This structure has become an industry standard and is widely used in various microwave communication systems.

[0004] Although the split design has its advantages, it also has problems such as large structural volume and poor stability. Utility Model Content

This allows the isolation cover to block radiation emitted by the radiator, preventing the radiator from affecting the RF components. Simultaneously, because the radiator is connected to the isolation cover, the connection between the isolation cover and the housing defines a cavity that accommodates the antenna components.

[0015] According to the above technical solution, the duplexer can isolate the transmission and reception frequency bands, enabling the antenna device to simultaneously transmit and receive signals on the same radiator, thus improving the utilization efficiency of the radiator. The working components can effectively increase the functionality of the antenna device.

[0016] In some embodiments, the antenna device further includes a waveguide clip that passes through an isolation cover and is connected to a duplexer and a radiator to enable signal transmission between the duplexer and the radiator.

[0020] In some embodiments, the housing has multiple heat dissipation protrusions on the side away from the isolation cover; and / or, the isolation cover is a metal cover.

Therefore, they should not be construed as limitations on this application.

[0029] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0030] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances. Furthermore, when describing pipelines or channels, the terms "connection" and "linkage" as used in this application have the meaning of establishing electrical conductivity. The specific meaning needs to be understood in conjunction with the context.

[0031] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0032] This application provides a base station, which includes an antenna device. The antenna device is a key device for base station signal transmission. The antenna device converts guided waves on the base station signal transmission line into electromagnetic waves in the external environment for radiation, or converts electromagnetic waves in the external environment into guided waves and transmits them through the base station signal transmission line. The antenna device directly affects the communication quality, thereby achieving effective transmission of communication signals.

[0033] In some possible embodiments, the base station may also be equipped with a power system, a processing device, and a support frame to achieve efficient and stable operation. The processing device can process and analyze the signals received by the antenna device, and operators can also operate the processing device to control the antenna device to receive or emit electromagnetic waves. The main function of the power system is to provide electrical energy for the antenna device and processing device to ensure the stable operation of the base station. For example, the power system may consist of multiple devices such as AC power supply, conductive cables, and transformers, or it may use a combination of batteries and conductive components. For example, the processing device may be a microcontroller or a computer; this application does not limit the specific structure of the processing device.

[0034] The antenna device is mounted on a support frame, which elevates the antenna device to a certain height above the ground. This configuration effectively reduces obstruction from buildings, terrain, and other obstacles, expands the signal propagation range, and reduces multipath interference, thereby improving communication quality and coverage efficiency. Simultaneously, the support frame provides stable support, preventing antenna displacement or damage due to wind, vibration, or environmental factors, ensuring long-term stable operation and meeting the stringent signal reliability requirements of base stations. The support frame can be a pole-shaped frame, with the antenna device mounted on it using bolts or load-bearing components. The support frame can also be a tower. This application does not limit the specific structure of the support frame; the choice of support frame can be based on actual needs such as cost and environment. It should be noted that the base station of this application is not limited to only including a power system, processing device, and support frame. The number of devices included in the base station can be increased or decreased according to the functional requirements and installation environment. This application does not limit the specific structure of the base station.

[0035] like Figure 1 and Figure 2 As shown, in some embodiments, the antenna device includes a housing 1, an isolation cover 2, a radiator 3, and a radio frequency component 4; the housing 1 and the isolation cover 2 are connected to define a receiving cavity, the radio frequency component 4 is disposed inside the receiving cavity so that the housing 1 and the isolation cover 2 protect the radio frequency component 4, and the radiator 3 is disposed outside the receiving cavity and connected to the radio frequency component 4 disposed inside the receiving cavity.

[0036] In some possible embodiments, the housing 1 may be provided with an opening structure, through which the radio frequency component 4 can be disposed inside the housing 1. The isolation cover 2 can cover the opening of the housing 1 to cover the opening, so that the isolation cover 2 and the housing 1 form an accommodating cavity, isolating the radio frequency component 4 from the external environment to protect the radio frequency component 4.

[0037] In some possible embodiments, the housing 1 can be a rectangular housing 1, with a rectangular opening on one of its rectangular faces. The isolation cover 2 can be a rectangular cover body, covering the rectangular opening to isolate the internal space of the housing 1 from the external environment. In other possible embodiments, the housing 1 can be a column, and the isolation cover 2 can be a circular isolation cover 2. This application does not limit the specific structure of the isolation cover 2 and the housing 1, and the specific selection can be made according to the actual needs of the usage environment and process. For example, the connection between the isolation cover 2 and the housing 1 can be a bolt connection, or the isolation cover 2 and the housing 1 can be snapped together by a slot. The isolation cover 2 and the housing 1 can be detachably connected to facilitate the removal of the isolation cover 2 from the housing 1 by the operator, so as to facilitate the operator's maintenance of the antenna device or replacement of internal components. This application does not limit the specific connection method between the housing 1 and the isolation cover 2, and the selection can be made according to the actual situation of process and cost.

[0038] The primary function of the radiator 3 is to emit or receive electromagnetic waves. For example, the radiator 3 can be made of a metallic material capable of transmitting signals to achieve signal transmission and reception. The radiator 3 can also be an antenna radiating element. This application does not limit the specific structure of the radiator 3; it can be selected based on actual conditions such as manufacturing processes and antenna performance. The radiator 3 and the radio frequency component 4 need to be connected for signal transmission so that the radiator 3 can transmit electrical signals with the radio frequency component 4.

[0039] The isolation cover 2 has the ability to isolate radiation. This means that when electromagnetic waves are projected onto the isolation cover 2, it can block them. The radiator 3 is connected to the isolation cover 2 and located outside the accommodating cavity. This allows the electromagnetic waves emitted by the radiator 3 to be isolated from the accommodating cavity by the isolation cover 2, effectively preventing interference from the electromagnetic waves emitted by the radiator 3 to the components installed inside the accommodating cavity. The orthographic projection of the radiator 3 onto the isolation cover 2 is located inside the isolation cover 2. This means that when viewing the isolation cover 2 from the side away from the housing 1, the radiator 3 is located inside the isolation cover 2. This allows the isolation cover 2 to completely block the electromagnetic waves emitted by the radiator 3 towards the accommodating cavity, further reducing the influence of the radiator 3 on the interior of the accommodating cavity. The radiator 3 can emit electromagnetic waves away from the accommodating cavity to achieve the signal transmission and reception functions of the antenna device.

[0040] For example, the isolation cover 2 may be provided with a slot, through which the radiator 3 is connected to the isolation cover 2. Alternatively, the radiator 3 may be fixed to the isolation cover 2 with adhesive. This application does not limit the specific connection method between the radiator 3 and the isolation cover 2, and the method can be selected according to actual conditions such as process and cost.

[0041] The radio frequency (RF) component 4 is primarily responsible for signal generation and processing, enabling the processed signal to be transmitted to the radiator 3 for emission. The RF component 4 can also process signals received by the radiator 3 from other antenna devices or base stations. In some possible embodiments, the accommodating cavity may also contain a baseband component 701. The RF component 4 can modulate the baseband signal from the baseband component 701 into a high-frequency RF signal, amplify it, and then transmit it to the radiator 3 for radiated emission. Simultaneously, the RF component 4 can also filter, amplify, and demodulate the weak RF signals received by the radiator 3, converting them into baseband signals for processing in the base station's processing unit. The RF device also performs impedance matching, frequency selection, and power control functions, ensuring efficient and stable signal transmission between the radiator 3 and other components of the antenna device, which is a crucial step in achieving high-quality wireless communication.

[0042] In some related technologies, the strong electromagnetic field emitted by the radiator 3 may enter the radio frequency circuit of the radio frequency component 4 through spatial coupling or conduction paths, leading to signal crosstalk, local oscillator leakage, or decreased receiving sensitivity. If the radiator 3 and the radio frequency component 4 are close together, some electromagnetic energy may be radiated back to the feed network or radio frequency chip, causing self-oscillation, increased noise, or nonlinear distortion, thereby affecting signal quality and system stability. However, in this application, since the isolation cover 2 can block the strong electromagnetic field emitted by the radiator 3, the isolation cover 2 isolates the radiator 3 from the radio frequency component 4, so that the electromagnetic waves emitted by the radiator 3 are blocked outside the accommodating cavity, effectively reducing the impact of the radiator 3 on the radio frequency component 4.

[0043] The housing 1 and the isolation plate are connected to form a cavity. The isolation cover 2 isolates radiation. The radiator 3 is located outside the cavity and connected to the isolation cover 2, while the radio frequency component 4 is located inside the cavity. This allows the isolation cover 2 to block the radiation emitted by the radiator 3, preventing the radiator 3 from affecting the radio frequency component 4. Simultaneously, since the radiator 3 is connected to the isolation cover 2, the connection between the isolation cover 2 and the housing 1 defines a cavity that accommodates the antenna components. This integrates the radiator 3, housing 1, isolation cover 2, and radio frequency component 4 into a single unit, effectively increasing the structural stability of the antenna device.

[0044] like Figures 1 to 3 As shown, in some embodiments, the radiator 3 has a plate-like structure, which enables the radiator 3 to have advantages such as compact structure, strong directivity, high gain, and ease of installation. In some possible embodiments, the isolation cover 2 may have a mounting plane on the side opposite to the housing 1, and the radiator 3 is attached to the mounting plane to make the antenna device structure more compact. Exemplarily, the radiator 3 can be a rectangular plate or a circular plate; the specific structure of the radiator 3 is not limited, and can be selected according to the performance requirements of the antenna device and the actual situation such as manufacturing process.

[0045] Multiple waveguide slots 301 are provided on the surface of the radiator 3 plate. The waveguide slots 301 are used to confine and transmit electromagnetic waves. The waveguide slots can be elongated cracks on the surface of the radiator 3 plate. Waveguide slots 301 can be provided on one or both surfaces of the radiator 3 plate. This application does not limit the specific arrangement of the waveguide slots; the arrangement can be selected according to the performance requirements and manufacturing process of the antenna device. In some possible embodiments, the orthographic projection of the waveguide slot on the surface of the radiator 3 plate can be rectangular. For ease of manufacturing, the two ends of the rectangle along its length can be rounded. Multiple waveguide slots can be arranged in a rectangular array on the surface of the radiator 3 plate.

[0046] The waveguide slots on the surface of radiator 3 primarily serve the functions of radiation and radiation control. By precisely slotting the surface of radiator 3, the electromagnetic wave energy transmitted within radiator 3 is radiated out in a specific direction and polarization, achieving directional beam output. The waveguide slot design allows for precise control of the radiation phase, amplitude, and direction, offering advantages such as high power capacity, low loss, compact structure, and good environmental stability. Furthermore, the slot array can achieve high gain characteristics through optimized layout, enabling the antenna device to meet high-performance requirements and effectively improving its reliability.

[0047] In some embodiments, the ratio of the projected area of ​​the waveguide slot 301 on the radiator 3 plate to the surface area of ​​the radiator 3 plate is greater than or equal to 0.02 and less than or equal to 0.05. For example, the ratio can be 0.02, 0.03, or 0.05. This setting helps to achieve a good balance of electromagnetic performance while ensuring sufficient radiation efficiency. If the ratio of the projected area of ​​the waveguide slot 301 on the radiator 3 plate to the surface area of ​​the radiator 3 plate is too small, it will lead to insufficient radiation intensity, affecting gain and bandwidth. If the ratio of the projected area of ​​the waveguide slot 301 on the radiator 3 plate to the surface area of ​​the radiator 3 plate is too large... The ratio of the projected area of ​​the slot on the surface of radiator 3 to the surface area of ​​radiator 3 is greater than or equal to 0.02. This ensures that the slot can effectively radiate energy and maintain a stable radiation direction, while also reducing interference with the transmission of the main waveguide mode, reducing insertion loss, and improving the overall efficiency and reliability of the antenna device.

[0048] In other possible embodiments, the radiator may also be a columnar radiator. This application does not limit the specific structure of the radiator, and it can be selected according to cost and the performance requirements of the antenna device.

[0049] like Figure 1 and Figure 2As shown, in some embodiments, the antenna device further includes a protective component 5. To ensure that the radiator 3 can receive or generate electromagnetic waves, the radiator 3 needs to be located outside the accommodating cavity. To ensure the service life of the antenna device in outdoor environments, the protective component 5 is disposed on the side of the isolation cover 2 away from the housing 1 and is connected to the isolation cover 2. The radiator 3 is disposed between the isolation cover 2 and the protective component 5, so that the protective component 5 can cover the radiator 3 at least on the side of the isolation cover 2 away from the housing 1, thereby providing protection for the radiator 3. It should be noted that it is necessary to ensure that the electromagnetic waves emitted by the radiator 3 can pass through the protective component 5 to reduce the influence of the protective component 5 on the radiator 3.

[0050] For example, the protective component 5 and the isolation cover 2 can be connected by a slot, or the protective component 5 can be connected to the isolation cover 2 by adhesive. The protective component 5 and the isolation cover 2 can be detachably connected so that the operator can remove the protective component 5 from the isolation cover 2 so that the operator can replace or repair the radiator 3. This application does not limit the specific connection method between the protective component 5 and the isolation cover 2, and can be selected according to actual needs such as cost and process.

[0051] In some possible embodiments, the protective component 5 can be a waveguide, and the protective component 5, radiator 3, and isolation cover 2 are stacked. This arrangement facilitates the compactness and functional integration of the antenna device. The stacked design of the waveguide, protective component 5, and radiator 3 optimizes the guidance and radiation path of electromagnetic waves, allowing the electromagnetic waves emitted by the radiator 3 to diverge away from the isolation cover 2 and pass through the waveguide. The protective component 5 enhances environmental tolerance; the radiator 3 is located in the central layer, ensuring efficient radiation; the collaborative work of each layer not only improves the gain, directivity, and stability of the antenna device but also facilitates mass production and miniaturization, making it suitable for highly integrated communication systems. In some possible embodiments, the waveguide can be made of wave-transparent materials, such as polypropylene, fiberglass, and alumina ceramic.

[0052] In some other possible embodiments, the protective component 5 may also be a cover covering the radiator 3, so that the radiator 3 and the protective component 5 are spaced apart. This application does not limit the specific structure of the protective component 5, and it can be selected according to actual needs such as process and cost.

[0053] like Figure 1 and Figure 2As shown, in some embodiments, the antenna device further includes a duplexer 6 and a working component 7; the duplexer 6 is connected to the isolation cover 2 and is signal-connected to the radiator 3; the main function of the duplexer 6 is to ensure that the transmitted and received signals of the radiator 3 do not interfere with each other. In some possible embodiments, the duplexer 6 isolates the transmitted and received frequency bands through a built-in filter structure, enabling the antenna device to simultaneously transmit and receive signals on the same radiator 3, thus improving the utilization efficiency of the radiator 3. Simultaneously, the duplexer 6 can effectively suppress interference of the transmitted signal to the receiver, protect the sensitive receiving circuit, and ensure the stability and signal quality of the communication system. In some possible embodiments, the duplexer 6 can be connected to the radio frequency component 4 and to the radiator 3, allowing the radiator 3 to transmit the received signal to the radio frequency component 4 via the duplexer 6.

[0054] For example, the duplexer 6 can be connected to the isolation cover 2 by bolts, or the duplexer 6 can be connected to the isolation cover 2 by adhesive. This application does not limit the specific connection method between the duplexer 6 and the isolation cover 2, and the choice can be made according to actual conditions such as process and cost. The duplexer 6 is disposed inside the accommodating cavity to prevent damage to the duplexer 6, thereby increasing the service life of the antenna device.

[0055] The working component 7 is disposed inside the accommodating cavity and connected to the radiator 3. The working component 7 is used to control the radiator 3 to generate or receive signals. In some possible embodiments, the working component 7 may include a baseband component 701, a power supply board, and an expansion component 702, etc. The main function of the baseband component 701 is to process raw digital signals: the baseband component 701 can encode, modulate, and perform digital-to-analog conversion on the information data to be transmitted, generate a low-frequency baseband signal, and send it to the radio frequency component 4 for up-conversion and amplification, and transmit it to the radiator 3 through the duplexer 6 so that the radiator 3 can transmit the signal; when the radiator 3 receives a signal, the received signal can be transmitted to the radio frequency component 4 through the duplexer 6, and the down-converted signal from the radio frequency component 4 is demodulated, decoded, and converted from analog to digital to restore the data that can be recognized by the device. The power supply board can be connected to an external power source so that the power supply board can supply power to the antenna device to maintain the operation of the antenna device. The expansion component 702 may also include components such as phase shifters, power dividers, and filters. This application does not limit the specific structure of the expansion component 702, and it can be selected according to the usage requirements of the antenna device.

[0056] The radio frequency (RF) component 4 is mounted on the working component 7, enabling the RF component 4 to transmit signals received by it to the working component 7. Exemplarily, the working component 7 can be fixed to the housing 1 by bolts or connecting adhesive, and the RF component 4 can be connected to the working component 7 by a cable. This application does not specifically limit the connection method between the working component 7 and the housing 1, or the connection method between the RF component 4 and the working component 7; the choice can be made based on the actual needs of the antenna device and cost considerations. In some possible embodiments, the processing device can be connected to the working component 7.

[0057] In some embodiments, the antenna device further includes a waveguide latch, which passes through the isolation cover 2 and connects to the duplexer 6 and the radiator 3 to enable signal transmission between the duplexer 6 and the radiator 3. The waveguide latch enables a stable mechanical connection and electrical contact between the duplexer 6 and the radiator 3. In some possible embodiments, the waveguide latch may contain connecting lines and connectors to ensure signal connection between the radiator 3 and the duplexer 6. The waveguide latch may include a first holding structure and a second holding structure, while a third holding structure is provided on the side of the radiator 3 near the isolation cover 2, and a fourth holding structure is provided on the duplexer 6. The first holding structure is connected to the third holding structure, and the second holding structure is connected to the fourth holding structure, thus achieving a stable mechanical connection between the waveguide latch, the duplexer 6, and the radiator 3. For example, the first and third holding structures, as well as the second and fourth holding structures, can be a combination of a card block and a card slot. Alternatively, they can be an interference fit between a hole and a shaft. This application does not limit the specific structure of the waveguide clip; it can be selected based on actual conditions such as cost and manufacturing process. In other possible embodiments, the radiator 3 and the radio frequency component 4 can be connected via a cable or metal conductor passing through the isolation cover 2, enabling signal exchange between the radiator 3 and the radio frequency component 4.

[0058] like Figure 1 As shown, in some embodiments, a plurality of heat dissipation protrusions 8 are provided on the side of the housing 1 away from the isolation cover 2. The function of the heat dissipation protrusions 8 is to increase the contact area between the housing 1 and the air, thereby increasing the heat dissipation area of ​​the housing 1 and thus increasing the heat dissipation capacity inside the accommodating cavity. This allows the working components 7, duplexer 6, and radio frequency components 4 inside the accommodating cavity to be effectively cooled, so that the antenna device can be maintained at a stable operating temperature. For example, the heat dissipation protrusions 8 can be multiple elongated rectangular protrusions, or they can be arc-shaped protrusions. This application does not limit the specific structure of the heat dissipation protrusions 8, and they can be selected according to the actual situation such as heat dissipation requirements and cost.

[0059] In some embodiments, the isolation cover 2 is a metal cover. The metal cover is a good conductor, effectively reflecting and absorbing electromagnetic waves, forming a Faraday cage effect, thereby blocking electromagnetic waves generated by the radiator 3 from interfering with the radio frequency component 4, ensuring stable signal transmission of the antenna device. In some possible embodiments, the metal cover can be an aluminum alloy cover; in other possible embodiments, the metal cover can be copper or a copper alloy. This application does not limit the specific material of the isolation cover 2; it can be selected according to actual needs such as cost and manufacturing process.

[0060] like Figure 1 As shown, in some embodiments, the antenna device further includes a sealing component 9, which is disposed between the isolation cover 2 and the housing 1 to ensure a sealed connection between the isolation cover 2 and the housing 1. The main function of the sealing component 9 is to achieve a sealed connection between the isolation cover 2 and the housing 1, so that when the antenna device is in an external environment, especially in extreme conditions, rainwater is prevented from entering the accommodating cavity through the connection between the housing 1 and the isolation cover 2, thereby preventing corrosion of the components inside the accommodating cavity from the external environment and effectively increasing the service life of the antenna device. Exemplarily, the sealing component 9 can be a rubber sealing ring or a sealing element. This application does not limit the specific structure of the sealing component 9, and it can be selected according to actual conditions such as process and cost.
