Description

Technical Field

[0001] This invention relates to the field of antenna structure technology, and more specifically, to a phased array antenna structure. Background Technology

[0002] With the trend towards lightweight active phased array radars and the high integration of transducer (TR) components, higher requirements have been placed on the size and weight of active phased array antennas, namely: miniaturization, light weight, and high reliability. Phased array antennas primarily amplify, radiate, and spatially synthesize the transmitted excitation signal. Based on the control commands of the beam controller, the antenna can scan the transmitted beam and radiate into a designated airspace. During reception, the antenna amplifies the target echo signal received by the array and synthesizes it into a summed signal. For a phased array antenna to function, it requires TR components, an antenna array, a summed network, a beam controller, and a power supply. Currently, the TR array, antenna array, and summed network are interleaved to form corresponding connectivity relationships. This interleaved arrangement makes maintenance very inconvenient, especially for the TR components.

[0003] In conclusion, how to effectively solve the problem of inconvenient maintenance of TR components is an urgent issue that needs to be addressed by those skilled in the art. Summary of the Invention

[0029] This invention discloses a phased array antenna structure to effectively solve the problem of inconvenient maintenance of TR components.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-7 , Figure 1 This is an exploded view of the phased array antenna structure provided in an embodiment of the present invention. Figure 2 This is a schematic diagram of the phased array antenna structure provided in an embodiment of the present invention; Figure 3 This is a schematic diagram of the rear structure of the antenna provided in an embodiment of the present invention; Figure 4 A schematic diagram of the front structure of the antenna provided in an embodiment of the present invention; Figure 5 This is a schematic diagram of the structure of the sum and difference component provided in an embodiment of the present invention; Figure 6 This is a schematic diagram of the structure of the TR component provided in an embodiment of the present invention; Figure 7 This is a schematic diagram of the structure of the wave-controlled power supply assembly provided in an embodiment of the present invention.

[0032] In some embodiments, a phased array antenna structure is provided, which mainly includes a beam control power supply component 3, a TR component 4, a sum and difference component 2 and an antenna 1, wherein the circuit connection relationship between the beam control power supply component 3, the TR component 4, the sum and difference component 2 and the antenna 1 can refer to the prior art.

[0033] TR component 4, also known as a transceiver component, is a type of antenna that can be detachably electrically connected to the beam control power supply component 3. It should be noted that a typical phased array antenna structure has multiple TR components 4, all of which can be detachably connected to the beam control power supply component 3 and the antenna 1. This can be done by connecting all or some of the TR components 4 to the beam control power supply component 3, but at least two TR components 4 must be detachably connected to the beam control power supply component 3. Detachable connection means that the connection between them can be broken, such as through a detachable connector, to facilitate disconnecting the connection between the TR component 4 and the beam control power supply component 3. This connection can be electrically conductive and / or photoelectrically conductive. It should also be noted that if the TR component 4 needs to be detached from other structures, then the corresponding connection between the TR component 4 and the corresponding structure must be detachable, such as the connection between the TR component 4 and the antenna 1, and the connection between the TR component 4 and the sum / difference component 2.

[0034] At least two TR components 4 have identical mounting structures to allow for interchangeable mounting positions. The degree of similarity in these mounting structures is determined by their interchangeability, enabling multiple TR components 4 to be installed interchangeably. That is, at least two TR components 4 can be interchanged to facilitate replacement and maintenance using a unified structure. It should be noted that among all TR components 4 detachably electrically connected to the wave controller power supply assembly 3, any two TR components 4 can be interchanged, multiple TR components 4 can be interchanged, or only two TR components 4 can be interchanged. For two TR components 4 that can be interchanged, the main mounting structure's positional relationship and shape are generally identical to allow for interchangeability; however, other structures can differ without affecting the interchangeability. Alternatively, the two TR components 4 can have completely identical structures, or some non-interfering structural differences can be avoided. It should be noted that the mounting structure here includes not only the connection structure but also key mating structures, such as the fit between holes and posts.

[0035] For the multiple TR components 4 that can interchange their installation positions, they are all located on the side of the sum and difference component 2 away from the antenna 1. This allows them to be positioned relative to the sum and difference component 2 and offset from the antenna 1, avoiding being sandwiched between the antenna 1 and the sum and difference component 2, thus facilitating maintenance. The aforementioned multiple TR components 4 that can interchange their installation positions do not necessarily refer to all TR components 4 capable of interchangeable installation positions; it can be some or all of all TR components 4 capable of interchangeable installation positions.

[0036] In the aforementioned phased array antenna structure, during use, some TR components 4 can be interchanged in their installation positions and installed on the side of the sum and difference components 2 away from the antenna 1. This eliminates the need to disassemble the antenna 1 and the sum and difference components 2, greatly facilitating the replacement of TR components 4. Furthermore, the interchangeable nature of multiple TR components 4 effectively reduces maintenance and replacement costs. In summary, this phased array antenna structure effectively solves the problem of inconvenient maintenance of TR components 4.

[0037] In some embodiments, the TR component 4 and the antenna 1 are connected via a first RF connector 6 that engages through a plug-in mechanism, with both ends of the first RF connector 6 fixed to the TR component 4 and the antenna 1, respectively. This allows for a direct plug-in connection between the TR component 4 and the antenna 1, avoiding the use of wire connections and resulting in a more compact structure.

[0038] Specifically, the first RF connector 6 can be an SMP-KK RF coaxial connector, which mainly includes two end interface sections and a middle KK connector. The two ends of the KK connector are respectively inserted and connected to the two end interface sections. The two end ports are respectively located on the TR component 4 and the antenna 1.

[0039] In some embodiments, the wave-controlled power supply component 3 and the TR component 4 can be connected via a low-frequency connector 5 that engages through a plug-in mechanism. The two ends of the low-frequency connector 5 are fixed to the wave-controlled power supply component 3 and the TR component 4, respectively, allowing direct plug-in connection between them without the need for cables or other wired connections. To facilitate the connection between the wave-controlled power supply component 3 and the TR component 4 via the low-frequency connector 5, a guide mechanism 9 can be provided between them. The guide mechanisms 9 can be arranged in a one-to-one correspondence with the number of low-frequency connectors 5, typically with guide mechanisms 9 on both sides of the low-frequency connector 5. The guide mechanism 9 mainly includes a guide hole and a guide post, with one guide hole and guide post located on the wave-controlled power supply component 3 and the other on the TR component 4.

[0040] Similarly, the TR component 4 and the sum / difference component 2 can be connected by a second RF connector 7, wherein the two ends of the second RF connector 7 are fixed on the TR component 4 and the sum / difference component 2 respectively, so that the sum / difference component 2 and the TR component 4 can be directly connected by plugging.

[0041] In the above structure, the components that need to be connected, such as the wave-controlled power supply assembly 3, the TR assembly 4, the sum and difference assembly 2, and the antenna 1, are all connected by plug-in connectors, such as the low-frequency connector 5, the first radio frequency connector 6, and the second radio frequency connector 7. This avoids the use of a wire structure, making the overall connection tighter and the overall structure more compact.

[0042] In some embodiments, the first RF connector 6 and the second RF connector 7 may have the same structure, such as both being SMP-KK RF coaxial connectors. Of course, the specific structure and size are not required to be the same.

[0043] In some embodiments, the TR component 4, the sum and difference component 2, and the antenna 1 are respectively fixedly mounted on the body of the wave-controlled power supply component 3 by a mechanical locking mechanism 8, so that the wave-controlled power supply component 3 serves as the mounting base, and the TR component 4, the sum and difference component 2, and the antenna 1 are all connected to the wave-controlled power supply component 3 to maintain a stable positional relationship.

[0044] TR component 4, sum and difference component 2 and antenna 1 can also be fixed to each other by mechanical locking mechanism 8 as needed.

[0045] The mechanical locking mechanism 8 includes, but is not limited to, elastic buckle mechanism, bolt mechanism, screw mechanism, etc., and of course, welding or other methods can also be used for fixing.

[0046] In some embodiments, the antenna 1 can be plate-shaped; and the wave control power supply assembly 3 can be plate-shaped, with the side of the wave control power supply assembly 3 near the antenna 1 in surface-to-surface thermal contact with the corresponding side of the antenna 1, so that heat can be dissipated through the antenna 1.

[0047] In some embodiments, the sum and difference component 2 can be plate-shaped, with the side of the sum and difference component 2 closest to the antenna 1 in surface-to-surface thermal contact with the corresponding side of the antenna 1, so that the sum and difference component 2 can effectively transfer heat to the antenna 1; the TR component 4 is plate-shaped, with the side of the TR component 4 closest to the sum and difference component 2 in direct or indirect surface-to-surface thermal contact with the corresponding side of the sum and difference component 2, so that the TR component 4 can better transfer heat to the sum and difference component 2. It should be noted that surface-to-surface thermal contact can be direct or indirect. Indirect contact can be achieved by transferring heat between one or more intermediate plates. For example, if the surfaces of the former and the latter are in indirect surface-to-surface thermal contact through intermediate plates, then one side of the intermediate plate is in direct surface-to-surface thermal contact with the former surface, and the other side of the intermediate plate is in direct surface-to-surface thermal contact with the latter surface, thus achieving large-area thermal contact as well. In the indirect surface-to-surface thermal contact, as in the following embodiment, the side of the TR component 4 near the sum and difference component 2 and the corresponding side of the sum and difference component 2 indirectly transfer heat through the plate-shaped connector 32.

[0048] In the above embodiments, the sum and difference components 2 generally do not generate heat. The heat is mainly generated by the wave control power supply component 3 and the TR component 4. The antenna 1 is generally located on the outside, so heat can be dissipated through the antenna 1. Because the antenna 1 has a large plate-shaped structure, it can quickly dissipate heat to the outside to ensure heat dissipation efficiency.

[0049] It should be noted that "plate-like" mainly refers to an overall plate-like structure, in which at least one side of the plate is a heat-conducting surface.

[0050] In the above structure, for better heat conduction, the outer shell and / or substrate of the sum and difference components 2 can be made of materials with good thermal conductivity, such as metals with good thermal conductivity. Correspondingly, one side plate of the antenna 1 absorbs heat and needs to dissipate it externally, so the outer shell and / or substrate of the antenna 1 can also be made of materials with good thermal conductivity, such as metals with good thermal conductivity. Since both the wave control power supply component 3 and the TR component 4 need to dissipate heat externally, they must each have a structure on their outer side capable of dissipating the heat they generate. This structure can be their respective outer shell and / or substrate, or it can be only a part of the above structure, not necessarily all of it.

[0051] In some embodiments, the beam control power supply assembly 3 may include a plate-shaped main body 31 and a connector 32 disposed on one side of the main body 31. The main body 31 contains a beam control power supply circuit structure, and the main body 31 is in surface-to-surface thermal contact with the antenna 1 to directly transfer heat to the antenna 1. The connector 32 is disposed between the TR component 4 and the sum / difference component 2, wherein the TR component 4 and the sum / difference component 2 are respectively fixedly connected to the connector 32. The connector 32 facilitates the connection of the TR component 4 and the sum / difference component 2 to the beam control power supply assembly 3. Specific connection methods can be configured as needed, generally using screws or snap-fit ​​connections. Typically, a portion of the screws pass sequentially through the connector 32 and the TR component 4, and another portion of the screws pass sequentially through the connector 32 and the sum / difference component 2; alternatively, at least a portion of the screws may pass sequentially through the connector 32, the TR component 4, and the sum / difference component 2. Specifically, at least one first connecting screw 81 connects the main body 31 to the antenna 1 along the plate thickness direction, and at least a plurality of second connecting screws 82 connect the TR component 4, the connector 32, the sum and difference component 2, and the antenna 1 in sequence along the plate thickness direction. Specifically, the TR component 4 can be fixed to the connector 32 by some second connecting screws 82, and the connector 32, the sum and difference component 2, and the antenna 1 can also be connected by some second connecting screws 82.

[0052] In some embodiments, the four corners of TR component 4 and sum / difference component 2 are connected to connector 32 to ensure fixed strength; of course, the connection can also be partial.

[0053] In some embodiments, considering that all four corners are connected to the connector 32, the connector 32 may interfere with the thermal contact between the sum and difference component 2 and the TR component 4. Holes can be made between the sum and difference component 2 and the TR component 4 to facilitate direct contact between them. If the hole is too large, it will affect the strength of the connector 32; if the hole is too small, it will affect the thermal conductivity between the TR component 4 and the sum and difference component 2.

[0054] In some embodiments, for ease of explanation, the side-by-side direction of the main body 31 and the TR component 4 is left-right, and the side-by-side direction of the antenna 1 and the main body 31 is inward-outward, with the main body 31 disposed inside the antenna 1. Then, from the inside out, the TR component 4, the connector 32, and the sum-difference component 2 are arranged sequentially. The connector 32 is disposed on one side of the main body 31 in the left-right direction, preferably in the middle of the main body 31 in the inward-outward direction, and preferably the inner side of the main body 31 and the inner side of the TR component 4 are aligned in the inward-outward direction to make the overall structure more compact.

[0055] In some embodiments, the connector 32 can be a heat-conducting plate, located between the TR component 4 and the sum-difference component 2 for heat transfer, avoiding the need for holes, thus ensuring the strength of the connector 32 while also ensuring thermal conductivity.

[0056] In some embodiments, for ease of connection, the connecting member between the TR component 4 and the antenna 1 can pass through the connector 32 and the sum / difference component 2. This connecting member is like the first RF connector 6 described above. Preferably, the corresponding through-hole on the connector 32 is clearance-fitted with the first RF connector 6, but an interference fit is also possible. Specifically, the KK connector can pass through the corresponding through-hole on the connector 32 and be fitted together. The connecting member between the TR component 4 and the sum / difference component 2 passes through the connector 32. This connecting member is like the second RF connector 7 described above. Preferably, the corresponding through-hole on the connector 32 is clearance-fitted with the second RF connector 7, but an interference fit is also possible.

[0057] In some embodiments, generally, the beam control power supply assembly 3, the TR assembly 4, the sum and difference assembly 2, and the antenna 1 are aligned in the same thickness direction. Multiple TR assemblies 4 are arranged side-by-side along the longitudinal direction, which is perpendicular to both the aforementioned inner / outer direction and the aforementioned left / right direction. Each of the TR assemblies 4 is plugged into and connected to the main body 31 in the parallel direction.

[0058] In some embodiments, a phased array antenna structure is provided, which may be the phased array antenna structure in any of the above embodiments, or a watt-type one-dimensional phased array antenna structure.

[0059] Antenna 1 is used to transmit and / or receive electromagnetic waves. Antenna 1 can be a waveguide slot antenna, which can also be called a waveguide slot array antenna 1. The waveguide slot antenna 1 is an antenna 1 that generates electromagnetic wave radiation by cutting narrow slots in the waveguide wall according to a certain pattern. Of course, antenna 1 can also be other types of antenna 1.

[0060] Meanwhile, antenna 1 is equipped with a mechanical mounting interface corresponding to the wave-controlled power supply assembly 3, as well as mechanical mounting interfaces corresponding to the frequency trace assembly and TR assembly 4, which are separate from the phased array antenna 1. Antenna 1 is a metal component, while the TR assembly 4 and wave-controlled power supply assembly 3 are heat dissipation components.

[0061] The sum and difference component 2 is mainly responsible for the synthesis or distribution of radio frequency signals. The sum and difference component 2 adopts a chip layout, with six RF split ports on one end face and three combiner ports on the side. All interfaces are SMP-J type, which is the end interface section of the SMP-KK RF coaxial connector.

[0062] The wave controller power supply assembly 3 is used to power the corresponding equipment. It integrates wave controller and power supply design, supplying power to six TR components 4 via six low-frequency connectors 5, and handling command issuance and data reception for the TR components 4. The wave controller power supply assembly 3 adopts a T-shaped structure and is integrally machined. One side of the assembly is the main body of the wave controller power supply, and the other side is a pure mounting part, namely the connector 32. The TR components 4 are mounted on the front of the connector 32, and the sum and difference components 2 are mounted on the back. On one side of the main body of the wave controller power supply, there is an external connector 11 for connecting to the signal interface and a clock signal interface 12 on one side of the cavity; on the opposite side of the cavity, there is a power input interface 13 and a power output interface 14.

[0063] TR component 4, also known as a T / R component, is the part between the radio frequency (RF) and antenna 1 in a wireless transceiver system. Specifically, TR component 4 connects to antenna 1 at one end and the intermediate frequency (IF) processing unit at the other, forming a wireless transceiver system. TR component 4 is an eight-channel TR component, with RF input and output ports designed on the same side. Both interfaces use SMP-J, namely the end interfaces of the first RF connector 6 and the second RF connector 7. A low-frequency connector 5 is arranged on one side of TR component 4. The low-frequency connector 5 is designed with positioning pins to facilitate mating assembly between TR component 4 and the waveguide power supply component 3. TR component 4 adopts a universal and standardized design for easy installation and maintenance.

[0064] Among them, the wave control power supply component 3, the TR component 4, and the sum and difference component 2 are active parts. During assembly, the housing of the wave control power supply component 3 is used as the installation reference. The TR component 4 is positioned and installed by the positioning pin on the low frequency connector 5 and the plug of the low frequency connector 5 on the wave control power supply body.

[0065] There are six TR components 4, and at least two TR components 4 can be installed in interchangeable positions. Generally, any two of the six TR components 4 can be interchanged, can be disassembled and installed individually, and are easy to maintain.

[0066] The sum and difference component 2 is connected to the six TR components 4 via SMP-KK.

[0067] After the active components are installed, the forty-eight RF interfaces on TR component 4 are connected to antenna 1 using SMP-KK plug-in. Antenna 1 is designed with KK head guide holes to facilitate accurate plug-in of the forty-eight KK interfaces.

[0068] All low-frequency control signals, power supply, and radio frequency signals between components within the aforementioned phased array antenna structure are connected via connectors, eliminating the need for cables. This reduces the overall size of the phased array antenna structure and eliminates the need to consider cable routing space, making cable-free connections safer and more reliable.

[0069] The phased array antenna structure adopts a tile-type layout, which is compact and small in size. TR module 4 adopts a standardized and universal design, which facilitates maintenance.

[0070] Antenna 1 can be a machined aluminum alloy component, serving as a heat dissipation component for TR assembly 4 and wave control power supply assembly 3, eliminating the need for a separate heat dissipation structure, thus further reducing the overall size and weight of phased array antenna 1.

[0071] The wave-controlled power supply assembly 3 is manufactured as a single piece with a T-shaped layout. It serves as a mounting platform for the TR assembly 4 and the sum / difference assembly 2, reducing installation errors. It also shortens the heat transfer path and lowers thermal resistance. The wave controller and power supply within the wave-controlled power supply assembly 3 are integrated into a single PCB, handling both control and power supply functions. Compared to using separate wave controllers and power supplies, the overall size is significantly reduced, and internal wiring is simpler.

[0072] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0073] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
