maintain its structural integrity when subjected to external forces and is not easily damaged. This allows the antenna 200 to maintain its original functionality and stability in scenarios where bending and winding are required.
[0053] The antenna vibrator 220 can be a metal conductive network layer printed on the flexible substrate 210, which not only simplifies the manufacturing process of the antenna 200 and reduces the production cost, but also improves the integration of the antenna 200, the accuracy and reliability of the antenna vibrator 220, and also enhances the bonding force between the antenna vibrator 220 and the flexible substrate 210, avoiding the risk of damage caused by winding. At the same time, the metal conductive network layer has excellent conductive properties, ensuring the efficiency and stability of the antenna vibrator 220 during signal transmission.
[0054] The line width of each line in the antenna element 220 can be set to 3 to 12 mm, and the selection of this range fully considers the balance between the performance and manufacturing difficulty of the antenna 200. A wider line width is conducive to reducing resistance and improving the radiation efficiency of the antenna 200; at the same time, this line width range is also within the capabilities of existing manufacturing technology, and can achieve higher manufacturing accuracy and consistency.
