Description

Technical Field

[0001] The utility model relates to an antenna structure, in particular to an adjustable antenna. Background Art

[0002] In wireless transmission, the environmental medium near the antenna directly affects the quality of communication. In actual use, the environmental medium near the antenna, especially the metal conductor, will change the impedance of the antenna, causing the antenna impedance to deviate in frequency, seriously affecting the antenna's transceiver performance, because the impedance mismatch may cause signal transmission loss or distortion; the metal conductor has an absorption effect on the signal. When the antenna radiates electromagnetic waves out of the antenna or receives electromagnetic waves into the antenna, the metal conductor may absorb part of the energy in the air, reducing the energy conversion efficiency of the entire communication system, thereby affecting the communication effect; the metal conductor will shield the antenna's signal. Since electromagnetic waves cannot penetrate metal conductors, metal conductors will reflect part of the electromagnetic waves to other directions. When the metal conductor is very large relative to the antenna, this shielding effect is particularly obvious, which will directly affect the signal reception and transmission in the direction of the antenna.

[0003] At present, in order to enhance the strength of navigation marks, metal materials are usually used. The antenna on the navigation mark will inevitably come into contact with the metal conductor or be too close to it. If a linear antenna is used, the antenna will come into contact with the metal conductor, seriously affecting the communication signal. Utility Model Content

[0004] The utility model aims to provide an adjustable antenna, and the technical problem to be solved is to reduce the interference of metal conductors on antenna communication.

[0005] The utility model is realized by the following technical solutions:

[0006] An adjustable antenna comprises a plurality of antenna segments, wherein adjacent antenna segments are connected via a connecting component; the connecting component is used to adjust the angle between adjacent antenna segments;

[0007] The outer surface of the connecting assembly is provided with a first electromagnetic shielding layer;

[0008] The connecting assembly comprises a locking portion and two connecting portions;

[0009] A locking hole is provided at one end of the connecting portion, and the locking portion is used to lock the two connecting portions after passing through the locking holes of the two connecting portions;

[0010] The other end of the connecting portion is connected to the antenna segment.

[0011] By adjusting the angle between adjacent antenna segments through the above-mentioned connecting assembly, the antenna can be flexibly adjusted according to different communication requirements and environmental conditions. The setting of the above-mentioned locking portion allows the two connecting parts to be firmly connected together, thereby ensuring that the angle between the antenna segments is stable and reliable. By passing the locking portion through the locking holes of the two connecting parts and locking them, the angle between the antenna segments can be adjusted, so that the antenna can be flexibly adjusted according to specific communication requirements and environmental conditions to optimize the radiation pattern and directivity, thereby avoiding or reducing sensitivity to interference sources such as metal conductors. When the antenna is adjusted to a suitable angle, it may be able to better penetrate or avoid the electromagnetic field around the metal conductor, reducing signal attenuation and distortion.

[0012] The electromagnetic shielding layer is arranged on the outer surface of the above-mentioned connection component, which can effectively isolate and reduce the interference of the external electromagnetic field on the antenna communication. The electromagnetic shielding layer is usually made of conductive materials, which can absorb, reflect or disperse electromagnetic waves from interference sources such as metal conductors, thereby protecting the antenna from these interferences; this shielding effect can improve the stability and reliability of the antenna signal, especially in the case of dense metal conductors or complex electromagnetic environment.

[0013] In summary, the adjustable antenna has a significant beneficial effect in reducing the interference of metal conductors on antenna communication through angle adjustment and the design of electromagnetic shielding layer; this design not only improves the communication quality and stability, but also enhances the adaptability and flexibility of the antenna, enabling it to maintain efficient communication performance in various complex environments.

[0014] Furthermore, the above-mentioned connecting part includes a fixing head and a connecting head;

[0015] One end of the fixing head is provided with a plurality of claws, which enclose a clamping hole, and the axis of the clamping hole is parallel to or coincides with the axis of the fixing head;

[0016] The locking hole is arranged at the other end of the fixing head, and the axis of the locking hole is perpendicular to the axis of the fixing head;

[0017] The outer side wall of the above-mentioned claw is provided with a thread;

[0018] The connector is provided with a threaded hole, which is adapted to the thread on the outer wall of the claw;

[0019] When connecting the adjacent antenna segments, the ends of the antenna segments extend through the threaded holes into the clamping holes, and the connector is rotated so that the claws retract inwards.

[0020] The design of the fixing head allows it to firmly clamp the end of the antenna segment. By rotating the connector, the claws will contract inwards, thereby tightly clamping the antenna segment, which not only ensures a firm connection between the antenna segment and the connector, but also adapts to antenna segments of different sizes and shapes by adjusting the degree of contraction of the claws, increasing the versatility and flexibility of the antenna.

[0021] The threaded connection between the fixing head and the connector enhances the stability and reliability of the connection; this connection method can withstand large tension and torque, ensuring that the antenna can maintain stable performance under various environmental conditions. Since the end of the antenna segment is tightly clamped in the clamping hole, the signal leakage and attenuation caused by loose connection is reduced, which helps to improve the overall signal transmission efficiency of the antenna and reduce the impact of interference sources such as metal conductors on communication quality.

[0022] In summary, through the above-mentioned fixed head and connecting head and the interaction mechanism between them, the stability and reliability of the antenna structure are enhanced, thereby improving the communication quality and stability, so that it can better adapt to various complex communication environments.

[0023] Furthermore, along the axis of the connecting head, away from the fixing head, the diameter of the threaded hole on the connecting head gradually decreases.

[0024] As the threaded hole diameter gradually decreases, the claws are gradually subjected to greater compression force when the connector is rotated, thereby clamping the antenna segment more tightly. This tight clamping effect not only reduces signal loss caused by loose connections, but also improves the stability of the entire antenna structure, making it more resistant to interference from the external environment.

[0025] The gradually decreasing threaded hole diameter also helps improve the accuracy and reliability of the connection. During the rotation of the connector, the change in the hole diameter makes it easier to sense the contact and clamping state between the claws and the antenna segment, thereby ensuring the correctness and firmness of the connection. This design reduces the risk of communication failure and performance degradation caused by improper connection;

[0026] Since the connection between the above-mentioned connector and the antenna segment is tighter, it is more difficult for the external electromagnetic field to penetrate into the antenna, thereby reducing the impact of interference sources such as metal conductors on antenna communication, helping to improve the antenna's anti-interference ability and ensure the stability and reliability of communication.

[0027] Furthermore, the locking portion includes a locking rod, an abutment block and a holding rod, and the locking rod passes through the locking hole;

[0028] One end of the locking rod is connected to the abutment block, and the other end of the locking rod is provided with a connecting rod, the axis of the connecting rod is perpendicular to the axis of the locking rod;

[0029] One end of the holding rod extends to a side away from the connecting portion to form a protrusion;

[0030] The protrusion is provided with a connecting hole, the connecting hole is sleeved on the connecting rod, and the holding rod rotates around the connecting rod.

[0031] The design of the locking rod passing through the locking hole allows the two connecting parts to be firmly locked together. By adjusting the position of the locking rod, the angle between the antenna segments can be adjusted and locked, which not only enhances the stability of the antenna structure, but also improves the stability and reliability of the antenna communication.

[0032] The arrangement of the abutment block further enhances the locking effect. When the locking rod is tightened, the abutment block will tightly abut against the outer surface of the connection part, preventing the connection part from loosening or shifting under the action of external force, helping to maintain the stability of the angle between the antenna segments and reduce signal loss and communication quality degradation caused by loose connection parts.

[0033] The design of the gripping rod provides a more convenient operation mode for the user. The user can conveniently adjust the position and locking force of the locking rod by gripping and rotating the gripping rod. The setting of the protrusion and the connecting hole enables the gripping rod to rotate around the connecting rod, and this rotation mechanism makes the operation more flexible and convenient.

[0034] The protrusion formed by the gripping rod extending away from the connecting portion also allows the user to more clearly perceive the change in the locking state. By observing the position and state of the protrusion, the user can determine whether the locking is in place, thereby ensuring that the connection between the antenna segments is stable and reliable.

[0035] Furthermore, the locking portion further comprises an elastic member, which is sleeved on the locking rod, and two ends of the elastic member respectively abut against the abutting block and the connecting portion.

[0036] The addition of the elastic member can provide a more stable and uniform locking force. When the locking rod is tightened, the elastic member will be compressed and generate a reaction force, which can be evenly distributed between the abutment block and the connecting part. When the locking rod is released, the reaction force drives the abutment block to drive the locking rod to reset.

[0037] Furthermore, a clamping block is provided on the outer side wall of the connecting portion, and a distance is left between the clamping block and the outer side wall of the connecting portion, and the distance is greater than the thickness of the gripping rod;

[0038] The holding rod is clamped in the interval.

[0039] By arranging a clamping block on the outer side wall of the connecting portion and leaving a distance between the clamping block and the outer side wall of the connecting portion to accommodate the holding rod, the structural stability and operational convenience of the adjustable antenna are enhanced.

[0040] The spacing design between the above-mentioned snap-in block and the outer side wall of the connecting part allows the holding rod to be easily snapped into it; this snap-in mechanism not only simplifies the installation process, but also ensures a firm connection between the holding rod and the connecting part; the user can conveniently operate the locking part through the holding rod to adjust the angle between the antenna segments.

[0041] The clamping block provides support and fixing points for the gripping rod, thereby avoiding the problem of locking failure caused by loosening of the gripping rod.

[0042] Furthermore, one end of the clamping block is connected to the connecting portion; and the other end of the clamping block is provided with an inclined surface.

[0043] When looking from the end of the clamping block to the middle of the clamping block, the inclined surface is inclined downward, and the inclined surface is used to guide the holding rod to enter the clamping interval more conveniently.

[0044] Furthermore, a second electromagnetic shielding layer is provided on the outer surface of the antenna segment.

[0045] A second electromagnetic shielding layer is provided on the outer surface of the antenna segment, which provides additional protection for reducing the interference of metal conductors on antenna communication. This design further reduces the interference of external electromagnetic waves on the antenna by electromagnetically shielding the antenna segment at the periphery.

[0046] The second electromagnetic shielding layer can effectively isolate and reduce the interference of external electromagnetic fields on antenna communication. By wrapping the antenna segment in the electromagnetic shielding layer, a relatively closed electromagnetic environment can be formed to prevent external electromagnetic signals from penetrating into the antenna, thereby protecting the antenna from interference sources such as metal conductors.

[0047] The second electromagnetic shielding layer can also improve the signal transmission efficiency and communication quality of the antenna. Due to the presence of the electromagnetic shielding layer, the antenna can better focus and transmit signals, reduce signal loss and attenuation during transmission, help maintain the stability and continuity of communication, and improve the communication performance of the antenna.

[0048] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0049] By adjusting the angle between adjacent antenna segments through the above-mentioned connection components, the antenna can be flexibly adjusted according to different communication requirements and environmental conditions. This adjustment can optimize the radiation pattern and directivity of the antenna, thereby more effectively avoiding or reducing sensitivity to interference sources such as metal conductors. When the antenna is adjusted to the appropriate angle, it may be able to better penetrate or avoid the electromagnetic field around the metal conductor, reducing signal attenuation and distortion.

[0050] The electromagnetic shielding layer is arranged on the outer surface of the above-mentioned connection component, which can effectively isolate and reduce the interference of the external electromagnetic field on the antenna communication. The electromagnetic shielding layer is usually made of conductive materials, which can absorb, reflect or disperse electromagnetic waves from interference sources such as metal conductors, thereby protecting the antenna from these interferences; this shielding effect can improve the stability and reliability of the antenna signal, especially in the case of dense metal conductors or complex electromagnetic environment.

[0051] In summary, the adjustable antenna has a significant beneficial effect in reducing the interference of metal conductors on antenna communication through angle adjustment and the design of electromagnetic shielding layer; this design not only improves the communication quality and stability, but also enhances the adaptability and flexibility of the antenna, enabling it to maintain efficient communication performance in various complex environments.

[0060] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0061] Example 1

[0062] Combination Figure 1 , this embodiment 1 provides an adjustable antenna, including a plurality of antenna segments 10, wherein adjacent antenna segments 10 are connected via a connecting component 20; the connecting component 20 is used to adjust the angle between adjacent antenna segments 10;

[0063] The outer surface of the connecting component 20 is provided with a first electromagnetic shielding layer, and the electromagnetic shielding layer can be made of one or more of steel, iron, copper, aluminum, carbon ink material and absorbing material.

[0064] By adjusting the angle between adjacent antenna segments 10 through the connection assembly 20, the antenna can be flexibly adjusted according to different communication requirements and environmental conditions. This adjustment can optimize the radiation pattern and directivity of the antenna, thereby more effectively avoiding or reducing sensitivity to interference sources such as metal conductors. When the antenna is adjusted to a suitable angle, it may be able to better penetrate or avoid the electromagnetic field around the metal conductor, reducing signal attenuation and distortion.

[0065] The first electromagnetic shielding layer is arranged on the outer surface of the above-mentioned connecting component 20, which can effectively isolate and reduce the interference of the external electromagnetic field on the antenna communication. The first electromagnetic shielding layer is usually made of conductive material, which can absorb, reflect or disperse electromagnetic waves from interference sources such as metal conductors, thereby protecting the antenna from these interferences; this shielding effect can improve the stability and reliability of the antenna signal, especially when the metal conductors are dense or the electromagnetic environment is complex.

[0066] By optimizing the antenna angle and adding an electromagnetic shielding layer, the adjustable antenna can significantly reduce signal loss during transmission. Metal conductors usually cause reflection, scattering and absorption of antenna signals, thereby reducing communication quality. The design of the adjustable antenna can minimize these negative effects and ensure that the signal can be transmitted more stably and clearly.

[0067] The design of the adjustable antenna makes it highly adaptable and flexible. In different communication scenarios and environments, the location and distribution of metal conductors may vary; by adjusting the angle of the antenna and utilizing the electromagnetic shielding layer, this antenna can better adapt to these changes, ensuring high communication performance in various situations.

[0068] In summary, the adjustable antenna has a significant beneficial effect in reducing the interference of metal conductors on antenna communication through angle adjustment and the design of electromagnetic shielding layer; this design not only improves the communication quality and stability, but also enhances the adaptability and flexibility of the antenna, enabling it to maintain efficient communication performance in various complex environments.

[0069] Example 2

[0070] Based on Example 1, Figure 2 and Figure 3 , the connecting assembly 20 comprises a locking portion 22 and two connecting portions 21;

[0071] A locking hole 26 is provided at one end of the connecting portion 21, and the locking portion 22 is used to lock the two connecting portions 21 after passing through the locking holes 26 of the two connecting portions 21;

[0072] The other end of the connecting portion 21 is connected to the antenna segment 10 .

[0073] The arrangement of the locking portion 22 enables the two connecting portions 21 to be firmly connected together, thereby ensuring that the angle between the antenna segments 10 is stable and reliable. By passing the locking portion 22 through the locking holes 26 of the two connecting portions 21 and locking them, the angle between the antenna segments 10 can be adjusted, so that the antenna can be flexibly adjusted according to specific communication requirements and environmental conditions to optimize the radiation pattern and directivity, thereby avoiding or reducing sensitivity to interference sources such as metal conductors.

[0074] Example 3

[0075] Based on Example 2, Figure 3 , the connecting portion 21 includes a fixing head 23 and a connecting head 24;

[0076] A plurality of claws 27 are disposed at one end of the fixing head 23, and the claws 27 enclose a clamping hole 28, wherein the axis of the clamping hole 28 is parallel to or coincides with the axis of the fixing head 23;

[0077] The locking hole 26 is disposed at the other end of the fixing head 23, and the axis of the locking hole 26 is perpendicular to the axis of the fixing head 23;

[0078] The outer side wall of the above-mentioned claw 27 is provided with a thread;

[0079] The connector 24 is provided with a threaded hole 29, which is adapted to the thread on the outer wall of the claw 27;

[0080] When connecting the adjacent antenna segments 10 , the end of the antenna segment 10 extends through the threaded hole 29 into the clamping hole 28 , and the connector 24 is rotated so that the claws 27 are retracted inwardly.

[0081] The design of the fixing head 23 allows it to firmly clamp the end of the antenna segment 10. By rotating the connecting head 24, the claws 27 will shrink inward, thereby tightly clamping the antenna segment 10, which not only ensures a firm connection between the antenna segment 10 and the connecting portion 21, but also can adapt to antenna segments 10 of different sizes and shapes by adjusting the degree of shrinkage of the claws 27, thereby increasing the versatility and flexibility of the antenna.

[0082] The threaded connection between the fixing head 23 and the connector 24 enhances the stability and reliability of the connection; this connection method can withstand greater tension and torque, ensuring that the antenna can maintain stable performance under various environmental conditions. Since the end of the antenna segment 10 is tightly clamped in the clamping hole 28, signal leakage and attenuation caused by loose connection are reduced, which helps to improve the overall signal transmission efficiency of the antenna and reduce the impact of interference sources such as metal conductors on communication quality.

[0083] In summary, through the above-mentioned fixing head 23 and connecting head 24 and the interaction mechanism between them, the stability and reliability of the antenna structure are enhanced, thereby improving the communication quality and stability, so that it can better adapt to various complex communication environments.

[0084] Example 4

[0085] Based on Example 3, Figure 3 Along the axis of the connecting head 24 and away from the fixing head 23 , the diameter of the threaded hole 29 on the connecting head 24 gradually decreases.

[0086] Since the diameter of the threaded hole 29 gradually decreases, when the connector 24 is rotated, the claws 27 will gradually be subjected to a greater compression force, thereby more tightly clamping the antenna segment 10. This tight clamping effect not only reduces the signal loss caused by loose connection, but also improves the stability of the entire antenna structure, making it more resistant to interference from the external environment.

[0087] The gradually decreasing diameter of the threaded hole 29 also helps to improve the accuracy and reliability of the connection. During the rotation of the connector 24, the change in the diameter makes it easier to sense the contact and clamping state between the claw 27 and the antenna segment 10, thereby ensuring the correctness and firmness of the connection. This design reduces the risk of communication failure and performance degradation caused by improper connection;

[0088] Since the connection between the connector 24 and the antenna segment 10 is tighter, it is more difficult for the external electromagnetic field to penetrate into the antenna, thereby reducing the impact of interference sources such as metal conductors on antenna communication, helping to improve the antenna's anti-interference capability and ensure communication stability and reliability.

[0089] Example 5

[0090] Based on any one of Embodiments 2 to 4, Figure 4 The locking portion 22 includes a locking rod 222, an abutment block 223 and a holding rod 221, and the locking rod 222 passes through the locking hole 26;

[0091] One end of the locking rod 222 is connected to the abutment block 223, and the other end of the locking rod 222 is provided with a connecting rod 224, the axis of the connecting rod 224 is perpendicular to the axis of the locking rod 222;

[0092] One end of the holding rod 221 extends away from the connecting portion 21 to form a protrusion;

[0093] The protrusion is provided with a connecting hole, and the connecting hole is sleeved on the connecting rod 224 , and the holding rod 221 rotates around the connecting rod 224 .

[0094] The locking steps of the above-mentioned locking rod 222 are: one end of the holding rod 221 without a protrusion approaches the connecting part 21 until it abuts against the surface of the connecting part 21. At this time, the end of the holding rod 221 with a protrusion gradually moves away from the connecting part 21, so that the abutting block 223 approaches the connecting part 21, and the locking rod 222 is gradually tightened, completing the locking operation of the locking rod 222.

[0095] The steps for loosening the locking rod 222 are as follows: the end of the holding rod 221 without the protrusion gradually moves away from the connecting part 21, and the end of the holding rod 221 with the protrusion approaches the connecting part 21, so that the abutment block 223 gradually moves away from the connecting part 21, and the locking rod 222 is gradually loosened. After the locking rod 222 is loosened, the angle of the two connecting parts 21 can be adjusted.

[0096] The design of the locking rod 222 passing through the locking hole 26 allows the two connecting parts 21 to be firmly locked together. By adjusting the position of the locking rod 222, the angle between the antenna segments 10 can be adjusted and locked, which not only enhances the stability of the antenna structure, but also improves the stability and reliability of the antenna communication.

[0097] The arrangement of the abutment block 223 further enhances the locking effect. When the locking rod 222 is tightened, the abutment block 223 will tightly abut against the outer surface of the connection part 21, preventing the connection part 21 from loosening or displacement under the action of external force, helping to maintain the stability of the angle between the antenna segments 10 and reduce signal loss and communication quality degradation caused by loose connection part 21.

[0098] The design of the gripping rod 221 provides a more convenient operation mode for the user. The user can conveniently adjust the position and locking force of the locking rod 222 by gripping and rotating the gripping rod 221. The arrangement of the protrusion and the connecting hole enables the gripping rod 221 to rotate around the connecting rod 224, and this rotation mechanism makes the operation more flexible and convenient.

[0099] The protrusion formed by the holding rod 221 extending away from the connecting portion 21 also allows the user to more clearly perceive the change of the locking state. By observing the position and state of the protrusion, the user can determine whether the locking is in place, thereby ensuring that the connection between the antenna segments 10 is stable and reliable.

[0100] Example 6

[0101] Based on Example 5, Figure 2 and Figure 4 The locking portion 22 further includes an elastic member 225, which may be a spring, a spring sheet, etc. The elastic member 225 is sleeved on the locking rod 222, and the two ends of the elastic member 225 respectively abut against the abutment block 223 and the connecting portion 21; when the locking rod 222 is tightened, the elastic member 225 is in a compressed state; when the locking rod 222 is released, the elastic member 225 is in a natural state.

[0102] The addition of the elastic member 225 can provide a more stable and uniform locking force. When the locking rod 222 is tightened, the elastic member 225 will be compressed and generate a reaction force, which can be evenly distributed between the abutment block 223 and the connecting portion 21. When the locking rod 222 is released, the reaction force drives the abutment block 223 to drive the locking rod 222 to reset.

[0103] The elastic member 225 also helps to absorb and buffer external vibrations and shocks. In a complex communication environment, the antenna may be subject to vibrations and shocks from various directions; by introducing the elastic member 225, these vibrations and shocks can be effectively absorbed, reducing their impact on the antenna structure and communication performance. This design helps to maintain the stability and continuity of antenna communication and reduce the risk of communication interruption or quality degradation due to external interference.

[0104] In addition, the use of the elastic member 225 can also improve the convenience and comfort of operation. By adjusting the tightness of the elastic member 225, the user can flexibly adjust the size of the locking force as needed. This design makes the operation simpler and more intuitive, and improves the user's experience.

[0105] Example 7

[0106] On the basis of Example 5 or Example 6, Figure 2The outer wall of the connecting portion 21 is provided with a clamping block 25, and a distance is left between the clamping block 25 and the outer wall of the connecting portion 21, and the distance is greater than the thickness of the gripping rod 221;

[0107] The holding rod 221 is clamped in the interval. The specific operation method is: hold one end of the holding rod 221 without the protrusion and move it closer to the connecting part 21. When it abuts against the surface of the connecting part 21, rotate the holding rod 221 to drive the locking rod 222 to rotate, and then clamp the holding rod 221 into the interval.

[0108] By arranging the clamping block 25 on the outer side wall of the connecting portion 21 and leaving a space between the clamping block 25 and the outer side wall of the connecting portion 21 to accommodate the holding rod 221 , the structural stability and operational convenience of the adjustable antenna are enhanced.

[0109] The spacing design between the above-mentioned snap-in block 25 and the outer wall of the connecting part 21 allows the holding rod 221 to be easily snapped into it; this snap-in mechanism not only simplifies the installation process, but also ensures a firm connection between the holding rod 221 and the connecting part 21; the user can conveniently operate the locking part 22 through the holding rod 221, thereby adjusting the angle between the antenna segments 10.

[0110] The clamping block 25 provides a support and fixing point for the holding rod 221 , thereby preventing the locking failure problem caused by the loosening of the holding rod 221 .

[0111] Specific embodiments, combined with Figure 5 One end of the clamping block 25 is connected to the connecting portion 21 ; the other end of the clamping block 25 is provided with an inclined surface.

[0112] When looking from the end of the clamping block 25 to the middle of the clamping block 25 , the inclined surface is inclined downward, and the inclined surface is used to guide the holding rod 221 to enter the clamping interval more conveniently.

[0113] Example 8

[0114] Based on any of the above embodiments, the outer surface of the antenna segment 10 is covered with a second electromagnetic shielding layer; in order to reduce the negative impact of the electromagnetic shielding layer on antenna signal reception, an electromagnetic shielding material with lower conductivity and dielectric constant can be selected.

[0115] The second electromagnetic shielding layer is provided on the outer surface of the antenna segment 10, which provides additional protection for reducing the interference of the metal conductor on the antenna communication. This design further reduces the interference of external electromagnetic waves on the antenna by electromagnetically shielding the antenna segment 10 at the periphery.

[0116] The second electromagnetic shielding layer can effectively isolate and reduce the interference of external electromagnetic fields on antenna communication. By wrapping the antenna segment 10 in the electromagnetic shielding layer, a relatively closed electromagnetic environment can be formed to prevent external electromagnetic signals from penetrating into the antenna, thereby protecting the antenna from interference sources such as metal conductors.

[0117] The second electromagnetic shielding layer can also improve the signal transmission efficiency and communication quality of the antenna. Due to the presence of the electromagnetic shielding layer, the antenna can better focus and transmit signals, reduce signal loss and attenuation during transmission, help maintain the stability and continuity of communication, and improve the communication performance of the antenna.

[0118] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
