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 present solution aims to overcome at least one defect in the prior art and provide an antenna packaging structure that can significantly reduce the required space, thereby effectively reducing transportation costs.
[0007] In order to solve the above technical problems, the following technical solutions are adopted:
[0008] This solution provides an antenna packaging structure, including a packaging container and an antenna contained in the packaging container, wherein the antenna includes a flexible substrate, an antenna vibrator configured on the flexible substrate, a feeder structure connected to the antenna vibrator, and a coaxial cable connected to the feeder structure. The structure is characterized in that: in the packaging container, the flexible substrate is in a folded state, and its folding line avoids the feeder structure, and each fold leaves an elastic space with a water droplet-shaped cross section between the flexible substrates on both sides of the folding line, and the water droplet-shaped refers to a shape with one end round and the other end gradually becoming pointed; the antenna vibrator is folded together with the flexible substrate, and can still maintain its electrical performance after unfolding; the coaxial cable is located in the elastic space or between the flexible substrate and the packaging container.
[0009] By folding the antenna and placing 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. An elastic space with a water droplet-shaped cross-section is left between the flexible substrates on both sides of the folding line to prevent the antenna vibrator folded with the flexible substrate from being over-folded, ensuring that its electrical performance is not affected. The design of this packaging structure further compresses the space occupied compared to the packaging structure of the existing flat antenna, 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 size of the cavity of the packaging container matches the size of the flexible substrate after being folded.
[0011] By designing the cavity size of the packaging container, the cavity size is matched with the size of the antenna after folding, so that the packaging and the product are closely fitted. This design not only ensures that the antenna can be completely stored in the packaging container in the folded state, but also improves the space utilization rate of the packaging container, reduces unnecessary waste of packaging materials, and minimizes the packaging volume. This precise size matching can effectively prevent the antenna from moving or shaking in the packaging container, while ensuring the stability of the antenna in the packaging container, enhancing the protective effect of the packaging on the antenna, and reducing 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 polyhedrons, or it can be designed as a hollow cylinder, a truncated cone, a cone, a sphere, or other rotating bodies. Among them, prisms and cylinders are more adapted to the shape of the antenna after folding, and are more in line with the shape of the cavity, which can not only further improve the space utilization rate of the packaging container, reduce unnecessary waste of packaging materials, but also make it easier to stack and carry, which is conducive to improving logistics efficiency.
[0012] The flexible substrate has a first direction and a second direction perpendicular to each other. It is folded more than twice in the first direction to form a long strip structure. The two side edges of the long strip structure parallel to the second direction are respectively close to the two side edges of the feeder structure.
[0013] By folding the flexible substrate multiple times in the first direction, the antenna that originally occupied a large space is effectively compressed into a long strip structure, thereby greatly reducing the volume required for packaging, so that the packaging container and its inner cavity can have a smaller size, and the volume of the entire antenna packaging structure is more compact. This not only reduces transportation costs, but also improves the utilization efficiency of storage space, especially in scenarios where space is limited. This advantage is particularly obvious. By making the two side edges of the long strip structure parallel to the second direction close to the two side edges of the feeder structure, the compactness of the folding of the flexible substrate is maximized to form a stable structure, which 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. The folded long strip structure can be packaged in a long strip packaging container, so that the antenna presents a neat and orderly appearance after packaging, which improves the overall texture of the product.
[0014] The feeder structure is located in the middle of the flexible substrate in the first direction, and the flexible substrate is divided into a left substrate and a right substrate. The left substrate is folded to the right along the edge of the feeder structure, and the right substrate and the left substrate covered thereon continue to be folded to the right several times along the edge of the feeder structure to form the long strip structure. Alternatively, the feeder structure is located in the middle of the flexible substrate in the first direction, and the flexible substrate is divided into a left substrate and a right substrate. The right substrate is folded to the left along the edge of the feeder structure, and the left substrate and the right substrate covered thereon continue to be folded to the left several times along the edge of the feeder structure to form the long strip structure.
[0015] For an antenna whose feeder structure is located in the middle of the flexible substrate in the first direction, its flexible substrate is naturally divided into a left substrate and a right substrate. By folding the flexible substrate on one side of the feeder structure toward the other side along the edge of the feeder structure, and then continuing to fold it several times in the first direction along the edge of the feeder structure until it can no longer be folded, a long strip structure with two side edges close to the two side edges of the feeder structure is formed. This orderly folding method not only ensures that the size of the long strip structure formed by folding will not fluctuate greatly and can be completely accommodated in the packaging container, but also helps to standardize the packaging process and improve packaging efficiency. Among them, after the flexible substrate on one side of the feeder structure is folded toward the other side along the edge of the feeder structure, the process of continuing to fold it several times in the first direction is carried out in a purse-shaped folding manner, so as to make full use of the elastic space left by each folding, which can further improve the compactness of the flexible substrate folding, and avoid the elastic space from being excessively squeezed by external force, thereby avoiding the electrical performance of the antenna vibrator from being affected. The coaxial cable can be arranged between the long strip structure and the packaging container, or in the elastic space. The latter can make full use of the elastic space and prop up the elastic space to prevent the elastic space from being overly squeezed by external forces, thereby preventing the electrical performance of the antenna vibrator from being affected. Specifically, it can be configured in the elastic space formed by the first folding or in the elastic space formed by the second folding.
[0016] The feeder structure is located in the middle of the flexible substrate in the first direction, and the flexible substrate is divided into a left substrate and a right substrate. The left substrate is folded to the right along the edge of one side of the feeder structure, and the right substrate is folded to the left several times together with the left substrate covered thereon, and finally folded along the edge of the other side of the feeder structure to form the long strip structure. Alternatively, the feeder structure is located in the middle of the flexible substrate in the first direction, and the flexible substrate is divided into a left substrate and a right substrate. The right substrate is folded to the left along the edge of one side of the feeder structure, and the left substrate is folded to the right several times together with the right substrate covered thereon, and finally folded along the edge of the other side of the feeder structure to form the long strip structure.
[0017] First, fold the flexible substrate on one side of the feeder structure toward the other side along the edge of the feeder structure, and fold the flexible substrate on the other side of the feeder structure toward the feeder structure several times in the aforementioned folded state until it cannot be folded any further, and the last folding is performed along the edge of the other side of the feeder structure. This folding method can ensure that the two side edges of the final long strip structure are close to the two side edges of the feeder structure, respectively, and ensure that the long strip structure can be completely accommodated in the packaging container. In addition to the first and last foldings that need to be performed along the edge of the feeder structure, the position of the folding line in the intermediate process can be adjusted according to actual conditions, so as to maximize the compactness of the final long strip structure, and the folding method is more flexible. The coaxial cable can be arranged between the long strip structure and the packaging container, or in the elastic space. The latter can make full use of the elastic space and prop up the elastic space to prevent the elastic space from being excessively squeezed by external forces, thereby preventing the electrical performance of the antenna vibrator from being affected. It is best to be arranged in the elastic space formed by the last fold.
[0018] The size of the long strip structure in the second direction is 3 to 15 times of its size in the first direction, and the size of the long strip structure in the first direction is 1.5 to 8 cm.
[0019] By controlling the size of the long strip structure in the second direction to be 3 to 15 times its size in the first direction, the flexible substrate is ensured to be folded as short and compact as possible. On the one hand, since the size in the second direction needs to be controlled within a certain ratio range, the manufacturer will determine the first direction and the second direction as much as possible during the packaging process, in a way that is conducive to making the size in the second direction smaller after folding; on the other hand, since the size in the first direction is much smaller than the second direction, the antenna can form a compact long strip structure after folding, significantly reducing its size in the first 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 folding 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.
[0020] By limiting the size in the first direction to within the range of 1.5 to 8 cm, the antenna has a moderate and stable size after being folded into a long strip structure. Such a size design is neither too large to cause the packaging container to be too large, nor 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 folding process, the moderate size in the first 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 folding, the moderate size in the first 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.
[0021] The flexible substrate has a first direction and a second direction perpendicular to each other, and is folded several times in the first direction and then folded several times in the second direction to form a wallet-like structure.
[0022] By folding in two mutually perpendicular directions, the antenna can be compressed into a more compact form, significantly reducing the volume it occupies in the package, which is conducive to reducing the size of the packaging container and its inner cavity, making the entire antenna packaging structure more compact and lightweight. This not only reduces the packaging cost, but also makes transportation and storage more convenient, and is particularly suitable for scenes with limited space. During the folding process, whether it is folding in the first direction or folding in the second direction, if it is folded more than twice in this direction, it is preferably folded in a purse folding manner, so that the elastic space formed by each fold can be fully utilized, making the folded antenna more compact. After folding, the antenna as a whole presents a structure similar to a folding wallet, and can be packaged in a flat packaging container, so that the antenna presents a neat and orderly appearance after packaging, which improves the overall texture of the product. The coaxial cable can be configured between the wallet-like structure and the packaging container, or it can be configured in the elastic space. The latter can make full use of the elastic space and prop up the elastic space to prevent the elastic space from being excessively squeezed by external forces, thereby preventing the electrical performance of the antenna vibrator from being affected. Specifically, it can be configured in the elastic space formed by folding in the second direction.
[0023] The feed line structure is located in the middle of the flexible substrate in the first direction, and the flexible substrate is folded an even number of times in the first direction. And / or, the feed line structure is located in the middle of the flexible substrate in the second direction, and the flexible substrate is folded an even number of times in the second direction.
[0024] By folding an even number of times in the first direction and / or the second direction, the folding lines are evenly distributed on both sides of the feeder structure, which helps the folding lines avoid the feeder structure, avoids the need to repeatedly adjust the position of the folding lines during the folding process, and improves the folding efficiency. An even number of foldings also ensures that the flexible substrate can form a symmetrical structure after folding, making the antenna more neat and orderly in appearance. At the same time, this folding method also effectively reduces the space occupied by the antenna in the package and improves space utilization.
[0025] The wallet-like structure has a third direction perpendicular to the first direction and the second direction, a size in the third direction is 2-6 cm, and a size in the first direction and / or the second direction is 5-15 cm.
[0026] By limiting the dimensions in three mutually perpendicular directions within a specific range, the antenna has a moderate and stable size after being folded into a wallet-like structure. Such a size design is neither too large to cause the packaging container to be too bulky, nor 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 folding process, the moderate size of the third direction can ensure that the elastic space is not overly squeezed, which helps to protect the structural integrity of the antenna and ensure that it can work normally after unfolding. After folding, the moderate size of the third 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.
[0027] 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 3~12mm.
[0028] 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 able to 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 is 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's 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 folding. 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 3~12mm, and 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.
[0029] Compared with the prior art, this solution has the following beneficial effects: By folding the antenna 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. An elastic space with a water droplet-shaped cross section is left between the flexible substrates on both sides of the folding line to prevent the antenna vibrator folded with the flexible substrate from being over-folded, ensuring that its electrical performance is not affected.

[0040] 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.
[0041] Figure 1~2 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. Figure 3~4 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 .
[0042] like Figure 1~2 As shown, in the packaging container 100, the flexible substrate 210 is in a folded state, and its folding line avoids the feeder structure 230. Each folding leaves an elastic space 201 with a water droplet-shaped cross section between the flexible substrate 210 on both sides of the folding line. The water droplet shape refers to a shape with one end round and the other end gradually becoming pointed, such as Figures 5 to 9 ; The antenna element 220 is folded together with the flexible substrate 210 and can still maintain its electrical performance after unfolding; the coaxial cable 240 is located in the elastic space 201 or between the flexible substrate 210 and the packaging container 100.
[0043] After the antenna 200 is folded, it is 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. An elastic space 201 with a water droplet-shaped cross section is left between the flexible substrates 210 on both sides of the folding line to prevent the antenna vibrator 220 folded together with the flexible substrate 210 from being over-folded, ensuring that its electrical performance is not affected. The design of this packaging structure further compresses the space occupied compared 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.
[0044] The packaging container 100 may be a packaging box, a packaging bag, or other packaging containers formed by blister packaging. The structure may be designed as a hollow prism (such as Figure 1~2 ), prisms, pyramids and other polyhedrons, and can also be designed as hollow cylinders (such as Fig.10 ), truncated cones, cones, spheres and other rotating bodies. By designing the packaging container 100 as a hollow prism or cylinder, it is easy to stack and carry, thereby improving logistics efficiency. Moreover, the prism and cylinder are more suitable for the shape of the antenna 200 after folding, and are more in line with the shape of the cavity, which can further improve the space utilization of the packaging container 100 and reduce unnecessary waste of packaging materials. Regardless of the structure, the cavity size of the packaging container 100 matches the size of the flexible substrate 210 after folding, so as to achieve a close fit between the packaging and the product. This design not only ensures that the antenna 200 can be completely stored in the packaging container 100 in the folded state, but also improves the space utilization of the packaging container 100, reduces unnecessary waste of packaging materials, and minimizes the packaging volume. This precise size matching can effectively prevent the antenna 200 from moving or shaking in the packaging container 100, while ensuring the stability of the antenna 200 in the packaging container 100, enhancing the protective effect of the packaging on the antenna 200, and reducing the risk of damage caused by external impact during transportation.
[0045] In the first direction and the second direction perpendicular to each other, the flexible substrate 210 can be folded more than twice in the first direction. Figures 5 to 8, so that the antenna 200, which originally occupied a large space, is effectively compressed into a long strip structure, thereby greatly reducing the volume required for packaging, so that the packaging container 100 and its inner cavity can have a smaller size, and the volume of the entire antenna 200 packaging structure is more compact. This not only reduces transportation costs, but also improves the utilization efficiency of storage space, especially in scenarios with limited space, this advantage is particularly obvious. The two side edges of the long strip structure parallel to the second direction can be close to the two side edges of the feeder structure 230 respectively, maximizing the compactness of the folding of the flexible substrate 210, forming a stable structure, which 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, and improves the stability and reliability of the antenna 200. After folding, a long strip packaging container 100 can be used for packaging, so that the antenna 200 presents a neat and orderly appearance after packaging, which improves the overall texture of the product.
[0046] like Figure 3~4 As shown, assuming that the first direction is the left-right direction, in this direction, the feed line structure 230 can be configured in the middle of the flexible substrate 210, and the flexible substrate 210 is naturally divided into a left substrate and a right substrate. Figures 5 and 6 As shown, the process of folding into the above-mentioned long strip structure can be: the left (right) side substrate is folded to the right (left) along the edge of the feeder structure 230, and the right (left) side substrate together with the left (right) side substrate covering it continues to be folded to the right (left) several times along the edge of the feeder structure 230. This orderly folding method not only ensures that the size of the long strip structure formed by folding will not fluctuate greatly, and can be completely accommodated in the packaging container 100, but also helps to standardize the packaging process and improve packaging efficiency. Among them, after the first folding, continuing to fold to the right (left) several times means that the process is carried out in a purse folding manner, so as to make full use of the elastic space 201 left by each folding, which can further improve the compactness of the folding of the flexible substrate 210, and can prevent the elastic space 201 from being excessively squeezed by external force, thereby preventing the electrical performance of the antenna vibrator 220 from being affected. It should be noted that the number of folding in the purse folding manner here is not limited to three times, but can also be more times. The coaxial cable 240 can be arranged between the long strip structure and the packaging container 100, or in the elastic space 201. The latter can make full use of the elastic space 201 and prop up the elastic space 201 to prevent the elastic space 201 from being excessively squeezed by external forces, thereby preventing the electrical performance of the antenna vibrator 220 from being affected. Specifically, it can be arranged in the elastic space 201 formed by the first folding, or in the elastic space 201 formed by the second folding.
[0047] like Figure 7-8As shown, the process of folding into the above-mentioned long strip structure can also be: the left (right) side substrate is folded to the right (left) along the edge of one side of the feeder structure 230, and the right (left) side substrate together with the left (right) side substrate covering it is folded to the left (right) several times, and the last time is folded along the edge of the other side of the feeder structure 230. This folding method can ensure that the two side edges of the final long strip structure are close to the two side edges of the feeder structure 230, respectively, and ensure that the long strip structure can be completely accommodated in the packaging container 100. In addition to the first and last foldings that need to be performed along the edge of the feeder structure 230, the position of the folding line in the intermediate process can be adjusted according to actual conditions, so as to maximize the compactness of the final long strip structure, and the folding method is more flexible. The coaxial cable 240 can be arranged between the long strip structure and the packaging container 100, or it can be arranged in the elastic space 201. The latter can make full use of the elastic space 201 and prop up the elastic space 201 to prevent the elastic space 201 from being excessively squeezed by external forces, thereby preventing the electrical performance of the antenna vibrator 220 from being affected. It is best to be arranged in the elastic space 201 formed by the last folding.
[0048] The size of the strip-shaped structure in the second direction can be 3 to 15 times the size in the first direction, ensuring that the flexible substrate 210 is folded as short and compact as possible. On the one hand, since the size in the second direction needs to be controlled within a certain ratio range, the manufacturer will determine the first direction and the second direction as much as possible during the packaging process, in a way that is conducive to making the size in the second direction smaller after folding; on the other hand, since the size in the first direction is much smaller than the second direction, the antenna 200 can form a compact strip-shaped structure after folding, significantly reducing its size in the first 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 direction and the second direction, which is very beneficial for saving transportation and storage space, and reducing packaging costs. In addition, compact folding 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.
[0049] The size of the long strip structure in the first direction can be in the range of 1.5~8cm, so that the antenna 200 has a moderate and stable size after being folded into the long strip 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 folding process, the moderate size in the first 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 folding is completed, the moderate size in the first 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.
[0050] like Figure 3~4 As shown, in the first direction and the second direction perpendicular to each other, the flexible substrate 210 can be folded several times in the first direction and then folded several times in the second direction, such as Fig. 9 , so that the antenna 200 can be compressed into a more compact form, significantly reducing the volume it occupies in the package, which is conducive to reducing the size of the packaging container 100 and its inner cavity, making the entire antenna 200 packaging structure more compact and lightweight. This not only reduces the packaging cost, but also makes transportation and storage more convenient, and is particularly suitable for scenes with limited space. During the folding process, whether it is folding in the first direction or folding in the second direction, if folding in this direction more than twice, it is preferably folded in a purse folding manner, so that the elastic space 201 formed by each folding can be fully utilized, so that the folded antenna 200 is more compact. After folding, the antenna 200 as a whole presents a structure similar to a folding wallet such as a two-fold or three-fold, referred to as a wallet-like structure, which can be packaged with a flat packaging container 100, so that the antenna 200 presents a neat and orderly appearance after packaging, which improves the overall texture of the product. The coaxial cable 240 can be configured between the wallet-like structure and the packaging container 100, or it can be configured in the elastic space 201. The latter can make full use of the elastic space 201 and prop up the elastic space 201 to prevent the elastic space 201 from being overly squeezed by external force, thereby preventing the electrical performance of the antenna element 220 from being affected. Specifically, it can be configured in the elastic space 201 formed by folding in the second direction.
[0051] The feed line structure 230 may be disposed in the middle of the flexible substrate 210 in the first direction. Figure 4, can also be configured in the middle of the second direction of the flexible substrate 210, can also be configured in the middle of the first direction and the second direction of the flexible substrate 210, such as Figure 3 .like Fig. 9 As shown, in the process of folding into the above-mentioned wallet-like structure, it can be folded an even number of times in the corresponding direction, so that the folding lines are evenly distributed on both sides of the feeder structure 230, which is conducive to the folding lines avoiding the feeder structure 230, avoiding the need to repeatedly adjust the position of the folding lines during the folding process, and improving the folding efficiency. The even number of foldings also ensures that the flexible substrate 210 can form a symmetrical structure after folding, making the antenna 200 more neat and orderly in appearance. At the same time, this folding method also effectively reduces the space occupied by the antenna 200 in the package, improving space utilization.
[0052] In the third direction perpendicular to the first direction and the second direction, the size of the wallet-like structure can be set to 2~6cm, and its size in the first direction and / or the second direction can be set to 5~15cm, so that the antenna 200 has a moderate and stable size after being folded into the wallet-like 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 folding process, the moderate size of the third direction can ensure that the elastic space 201 is not over-extruded, which helps to protect the structural integrity of the antenna 200 and ensure that it can work normally after unfolding. After the folding is completed, the moderate size of the third 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.
[0053] 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 light, but also can 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 is required.
[0054] 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 folding. 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.
[0055] The line width of each line in the antenna element 220 can be set to 3-12 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.
