Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wireless communication, in particular to an antenna device. BACKGROUND

[0002] In the field of wireless communication devices, the design and manufacture of antenna assemblies are crucial for ensuring the quality and stability of signal transmission. In traditional antenna assembly designs, the radome is typically made of PC material, which is widely used due to its good light transmission, weather resistance, and processing performance. To securely connect the radome to the base, the existing technology generally uses the method of embedding hot-melt copper nuts inside the radome, and then fixing the radome and the base together with screws. However, this connection method has some problems: the hot-melt copper nuts may introduce internal stress during the embedding process, and these stresses may cause the radome to crack under long-term use or environmental stress, thereby affecting the overall performance and lifespan 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 achieves electrical connection between the passive antenna and the active antenna circuit board by penetrating the reflector plate with a PIN pin, and the active antenna circuit board is fixed to the reflector plate with screws, and the reflector plate is further connected to the base with screws. Although this multi-level, multi-connection point design ensures the stability of the structure to some extent, it also brings new problems. Since the connection surface between the reflector plate and the base is difficult to guarantee perfect coplanarity and roughness during processing, these small irregularities may cause signal leakage, especially at high frequencies, which may be more pronounced. Signal leakage not only reduces 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, the existing technology also sets a sealing ring between the radome and the base, and achieves the sealing effect through the extrusion effect generated by screw tightening. Although this method can prevent the intrusion of water and dust to some extent, the complex assembly process and multiple potential leakage points still pose challenges to production efficiency and product quality.

[0005] In summary, the existing antenna assembly design has problems such as poor connection reliability, poor signal integrity, and insufficient sealing and waterproof performance. INNOVATION CONTENT

[0006] Therefore, it is necessary to provide an antenna device to solve the problems of poor connection reliability and poor signal integrity of the existing antenna assembly.

[0037] Referring to Figures 1 to 5 , Figures 1 to 5 The structure schematic diagram of the antenna device and the structure schematic diagram of each component in an embodiment of the present application are shown respectively.

[0038] Referring to Figure 1 , an antenna device provided by an embodiment of the present application comprises a base 1, a radome 2, a reflector plate 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 support structure of the antenna device and is made of high-strength and 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 of the embodiments, the radome 2 is threadedly connected with the base 1.

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

[0042] The bottom edge of the radome 2 is designed with internal threads 20, which are matched with external threads 10 on the base 1. By rotating the radome 2, the radome 2 can be tightly connected with the base 1, which not only ensures the sealing property but also facilitates disassembly and maintenance. Since the radome 2 and the base 1 are connected by threads, the problem of cracking of the radome 2 caused by stress concentration is avoided, the connection strength is improved, and multiple screws are not needed for connection, which simplifies the installation method and eliminates the need for complex processes such as hot melting of nuts in production and processing, thereby reducing production costs.

[0043] The reflector plate 3 is integrally arranged with the base 1 to form a whole structure, which effectively eliminates the gap between the reflector plate 3 and the base 1 and avoids the problem of coplanarity or roughness of the connection surface between the reflector plate 3 and the base 1 in the traditional connection mode, thereby reducing signal leakage and self-excitation risk. Specifically, the reflector plate 3 is formed at the top end of the base 1.

[0044] In the embodiment, the reflector plate 3 is made of conductive material, effectively preventing signal leakage.

[0045] The passive antenna assembly 4 is arranged on the reflector plate 3, and performs signal distribution, combination, filtering and other processes to ensure the transmission quality of the signal and meet the requirements of different application scenarios.

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

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

[0048] As described above, the antenna device has the advantages of simple structure, convenient installation and stable performance, avoids the problem of cracking of the radome 2 caused by stress concentration, improves the connection strength, avoids signal leakage, reduces the risk of self-excitation, and meets the requirements of various complex application scenarios.

[0049] In combination with the drawings, Figure 2 shown, Figure 2 is an assembly diagram of the radome 2 and the base 1 in an embodiment of the present application. In some embodiments, an inner thread 20 is arranged on the inner wall of the bottom end of the radome 2, and an outer thread 10 matched with the inner thread 20 is arranged on the outer wall of the top end of the base 1 close to the radome 2.

[0050] Specifically, an outer fine thread is arranged on the outer wall of the top end of the base 1, and an inner fine thread is arranged on the inner wall of the bottom end of the radome 2, and the inner fine thread is matched with the outer fine thread to ensure that the two are tightly matched.

[0051] Since the threaded connection is adopted between the base 1 and the radome 2, and hot melt nuts and screws are not used, the problem of cracking of the radome 2 caused by stress concentration is avoided, and the connection strength is improved. Only threaded connection is adopted between the radome 2 and the base 1, and there is no multiple screw connection points, so that the installation method is more simple and convenient. In the production and processing process, complex processes such as hot melt nuts are not required, which reduces the production cost and improves the production efficiency.

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

[0053] In combination with the drawings, Figure 3 shown, Figure 3The figure is a structural schematic diagram of the base 1 in an embodiment of the present application. In some embodiments, the base 1 is integrally provided with a reflecting plate 3 on the upper wall of one end of the radome 2.

[0054] Specifically, the base 1 is integrally provided with the reflecting plate 3 on the upper wall of one end of the radome 2, forming a complete circular structure, which ensures effective reflection and focusing of signals.

[0055] The reflecting plate 3 and the base 1 are designed in an integrated manner, and the base 1 with the function of the reflecting plate 3 is manufactured through machining and other processes, eliminating the gap between the reflecting plate 3 and the base 1, avoiding 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, which is used to accommodate the passive antenna assembly 4.

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

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

[0058] Specifically, the passive antenna assembly 4 is arranged in the space formed between the upper wall of the base 1 and the radome 2, which helps to improve the signal transmission quality. In addition, since the active antenna circuit board is installed in the above-mentioned space, it is not necessary to separately provide an installation space, which helps to control the overall size of the antenna device.

[0062] Specifically, the cover plate 8 is connected with the bottom end of the base 1, used for closing the opening of the base 1, protecting the electronic components inside the antenna device from the interference and damage of the external environment.

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

The sealing groove 11 is circumferentially arranged along the inner wall 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 with the bottom end of the base 1, the annular sealing ring is extruded to deform, filling the gap between the cover plate 8 and the bottom end of the base 1, achieving good sealing effect and prolonging the service life of the antenna device.
