Description

Technical Field

[0001] The present application relates to the technical field of wireless communications, and in particular to an antenna device. Background Art

[0002] In the field of wireless communication equipment, the design and manufacture of antenna components are crucial to ensure the quality and stability of signal transmission. In traditional antenna component designs, the antenna cover is usually made of PC material, which is widely used due to its good light transmittance, weather resistance and processing performance. In order to firmly connect the antenna cover to the base, the prior art generally adopts the method of embedding hot-melt copper nuts inside the antenna cover and fixing the antenna cover and the base together with screws. However, there are some problems with this connection method: the hot-melt copper nuts will introduce internal stresses during the process of embedding into the antenna cover. These stresses may cause the antenna cover to crack under long-term use or environmental stress, thereby affecting the overall performance and life of the antenna.

[0003] In addition, the connection between the passive antenna and the active antenna in the antenna assembly is also a key link. The existing technology usually realizes the electrical connection between the passive antenna and the active antenna circuit board by penetrating the reflector through a PIN needle, and the active antenna circuit board is fixed to the reflector by screws, and the reflector is further connected to the base by screws. Although this multi-level and multi-connection point design ensures the stability of the structure to a certain extent, it also brings new problems. Since it is difficult to ensure perfect coplanarity and roughness of the connecting surface between the reflector and the base during the processing, these tiny unevenness may cause signal leakage, especially in the high frequency band, this leakage may be more significant. Signal leakage will not only reduce the efficiency of the antenna, but also may cause self-excitation between the passive antenna and the active antenna.

[0004] In addition, in order to ensure the sealing and waterproof performance of the antenna assembly, a sealing ring is also set between the antenna cover and the base in the prior art, and the sealing effect is achieved through the extrusion effect generated when the screws are tightened. Although this method effectively prevents the intrusion of moisture and dust to a certain extent, the complex assembly process and multiple potential leakage points still pose a challenge to production efficiency and product quality.

[0005] In summary, the design of existing antenna assemblies has problems such as poor connection reliability, poor signal integrity, and insufficient sealing and waterproof performance. Summary of the invention

[0006] Based on this, it is necessary to provide an antenna device to address the problems of poor connection reliability and poor signal integrity of existing antenna components.

[0037] Referring to FIG. 1 to FIG. 5 , FIG. 1 to FIG. 5 respectively show a schematic diagram of the structure of an antenna device and schematic diagrams of the structures of various components in an embodiment of the present application.

[0038] 1 , an antenna device provided in one embodiment of the present application includes: a base 1 , a radome 2 , a reflector 3 , a passive antenna assembly 4 , an active antenna assembly 5 and a connector cable assembly 6 .

[0039] The base 1 is used as a supporting structure of the antenna device and is made of high-strength, corrosion-resistant materials, such as aluminum alloy, to ensure the stability and durability of the device. The shape and size of the base 1 are customized according to specific application scenarios and design requirements.

[0040] In one embodiment, the antenna cover 2 is threadedly connected to the base 1 .

[0041] Specifically, the antenna cover 2 is used to protect other components inside the antenna device from being affected by the external environment. The antenna cover 2 is made of transparent or translucent materials, such as polycarbonate or glass fiber reinforced plastic, to ensure normal transmission of antenna signals.

[0042] The bottom edge of the antenna cover 2 is designed with an internal thread 20, which matches the external thread 10 on the base 1. The antenna cover 2 can be tightly connected to the base 1 by rotating it, which not only ensures the sealing, but also facilitates disassembly and maintenance. Since the threaded connection between the two is adopted, the problem of cracking of the antenna cover 2 caused by stress concentration is avoided, the connection strength is improved, and there is no need for multiple screw connections, which simplifies the installation method. In the production and processing, there is no need to perform complex processes such as hot-melt nuts, thereby reducing production costs.

[0043] The reflector 3 and the base 1 are integrated to form an integral structure, which effectively eliminates the gap between the reflector 3 and the base 1, avoids the coplanarity or roughness problem of the connecting surface between the reflector 3 and the base 1 in the traditional connection method, and thus avoids the signal leakage caused by the coplanarity or roughness problem, thereby reducing the risk of self-excitation. Specifically, the reflector 3 is formed on the top of the base 1.

[0044] In this embodiment, the reflection plate 3 is made of conductive material to effectively prevent signal leakage.

[0045] The passive antenna assembly 4 is disposed on the reflector 3 to distribute, merge, filter and other processes on the signal to ensure the transmission quality of the signal to meet the requirements of different application scenarios.

[0046] The active antenna assembly 5 is connected to the passive antenna assembly 4 to realize the functions of receiving, amplifying and transmitting signals.

[0047] The connector cable assembly 6 passes through the base 1 and is connected to the active antenna assembly 5. The connector cable assembly 6 includes two parts: a connector and a cable. The connector is used to achieve electrical connection with an external device, and the cable is used to transmit signals to ensure the transmission characteristics, anti-interference ability and durability of the signal, and ensure stable communication between the antenna device and the external device.

[0048] As described above, the antenna device has the advantages of simple structure, easy installation, stable performance, etc. It avoids the problem of cracking of the antenna cover 2 due to stress concentration, improves the connection strength, avoids the problem of signal leakage, reduces the risk of self-excitation, and meets the needs of various complex application scenarios.

[0049] FIG2 is a schematic diagram of the assembly of the antenna cover 2 and the base 1 in an embodiment of the present application. In some embodiments, the antenna cover 2 is provided with an internal thread 20 on the inner wall at the bottom end, and the base 1 is provided with an external thread 10 matching the internal thread 20 on the outer wall at the top end near the antenna cover 2.

[0050] Specifically, an outer fine thread is provided on the top outer wall of the base 1, and an inner fine thread is provided on the bottom inner wall of the antenna cover 2, and the inner fine thread matches the outer fine thread to ensure that the two are tightly matched.

[0051] Since the base 1 and the antenna cover 2 are connected by a threaded connection method without using hot melt nuts and screws, the problem of cracking of the antenna cover 2 due to stress concentration is avoided and the connection strength is improved. The antenna cover 2 and the base 1 are only connected by a threaded connection without multiple screw connection points, making the installation method simpler and faster. In the production and processing process, complex processes such as hot melt nuts are not required, which reduces production costs and improves production efficiency.

[0052] In one embodiment, the connection between the antenna cover 2 and the base 1 is sealed. Specifically, a sealing material such as silicone is applied between the connection between the antenna cover 2 and the base 1 to ensure the sealing of the connection between the two.

[0053] As shown in Figure 3, Figure 3 is a schematic diagram of the structure of the base 1 in an embodiment of the present application. In some embodiments, a reflector 3 is integrated on the upper wall of the base 1 close to one end of the antenna cover 2.

[0054] Specifically, the upper wall of the base 1 close to one end of the antenna cover 2 is integrated with a reflector 3 to form a complete circular structure, thereby ensuring effective reflection and focusing of the signal.

[0055] The reflector 3 and the base 1 are designed as an integrated unit. The base 1 having the function of the reflector 3 is manufactured by machining and other processes, eliminating the gap between the reflector 3 and the base 1, avoiding the problem of signal leakage and reducing the risk of self-excitation. The radome 2 is tightly mounted on the base 1 and forms a certain space with the base 1 for accommodating the passive antenna assembly 4.

[0056] As described above, the base 1 and the reflector 3 are combined into one, eliminating the gap between the reflector 3 and the base 1, avoiding the problem of signal leakage, and reducing the risk of self-excitation. At the same time, since the reflector 3 and the base 1 are designed in an integrated manner, the structure of the antenna device is more compact and stable, and its overall performance and reliability are improved.

[0057] In one embodiment, the passive antenna assembly 4 is disposed in a space formed between an upper wall of the base 1 and the antenna cover 2 .

[0058] Specifically, the passive antenna assembly 4 is arranged in the space formed between the upper wall of the base 1 and the antenna cover 2, which helps to improve the signal transmission quality. In addition, since the active antenna circuit board is installed in the above space, there is no need to set up a separate installation space, which helps to control the overall size of the antenna device.

[0059] As shown in Figure 1, Figure 1 is an exploded schematic diagram of an antenna device in an embodiment of the present application. In some embodiments, the antenna device includes a PIN pin 7, the active antenna component 5 is arranged on a side of the reflector 3 close to the inside of the base 1, one end of the PIN pin 7 is connected to the active antenna component 5, and the other end passes through the upper wall of the base 1 and is connected to the passive antenna component 4.

[0060] Specifically, the PIN pin 7 is the connection medium between the active antenna component 5 and the passive antenna component 4. One end of the PIN pin 7 is connected to some components in the active antenna component 5, and the other end passes through the reserved hole on the upper wall of the base 1 and is connected to the connection port on the passive antenna component 4.

[0061] In conjunction with Figure 1, Figure 1 is an exploded schematic diagram of an antenna device in an embodiment of the present application. In some embodiments, the antenna device further includes a cover plate 8, the cover plate 8 is connected to the bottom end of the base 1; the cover plate 8 is provided with a breathable valve 80, and the breathable valve 80 is connected to the inside of the base 1.

[0062] Specifically, the cover plate 8 is connected to the bottom end of the base 1 to close the opening of the base 1 and protect the electronic components inside the antenna device from interference and damage from the external environment.

[0063] The cover plate 8 is provided with a breathable valve 80, which is connected to the inside of the base 1 to ensure that when the air pressure changes, the air pressure inside and outside the cavity of the base 1 can be balanced in time, eliminating the siphon phenomenon and preventing water from entering the cavity of the base 1. The air valve 80 is provided with a microporous membrane or breathable material inside to allow air to pass through but prevent external moisture and dust from entering the antenna device, thereby improving the waterproof, dustproof and breathable performance of the antenna device and ensuring the stability and reliability of the antenna device in harsh environments.

[0064] As shown in Figure 4, Figure 4 is another schematic diagram of the structure of the base 1 in an embodiment of the present application. In some embodiments, a seal 81 is provided at the connection between the bottom end of the base 1 and the cover plate 8, and a sealing groove 11 is provided on the inner wall of the bottom end of the base 1, and the seal 81 is embedded in the sealing groove 11.

[0065] Specifically, the sealing member 81 is a sealing ring, which is made of an elastic material, such as rubber, silicone, etc., and has good elasticity and sealing performance. The sealing groove 11 is arranged along the inner wall circumference of the bottom end of the base 1, and the sealing ring is embedded in the sealing groove 11. When the cover plate 8 is connected to the bottom end of the base 1, the annular sealing ring is squeezed and deformed, filling the gap between the cover plate 8 and the bottom end of the base 1, achieving a good sealing effect, and extending the service life of the antenna device.

[0066] As shown in FIG5 , FIG5 is a schematic diagram of the structure of the cover plate 8 in an embodiment of the present application. In some embodiments, the connector cable assembly 6 is disposed on the cover plate 8, and a through hole 82 is disposed on the cover plate 8; the active antenna assembly 5 includes an active antenna circuit board, and one end of the connector cable assembly 6 passes through the through hole 82 to be connected to the active antenna circuit board.

[0067] Specifically, the active antenna circuit board integrates related circuits such as signal amplification and processing. The connector cable assembly 6 is used to connect the antenna device with an external device to achieve signal transmission. In this embodiment, one end of the connector cable assembly 6 is connected to the external device through a specific connector, and the other end is connected to the active antenna circuit board through a through hole 82 on the cover plate 8, so as to achieve effective fixation and connection of the connector cable assembly 6, achieve stable signal transmission, and help optimize the overall structure of the antenna device, thereby improving its stability and reliability.

[0068] The connector cable assembly 6 uses high-quality cables and connectors to ensure stable signal transmission and long-term reliability. In this embodiment, the connector cable assembly 6 is mounted on the cover plate 8 by a fixing structure. The fixing structure may include components such as clips, screws, and buckles, which are used to fix the connector cable assembly 6 on the cover plate 8 to prevent it from loosening or falling off, and ensure that it can be closely matched with the connector cable assembly 6 to achieve effective fixation.

[0069] In the specific assembly process, first ensure that the base 1, active antenna assembly 5 and passive antenna assembly 4 have been correctly installed and connected according to the design requirements. Then, the PIN pin 7 passes through the upper wall of the base 1 to connect the passive antenna assembly 4 with the active antenna assembly 5. Next, the antenna cover 2 is connected to the base 1 by threading. After that, the connector cable assembly 6 passes through the through hole 82 on the cover plate 8 and is connected to the active antenna assembly 5, and the cover plate 8 is installed at the bottom end of the base 1, and the seal 81 is installed at the same time to ensure a tight connection and good sealing between the cover plate 8 and the base 1. Finally, check whether all connections and fixations are firm and reliable to ensure that the antenna device can work normally.

[0070] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
