Description

Technical Field

[0001] This application relates to the field of communication equipment technology, and in particular to a portable ultra-wideband antenna device for a four-in-one 5G backpack. Background Technology

[0002] With the increasing application of 5G technology in military, emergency communications and other fields, individual soldier communication devices need to achieve high-speed, low-latency, and high-reliability multi-mode communication in complex environments. This places higher demands on antenna performance: it needs to cover a wider frequency band, support multiple communication modes (such as 5G main communication, satellite navigation, self-organizing networks, etc.), and at the same time meet stringent requirements such as portability, robustness and low power consumption.

[0003] Most commercially available single-soldier antennas are single-function and cannot simultaneously meet the requirements of ultra-wideband, multi-mode, and miniaturization. For example, while some antennas cover part of the 5G frequency band, they cannot achieve coordinated operation of multiple functions on a single antenna; while using multiple independent antennas increases the size, weight, and complexity of the equipment, making it inconvenient for individual soldiers to carry and use. Transmission rates are significantly affected in harsh environments, making it difficult to meet the low latency and high throughput requirements of 5G devices. Therefore, this application proposes a four-in-one 5G backpack portable ultra-wideband antenna device. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a four-in-one 5G backpack portable ultra-wideband antenna device to solve the technical problems mentioned in the background art.

[0005] The above-mentioned objective of this application is achieved through the following technical solution: a four-in-one 5G backpack portable ultra-wideband antenna device, including an antenna housing and a multi-in-one connector disposed on the antenna housing, the multi-in-one connector also being electrically connected to a radio frequency connector, and an antenna radiating element group electrically connected to the radio frequency connector inside the antenna housing.

[0006] Furthermore, the antenna radiating unit group includes a first antenna, a second antenna, a third antenna, and a fourth antenna arranged sequentially at intervals and connected in the vertical direction of the antenna housing.

[0007] By adopting the above technical solution, the multi-in-one connector in this application integrates the feed lines of four antenna units onto one interface, simplifying the connection with the RF connector, achieving a compact structure, and integrating four independent antenna systems into a lightweight fiberglass rod, avoiding the cumbersome and bulky nature of externally mounted multiple antennas, perfectly meeting the combat or emergency needs of individual soldiers carrying and moving quickly.

[0008] Furthermore, at least one centering ring is provided between the multi-in-one connector and the inner wall of the antenna housing to ensure that the multi-in-one connector is aligned with the axis of the antenna housing.

[0009] Furthermore, the number of the guide rings is three, located at the tail end and middle section of the multi-in-one connector, respectively.

[0010] By adopting the above technical solution, the performance of high-frequency antennas (such as VSWR, resonant frequency, and radiation pattern) is extremely sensitive to the precise position and orientation of their internal radiators (oscillators). Even a slight eccentricity or tilt of the connector within the fiberglass tube will cause the antenna oscillator to become misaligned, effectively altering the carefully designed electromagnetic model. The multiple support points formed by the three centering rings act like a high-precision "guide rail" for the connector, ensuring that the core components of each manufactured antenna are absolutely centered and in their theoretically designed positions. This guarantees a high degree of consistency and repeatability in product performance, eliminating performance degradation caused by assembly errors.

[0011] Furthermore, a silicone sealing plug is provided between the multi-in-one connector and the inner wall of the antenna housing.

[0012] By employing the above technical solution, the antenna is exposed to rain, humid air, and even salt spray in outdoor applications. The silicone material, with its excellent elasticity and sealing properties, fills all the tiny gaps between the connector and the inner wall of the housing, forming a reliable waterproof and airtight barrier. This effectively prevents moisture and humidity from penetrating the antenna's interior, avoiding short circuits, oxidation, or electrochemical corrosion of the delicate internal PCB circuitry and solder joints due to moisture, thus ensuring the antenna's electrical safety and stable performance throughout its entire lifespan.

[0013] Furthermore, the antenna housing is made of fiberglass.

[0014] By employing the above technical solutions, fiberglass exhibits excellent penetration of radio waves, especially the high-frequency microwaves used in 5G. Its dielectric constant is typically between 3 and 4, and its loss tangent is very small. This characteristic makes the antenna shroud (i.e., the radome) almost "transparent" to the electromagnetic waves radiated internally, resulting in minimal signal attenuation and phase distortion. This maximizes the preservation of the inherent radiation performance of the internal precision antenna design (such as gain, beamform, and impedance matching), ensuring that simulation results can be perfectly reproduced in the real world. This is a key prerequisite for achieving ultra-wideband and high-gain specifications.

[0015] In summary, this application offers the following beneficial technical effects: The portable ultra-wideband antenna device in the four-in-one 5G backpack described in this application integrates four antenna units into a single device through a multi-in-one connector. The vertically spaced arrangement design ensures the performance of the 4×4 MIMO multi-antenna technology while significantly reducing the device's size, achieving a perfect balance between high performance and high integration. A precision positioning system composed of three centering rings ensures that the antenna element is always in its theoretically designed position, effectively preventing performance degradation due to assembly deviations. Combined with the low dielectric and low loss characteristics of the fiberglass shell, the inherent performance of the antenna design is maintained to the maximum extent, ensuring that simulation results are perfectly reflected in practical applications. A protective system composed of silicone sealing plugs effectively prevents the corrosion of internal circuits by environmental factors such as moisture and humidity. Combined with the inherent corrosion resistance and anti-aging properties of fiberglass, the device can adapt to various harsh outdoor environments, significantly improving product reliability. The combination of lightweight design and compact structure greatly enhances the portability of the equipment, while the fully sealed structure and robust shell design ensure stable performance under field conditions. The flexible yet robust positioning system ensures assembly accuracy while providing necessary tolerance compensation, significantly improving production yield and guaranteeing high product performance consistency during mass production. These technological advantages eliminate the need for multiple external antennas, greatly simplifying the deployment process of individual soldier communication systems. Its superior electromagnetic performance provides reliable support for high-speed services such as high-definition video transmission and real-time data interaction. Its long service life and stable performance significantly reduce maintenance costs throughout its lifecycle, successfully solving the technical challenges of balancing performance, size, and reliability inherent in traditional antennas.

[0018] The present application will be further described in detail below with reference to the accompanying drawings.

[0019] Example, refer to Figures 1-10 A portable ultra-wideband antenna device for 5G backpacks, comprising an antenna housing 1 and a multi-in-one connector 2 disposed on the antenna housing 1, the multi-in-one connector 2 being electrically connected to a radio frequency connector 21, and an antenna radiating element group electrically connected to the radio frequency connector 21 inside the antenna housing 1. The antenna radiating element group includes a first antenna 11, a second antenna 12, a third antenna 13, and a fourth antenna 14 arranged sequentially at intervals in the vertical direction of the antenna housing 1.

[0020] In this application, the multi-in-one connector 2 integrates the feed lines of four antenna units onto one interface, simplifying the connection with the RF connector 21 and achieving a compact structure. It integrates four independent antenna systems into a lightweight fiberglass rod, avoiding the cumbersome and bulky nature of externally mounted multiple antennas, perfectly meeting the combat or emergency needs of individual soldiers carrying and moving quickly.

[0021] In this embodiment, at least one centering ring 22 is provided between the multi-in-one connector 2 and the inner wall of the antenna housing 1 to ensure that the multi-in-one connector 2 and the antenna housing 1 are aligned axially. There are three centering rings 22, located at the tail end and middle section of the multi-in-one connector 2, respectively.

[0022] The performance of high-frequency antennas (such as VSWR, resonant frequency, and radiation pattern) is extremely sensitive to the precise position and orientation of their internal radiators (oscillators). Even a slight eccentricity or tilt within the fiberglass tube will cause the antenna oscillator to become misaligned, effectively altering the carefully designed electromagnetic model. The multiple support points formed by the three centering rings 22 act like a high-precision "guide rail" for the connector, ensuring that the core components of each manufactured antenna are perfectly centered and in their theoretically designed positions. This guarantees high consistency and repeatability of product performance and eliminates performance degradation caused by assembly errors.

[0023] In this embodiment, a silicone sealing plug 23 is also provided between the multi-in-one connector 2 and the inner wall of the antenna housing 1. In outdoor applications, the antenna will be exposed to rain, humid air, and even salt spray. The silicone material has excellent elasticity and sealing properties; it fills all the tiny gaps between the connector and the inner wall of the housing, forming a reliable waterproof and airtight barrier. This effectively prevents moisture and humidity from penetrating the antenna, avoiding short circuits, oxidation, or electrochemical corrosion of the delicate internal PCB circuitry and solder joints due to moisture, thereby ensuring the electrical safety and stable performance of the antenna throughout its entire lifespan.

[0024] In this embodiment, the antenna housing 1 is made of fiberglass. Fiberglass has excellent penetration for radio waves, especially the high-frequency microwaves used in 5G. Its dielectric constant is typically between 3 and 4, and its loss tangent is very small. This characteristic makes the antenna housing 1 (i.e., the radome) almost "transparent" to the electromagnetic waves radiated internally, resulting in minimal signal attenuation and phase distortion. This maximizes the preservation of the inherent radiation performance of the internal precision antenna design (such as gain, beamform, and impedance matching), ensuring that simulation results can be perfectly reproduced in the real world. This is a key prerequisite for achieving ultra-wideband and high-gain specifications.

[0025] Specific implementation process: This application integrates four independent antenna systems (first antenna 11 to fourth antenna 14) into a lightweight fiberglass antenna housing 1 through the design concepts of "high integration" and "precision structuring". The multi-in-one connector 2 serves as the structural core and electrical hub, integrating the feed lines of the four antenna units into one unit and connecting to external devices through the RF connector 21, fundamentally achieving a compact structure.

[0026] Three centering rings 22 located at the tail and middle of the connector ensure that the connector and the antenna housing 1 are perfectly aligned. This ensures that the four antenna elements mounted on it are always in the precise positions designed in theory, resulting in highly consistent antenna performance in mass production and eliminating performance degradation problems such as VSWR deterioration and radiation pattern distortion caused by assembly misalignment.

[0027] The silicone sealing plug 23, added to the core ring 22 system, provides comprehensive environmental protection. Its excellent elastic sealing effectively prevents the intrusion of rainwater and moisture, protecting the internal precision circuits from corrosion and short circuit threats. At the same time, it can also compensate for manufacturing tolerances, absorb vibration and shock, and work in synergy with the core ring 22 to improve the smoothness of assembly and the long-term durability of the product.

[0028] The fiberglass antenna housing 1 plays a crucial role. Its low dielectric constant and low loss tangent make it almost "transparent" to ultra-wideband electromagnetic waves from 698MHz to 5200MHz, with minimal attenuation and distortion during signal penetration. This maximizes the preservation of the inherent high performance of the internal antenna design and ensures the achievement of high gain and good impedance matching.

[0029] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
