[0032] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0033] First, a brief description of the relevant content involved in this invention will be given.

[0034] Existing 4G products, such as 4G PTZ cameras, are cost-effective network cameras (Internet Protocol Cameras, IPCs). Furthermore, due to production line constraints and cable lifespan limitations, their 4G boards cannot be placed in the upper cavity and must be placed inside the PTZ. Therefore, these 4G PTZ cameras employ an extra-long RF cable and a routing scheme where the RF cable is shared with other cables. However, this extra-long RF cable and routing scheme results in poor overall wireless performance.

[0035] To improve wireless performance, there are currently three common solutions in the industry: one is to use a large-size antenna, the second is to use a separate RF cable, and the third is to use a low-loss cable.

[0036] However, while using large-size antennas can improve wireless performance, they are expensive and their appearance is inconsistent with the overall device. Using separate RF cables can improve RF performance, but it places high demands on the overall device structure and has limited performance improvement. Using low-loss cables, although using readily available materials, is expensive and also has limited performance improvement.

[0037] To address the aforementioned issues, this invention provides an antenna performance enhancement method, an antenna, and a network camera. While improving wireless performance, it also shortens debugging time, reduces overall costs, and ensures the aesthetic appeal of the entire device.

[0038] The following is combined with Figures 1-13The present invention describes an antenna performance enhancement method, an antenna, and a network camera.

[0039] Figure 1 This is a flowchart illustrating the antenna performance enhancement method provided by the present invention, as shown below. Figure 1 As shown, it includes the following: Step 101: Increase the number of radio frequency lines in the antenna so that the antenna contains at least two radio frequency lines.

[0040] Specifically, this antenna is also an antenna device that can be applied to network cameras to enable data transmission.

[0041] Specifically, radio frequency (RF) lines, also known as RF feeders, are the core carriers for signal transmission.

[0042] In practical applications, most antennas use only one radio frequency (RF) line, which can easily lead to performance bottlenecks such as high signal loss and insufficient transmission stability. To enhance antenna performance, the number of RF lines can be increased to initially improve antenna performance, such as transmission performance, thus providing hardware support for stable data transmission from network cameras.

[0043] Step 102: Perform a ground area increase process on the at least two radio frequency lines to enhance the performance of the antenna, the ground area increase process comprising intertwining the at least two radio frequency lines.

[0044] In practical applications, at least two RF lines can be used for signal boosting to further improve transmission and radio frequency performance. This embodiment of the invention intertwines at least two RF lines, thereby increasing the ground area, effectively reducing grounding impedance, and significantly enhancing the antenna's transmission and radio frequency performance.

[0045] The antenna performance enhancement method provided by this invention utilizes at least two radio frequency lines to improve the performance of the wireless antenna. Compared to the traditional approach of increasing antenna size, this method shortens antenna debugging time, reduces overall equipment manufacturing costs, and maintains the aesthetic appeal of the device, avoiding the negative impact of a large antenna on the device's design. Furthermore, this invention improves overall device performance without altering the overall structure of the antenna-using product, thus enhancing performance while ensuring the device's waterproofing and cruise control capabilities.

[0046] Optionally, after increasing the ground area of ​​the at least two radio frequency lines, the method further includes: The at least two radio frequency lines are wrapped with shielding material.

[0047] Specifically, shielding material is also a wrapping material.

[0048] In practical applications, shielding material can be used to wrap at least two intertwined radio frequency (RF) wires to optimize antenna performance. By encapsulating the intertwined RF wires with shielding material, the ground area of ​​the antenna can be increased, thereby improving antenna performance.

[0049] In this embodiment of the invention, by using at least two radio frequency (RF) lines and shielding material, after winding the at least two RF lines to increase the ground area, the shielding material is used to wrap the at least two RF lines that are wound together, thereby improving the signal transmission stability and anti-interference capability and improving the wireless performance of the antenna.

[0050] In some embodiments, the shielding material may be conductive adhesive tape and / or a set material, wherein the shielding performance of the set material is superior to that of the conductive adhesive tape.

[0051] In practical applications, the better the shielding performance of the shielding material, the better. Therefore, shielding materials with superior shielding performance can be used, such as conductive adhesive tape and / or a shielding material whose shielding performance is superior to that of the conductive adhesive tape, thereby improving antenna performance and RF linearity, and ensuring the integrity and stability of signal transmission.

[0052] It should be noted that this solution does not limit the selection of shielding materials, which can be selected according to the actual application scenario of the equipment (such as interference intensity, cost budget, and installation space).

[0053] Optionally, wrapping the at least two radio frequency lines with shielding material includes: The shielding material is used to wrap at least the connection points between the at least two radio frequency lines and the antenna body in the antenna.

[0054] Specifically, the antenna includes an antenna body and at least two intertwined radio frequency (RF) wires, one of which is connected to the antenna body, while the other RF wires are not connected to the antenna body. The antenna body includes an antenna body housing and a printed circuit board (PCB) housed inside the housing. The RF wires are electrically connected to the antenna body, specifically through RF interfaces on the PCB inside the antenna body, ensuring the stability and reliability of signal transmission. The shielding material covers at least the connection points of the intertwined RF wires to the antenna body, corresponding to the signal transmission start points of those RF wires.

[0055] In practical applications, see Figure 2 , Figure 2This is a schematic diagram illustrating a scenario where the shielding material provided by this invention is applied. The optimal location for starting the shielding material application is at the beginning of at least two radio frequency (RF) lines, specifically at the connection point where the two intertwined RF lines connect to the antenna body. From the perspective of RF signal transmission characteristics, this connection point is the initial node where the RF signal is fed from the antenna body PCB board to the RF lines. It belongs to the critical area with the highest RF signal radiation intensity and the strongest sensitivity to electromagnetic interference. Therefore, applying shielding material at this location can achieve optimal shielding gain. Thus, starting the shielding material application at the beginning of at least two RF lines can improve radiation performance to a certain extent.

[0056] Optionally, wrapping the at least two radio frequency lines with shielding material includes: The shielding material is used to wrap the at least two radio frequency lines for at least a predetermined length, the predetermined length being the product of a first predetermined value and the wavelength of the frequency band in which the antenna operates.

[0057] Specifically, the wrapping length of the shielding material is greater than or equal to a set length; the first set value can be greater than or equal to 1 / 4, for example, the first set value can be 1 / 4 or 1 / 3, etc.

[0058] In practical applications, the optimal length of the shielding material should be sufficient to cover the entire path of the radio frequency cable (at least two intertwined radio frequency cables).

[0059] To reduce costs, or considering scenarios where the product interior cannot be fully enclosed, a partial enclosed approach can be used. Based on the formulas for frequency, wavelength, and wave velocity, and empirical verification, the minimum effective enclosed length of the shielding material is at least 1 / 4 of the wavelength corresponding to the antenna's operating frequency band. The relevant calculation formulas are as follows: fλ0=c λ=λ0 / (ε γ μ γ ) 1 / 2 Where f is the operating frequency of the antenna signal, c is the speed of light, λ0 is the wavelength in free space, λ is the wavelength of the PCB board, i.e., the wavelength of the antenna's operating frequency band, and ε γ Let μ be the relative permittivity of the PCB board. γ The relative permeability of the PCB board.

[0060] For example, when the starting frequency of the antenna's operating band is 824 MHz and a PCB board is installed in the antenna, the calculated 1 / 4 wavelength corresponding to the operating band is approximately 45.5 mm. In this case, a shielding material with a wrapping length of 55 mm is selected, which is greater than 45.5 mm, ensuring the effectiveness of the shielding solution.

[0061] In this embodiment of the invention, by setting the wrapping length to be greater than or equal to a set length, and the set length being the product of a first set value and the wavelength of the frequency band in which the antenna operates, it is possible to avoid completely wrapping the radio frequency line while ensuring antenna performance and radio frequency performance, thereby reducing the amount of shielding material used and thus reducing costs.

[0062] Optionally, the radio frequency line includes a first type of line, or the radio frequency line includes a first type of line and at least one second type of line, wherein the second type of line is an adapter line.

[0063] In practical applications, each RF line contains at least one Class 1 line.

[0064] Specifically, the first type of cable includes an RF1.13 coaxial cable and a miniature coaxial connector mounted at one end of the RF1.13 coaxial cable. The other end of the first type of cable is used to connect to the antenna body, such as by soldering it to a PCB board in the antenna body, or by fixing it to a PCB board in the antenna body through other connection structures.

[0065] Furthermore, depending on the specific needs of the scenario, such as length requirements or rotation requirements, at least one Category 2 cable, i.e., an adapter cable, can be added to the Category 1 cable. Adjacent cables need to be connected using an adapter, thus connecting the Category 1 cable and at least one Category 2 cable in series to form an RF cable. The number of adapter cables included in the RF cable can be adjusted based on the internal installation space requirements of wireless communication devices such as network cameras.

[0066] Specifically, the adapter cable includes the RF1.13 coaxial cable and two miniature coaxial connectors installed at both ends of the RF1.13 coaxial cable.

[0067] The miniature coaxial connector is used to achieve precise docking between the first type of wire and the adapter wire, and between the adapter wire and the adapter.

[0068] Specifically, the miniature coaxial connector is an Integrated Panel Mount External (IPEX) connector, which is designed specifically for wireless communication devices. The IPEX connector can be a first-generation IPEX connector, or other IPEX series connectors with equivalent signal transmission performance.

[0069] For example, see Figure 3 , Figure 3This is a schematic diagram of the adapter cable provided by the present invention. The adapter cable uses a light gray Teflon RF1.13 coaxial cable (RF1.13 line) as the main signal transmission component. Teflon material possesses excellent high-temperature resistance, aging resistance, insulation, and low dielectric loss characteristics, effectively reducing the attenuation of radio frequency signals during transmission and ensuring the purity and stability of signal transmission. Simultaneously, the small diameter of the RF1.13 coaxial cable allows it to fit into the narrow wiring space of embedded devices, improving installation flexibility. A first-generation IPEX connector is installed at each end of the RF1.13 coaxial cable. This connector is a miniaturized radio frequency connection device with advantages such as convenient insertion and removal, stable connection, and high impedance matching, avoiding signal reflection and crosstalk problems caused by poor connection. Furthermore, the adapter cable length can be 490±5 mm, adapting to the internal installation space requirements of most wireless communication devices such as network cameras.

[0070] Optionally, see Figure 4 , Figure 4 This is a schematic diagram of the cross-sectional structure of the RF1.13 coaxial cable provided by the present invention: the cross-sectional structure of the RF1.13 coaxial cable consists of a jacket, an outer conductor, an insulator, and an inner conductor, from the outside to the inside.

[0071] Specifically, the shielding performance of the RF cable itself directly affects the overall signal transmission quality of the antenna; the better the shielding performance of the RF cable, the better. The shielding performance of the RF cable mainly depends on the outer conductor of the RF1.13 coaxial cable. Therefore, in this solution, the outer conductor of the RF1.13 coaxial cable can be made of metals, ceramics, plastics, or polymers with good shielding performance. By configuring the RF cable with materials that have excellent shielding performance, combined with external shielding material wrapping, a dual shielding protection is formed, consisting of its own material shielding and external wrapping shielding, which together improves the antenna performance.

[0072] Optionally, the type of the antenna is a monopole antenna or a designated antenna, wherein the designated antenna is an antenna other than a monopole antenna that improves performance based on antenna ground area.

[0073] It should be noted that monopole antennas possess the technical characteristics of simple structure, miniaturized size, and easy integration, making them directly adaptable to the installation requirements of embedded wireless communication devices such as network cameras. Furthermore, within a certain range, antenna performance is positively correlated with ground area; that is, within a certain range, the larger the ground area of ​​the monopole antenna, the better its performance. Increasing the ground area can effectively reduce the antenna's input VSWR and improve signal transmission stability. The specified antenna can also achieve significant performance optimization by expanding its ground area.

[0074] A monopole antenna consists of a vertical conductor and a conductive ground plane. For example... Figure 5 As shown, Figure 5 This is a schematic diagram of a scenario using the monopole antenna provided by the present invention: the green area represents the base plate, that is, the base plate of the PCB board inside the antenna; the yellow line on the base plate is the monopole antenna with a length of λ / 4; the yellow area represents the conductive ground plane, such as a metal ground; where λ is the dielectric wavelength, that is, the wavelength of the antenna's operating frequency band.

[0075] The ground plane can be an artificial grounding grid or a physical conductor board, i.e., a PCB ground plane. As a mirror conductor of a monopole, the size of the ground plane directly affects the integrity of the mirrored current. Ideally, an infinitely large ground plane can perfectly simulate the lower half of a symmetrical dipole, making the radiation pattern consistent with the upper half of the dipole. In practical applications, the radius of the ground plane needs to be at least one wavelength to approximate the effect of an infinitely large plane; otherwise, the mirrored current will be distorted due to edge effects. When the radius of the ground plane increases from 1 / 4 wavelength (λ) to 1 wavelength, the radiation efficiency improves significantly; however, the improvement slows down beyond one wavelength.

[0076] The antenna performance enhancement method provided by this invention utilizes two radio frequency lines and shielding material to improve the performance of the wireless antenna. Compared to the traditional approach of increasing antenna size, this method shortens antenna debugging time, reduces overall equipment manufacturing costs, and maintains the aesthetic appeal of the device, avoiding the negative impact of a large antenna on the device's design. Furthermore, this invention improves overall device performance without altering the overall structure of the antenna-using product, thus enhancing performance while ensuring the device's waterproofing and cruise control capabilities.

[0077] The antenna provided by the present invention is described below. The antenna described below and the antenna performance enhancement method described above can be referred to in correspondence.

[0078] Figure 6 This is a schematic diagram of the antenna structure provided by the present invention, as shown below. Figure 6 As shown, the antenna includes: The antenna body 601 and at least two intertwined radio frequency lines 602.

[0079] The antenna body 601 includes an antenna body shell and a PCB board placed inside the antenna body shell.

[0080] The antenna provided by this invention utilizes at least two radio frequency lines to improve wireless antenna performance. Compared to the traditional approach of increasing antenna size, this shortens antenna debugging time, reduces overall equipment manufacturing costs, and maintains the aesthetic appeal of the device, avoiding the negative impact of a large antenna on the device's design. Furthermore, this invention improves overall device performance without altering the device's structural integrity, achieving performance enhancement while ensuring waterproofing and cruise control capabilities.

[0081] Optionally, the at least two radio frequency lines are wrapped with shielding material. The shielding material covers at least the connection points between the at least two radio frequency lines and the antenna body; The shielding material has a wrapping length greater than or equal to a set length, which is the product of a first set value and the wavelength of the frequency band in which the antenna operates.

[0082] Optionally, the radio frequency line includes a first type of line, or the radio frequency line includes a first type of line and at least one second type of line, wherein the second type of line is an adapter line; The first type of cable includes an RF1.13 coaxial cable and a miniature coaxial connector mounted at one end of the RF1.13 coaxial cable; The adapter cable includes the RF1.13 coaxial cable and two miniature coaxial connectors installed at both ends of the RF1.13 coaxial cable; The insulating layer material of the RF1.13 coaxial cable is light gray Teflon; The RF1.13 coaxial cable consists of a sheath, an outer conductor, an insulator, and an inner conductor, from the outside to the inside.

[0083] Optionally, the antenna type is a monopole antenna or a designated antenna, wherein the designated antenna is another antenna whose performance is improved based on antenna ground area.

[0084] The network camera provided by the present invention is described below. The network camera described below can be referred to in correspondence with the antenna described above.

[0085] Figure 7 This is a schematic diagram of the structure of the network camera provided by the present invention, as shown below. Figure 7 As shown, the network camera includes an upper cavity 701, a lower cavity 702, a sphere 703, a wire hole 704, a waterproof cover 705, and an antenna 706, wherein the antenna 706 is an antenna whose performance has been enhanced by the antenna performance enhancement method described above.

[0086] The waterproof cover plate 705 can be a waterproof cover, and the sphere includes an outer shell, a single plate, and a main plate.

[0087] Specifically, the board can be a board using the 4th generation mobile communication technology (4G) module, a board using the 5th generation mobile communication technology (5G) module, or a board using the 6th generation mobile communication technology (6G) module, etc.

[0088] Specifically, the network camera can be a dome network camera.

[0089] For example, see Figures 8 to 10 , Figure 8 This is a schematic diagram of the overall structure of the network camera provided by the present invention. Figure 9 This is a cross-sectional structural diagram of the network camera provided by the present invention. Figure 10 This is a partial structural diagram of the network camera provided by the present invention: The network camera consists of an upper cavity 1, a lower cavity 2, a sphere 3, an antenna body 4, a single board 5, a main board 6, a first radio frequency (RF) cable 7, a second RF cable 8, a cable hole 9, and a waterproof cover 10. The upper cavity 1 and lower cavity 2 are made of plastic, and the sphere 3 consists of a plastic shell, a single board 5, and a main board 6. The first RF cable 7 and the second RF cable 8 are intertwined, thereby increasing the ground area. Conductive tape is added to the ends of the first RF cable 7 and the second RF cable 8 near the antenna body. Figure 2 As shown, wrapping both RF lines with conductive tape simultaneously optimizes the low-frequency performance of the antenna, thereby improving the overall performance of the device.

[0090] See Figure 11 , Figure 11 This is a comparison chart of the transmission power before and after optimization provided by this invention: the blue line represents the transmission power of the antenna and / or network camera in Band 5 (frequency band 825-849 MHz), and the red line represents the transmission power of the antenna and / or network camera in Band 8 (frequency band 880-915 MHz). It can be seen that the transmission power is significantly improved after optimization, regardless of whether the frequency band is Band 5 or Band 8. The horizontal axis represents the total radiated power (TRP) of the transmission power, expressed in decibels per milliwatt (dBm).

[0091] This invention improves the low-frequency performance of the antenna by increasing the ground area of ​​the antenna through the addition of radio frequency (RF) lines and conductive tape. The network camera uses a monopole antenna, which theoretically requires an infinitely large ground plane for optimal performance. However, due to the antenna's inherent size, its performance often falls short of expectations. Therefore, this invention improves antenna performance without altering the antenna itself, utilizing RF lines and conductive tape.

[0092] Furthermore, in PTZ network cameras, the antenna's low-frequency performance is improved by increasing the antenna's ground area through the addition of radio frequency (RF) cables and conductive tape. This allows for an overall performance enhancement without altering the device's structure. In other words, RF performance is improved while maintaining the device's waterproofing and cruise control capabilities.

[0093] The antenna performance enhancement device provided by the present invention is described below. The antenna performance enhancement device described below can be referred to in correspondence with the antenna performance enhancement method described above.

Figure 12 As shown, the device includes the following: The addition module 1201 is configured to increase the number of radio frequency lines in the antenna, so that the antenna contains at least two radio frequency lines; Enhancement module 1202 is configured to perform an increased ground area process on the at least two radio frequency lines to enhance the performance of the antenna, the increased ground area process comprising intertwining the at least two radio frequency lines.

[0095] The antenna performance enhancement device provided by this invention utilizes at least two radio frequency (RF) lines to improve wireless performance. Compared to solutions with large antenna sizes, it shortens debugging time, reduces overall cost, and maintains the aesthetic appeal of the device. Furthermore, it enhances overall device performance without altering the structure of the antenna-using product, achieving RF performance improvement while ensuring the device's waterproofing and cruise control capabilities.

[0099] Optionally, the shielding material is conductive adhesive tape and / or a set material, wherein the shielding performance of the set material is better than that of the conductive adhesive tape.

[0100] Figure 13 This is a schematic diagram of the structure of the electronic device provided by the present invention, such as... Figure 13 As shown, the electronic device may include a processor 1310, a communications interface 1320, a memory 1330, and a communication bus 1340, wherein the processor 1310, the communications interface 1320, and the memory 1330 communicate with each other via the communication bus 1340.

Based on this understanding, the technical solution of the present invention, or the part that contributes to the prior art, or a part of the technical solution, can be embodied in the form of a software product. This computer software product is stored in a storage medium and includes several instructions to cause a computer device (which may be a personal computer, server, or network device, etc.) to execute all or part of the steps of the methods described in the various embodiments of the present invention.
