Description

Technical Field

[0001] This invention belongs to the field of antenna structure design technology, and in particular relates to a high-power 1 to 64 rectangular power divider open waveguide array antenna structure. Background Technology

[0002] High-power microwaves refer to strong electromagnetic radiation with a frequency range of 0.3 GHz to 300 GHz and an average power of not less than 1 MW. They have important applications in fields such as communications, radar electronic warfare, and nuclear fusion heating. Due to their high power, few antennas and feed connectors can withstand them. However, open waveguide antennas have excellent electrical properties such as high power capacity, low loss, and stable radiation performance. They are a very common and important antenna type in high-power microwave systems and are widely used.

[0003] To improve the power withstand capability inside the open waveguide antenna, the antenna cavity is often filled with sulfur hexafluoride (SF6) gas. Studies have shown that when the sulfur hexafluoride gas pressure is 1 standard atmosphere, its breakdown field strength is 7 to 8 × 10⁶ V / m, and the corresponding power withstand capability can be increased by 5 to 7 times. Therefore, the open waveguide antenna is required to be airtight.

[0004] Traditional open-aperture waveguide antennas struggle to achieve rectangular power divider arrays with multiple divisions (one-to-many). They often rely on a combination of multiple horizontal and vertical waveguide power distribution networks, resulting in complex structures, large size and weight, complicated assembly, and difficult sealing, making them unsuitable for high-power applications. While 3D printing technology can theoretically solve the manufacturing challenges of the complex structure of open-aperture waveguide antennas, it doesn't significantly improve the surface roughness and sealing of the waveguide, making it prone to arcing and even electric field breakdown. Therefore, it still falls short of meeting the requirements for open-aperture waveguide antennas in high-power microwave systems. Summary of the Invention

[0005] The purpose of this invention is to address the current challenges of high-power microwave systems with multi-aperture waveguide array antennas. This invention proposes a high-power 1-to-64 rectangular power divider waveguide array antenna structure. The structure is designed using a computer, and layered design, processing, and assembly are carried out along the waveguide axis. Positioning pins and sealing rings are used to achieve positioning and sealing between layers. This solves the problems of complex structure, difficult processing, and difficult sealing of multi-aperture waveguide array antennas. It has the characteristics of low profile, small size, and light weight, and meets the requirements of being able to withstand electromagnetic waves with an average power of not less than 1 MW.

[0006] To achieve the object of the present invention, the present invention discloses a high-power one-to-sixty-four rectangular power-dividing open waveguide array antenna structure, which is stratified along the antenna axis from input to output; the antenna divides one input port into sixty-four output ports, and is divided into seven parts along the direction from input to output by using the mutation cross-sections of one-to-two, two-to-four, four-to-eight, eight-to-sixteen, and sixteen-to-sixty-four in the internal cavity channel of the antenna as the parting surfaces in sequence, namely antenna layer one, antenna layer two, antenna layer three, antenna layer four, antenna layer five, antenna layer six, and antenna layer seven; taking antenna layer four as the assembly reference, the front and back sides of the antenna in the axial direction are assembled layer by layer to achieve the one-to-sixty-four rectangular array power division of the open waveguide antenna; the antenna structure is designed with tuning screws, which can adjust the impedance and standing wave of the antenna.

[0007] Further, antenna layer one serves as the input of the entire open waveguide array antenna, and its interface is a square choke flange of a standard BJ100 waveguide.

[0008] Further, a conical surface and tuning screws for adjusting the standing wave and impedance of the entire open waveguide array antenna are designed on antenna layer two, and precise positioning and cavity sealing are achieved with antenna layer one through positioning pins and sealing rings, and at the same time, the power division of the waveguide cavity from one to two is realized.

[0009] Further, antenna layer three serves as the transition between antenna layer two and antenna layer four, and precise positioning and cavity sealing are achieved through positioning pins and sealing rings; at the same time, it cooperates with antenna layer two and antenna layer four respectively to realize the power division of the waveguide cavity from two to four and four to eight.

[0010] Further, antenna layer four serves as the installation foundation and sealing transition part of the entire open waveguide antenna, and a waveguide sealing window is embedded and welded on it, ensuring the cavity sealing between antenna layer one and antenna layer four.

[0011] Further, through the precise positioning of pins, antenna layer five cooperates with antenna layer six to achieve the power division of the waveguide cavity from eight to sixteen.

[0012] Further, antenna layer six serves as the transition part between antenna layer five and antenna layer seven, strengthening the structure of antenna layer seven while realizing the power division of the waveguide cavity from eight to sixteen, and ensuring the accuracy of the internal cavity shape of the entire open waveguide array antenna.

[0013] Further, antenna layer seven serves as the output end of the entire open waveguide antenna, and realizes the power division of the waveguide cavity from sixteen to sixty-four through a "field" - shaped structure. Finally, the waveguide openings of standard BJ100 with a spacing of 23.86mm x 11.16mm and an 8×8 rectangular arrangement are used as the output of the entire open waveguide array antenna.

[0014] Compared with the prior art, the significant progress of the present invention is that the antenna structure of the present invention adopts the technical means of layered design, processing and assembly. The positioning and sealing between layers are achieved by positioning pins and sealing rings, which solves the problems of complex structure, difficult processing and difficult sealing of 1 to 64 open waveguide array antenna. It cleverly realizes the adjustment of impedance and standing wave, which not only ensures the surface quality, sealing performance and electrical performance of the inner surface of the cavity, but also saves costs, reduces difficulty and reduces weight.

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.

[0028] A high-power 1-to-64 rectangular power divider open waveguide array antenna structure is disclosed, with the antenna layered along the antenna axis from input to output. The antenna divides the power from one input port into sixty-four output ports. The antenna is sequentially divided into seven parts along the input-to-output direction using abrupt cross-sections of the internal cavity channel: 1-to-2, 2-to-4, 4-to-8, 8-to-16, and 16-to-64. These parts are designated as antenna layer 1, layer 2, layer 3, layer 4, layer 5, layer 6, and layer 7. Using layer 4 as the assembly reference, the antenna is assembled layer by layer along both sides of the axial direction to achieve a 1-to-64 rectangular array power divider for the open waveguide antenna. The antenna structure includes 2-3 tuning screws to adjust the antenna impedance and standing wave ratio.

[0036] Embodiment

[0037] Please refer to Figures 1 to 9This invention discloses a high-power 1 / 64 rectangular power divider open-ended waveguide array antenna structure. The antenna is layered along the input-to-output antenna axis. The antenna divides power from one input port to sixty-four output ports. The antenna is sequentially divided into seven parts along the input-to-output direction using abrupt cross-sections of the internal cavity channel: 1 / 2, 2 / 4, 4 / 8, 8 / 16, and 16 / 64. These are antenna layer 1, antenna layer 2, antenna layer 3, antenna layer 4, antenna layer 5, antenna layer 6, and antenna layer 7. Using antenna layer 4 as the assembly reference, the antenna is assembled layer by layer along both sides of the axial direction to achieve a 1 / 64 rectangular array power divider for the open-ended waveguide antenna. Tuning screws 2-3 are designed in antenna layer 2 to adjust the impedance and standing wave ratio of the entire open-ended waveguide array antenna.

[0038] Antenna layer 1-1 is the input terminal of the entire open waveguide array antenna (the interface of input terminal 1-1-1 is a standard BJ100 waveguide square choke flange). It specifically consists of antenna layer 1 housing 1-1, O-ring 1-2, positioning pin 8, fastening screw assembly 9, and fastening screw assembly 2 10. Antenna layer 1 housing 1-1 is the main component, directly machined from aluminum profiles, with maximum dimensions of 69mm (length) × 60mm (width) × 20.6mm (thickness). It ensures a surface roughness of 3.2μm and a flatness of 0.05mm for input terminal 1-1-1 and output terminal 1-1-2, while also achieving a surface roughness of 1.6μm for the wall surface of the first internal cavity 1-1-3. Positioning pins 8 are diagonally distributed and mate with pin holes on antenna layer 2 to achieve alignment between cavity interfaces; O-ring 1-2 is installed in the sealing groove of output end 1-1-2 and is reliably sealed by fastening screw assembly 9 and fastening screw assembly 10, which are pressed together with the first sealing end face 2-1-1 of antenna layer 2. Fastening screw assembly 10 passes through antenna layer 2 and mates with threaded holes on antenna layer 2 3.

[0039] The antenna layer 2 consists of an antenna layer 2 housing 2-1, an O-ring 2-2, a tuning screw 2-3, locating pins 8, and a fastening screw assembly 9. The antenna layer 2 housing 2-1 is the main component, with dimensions of 97mm (length) × 60mm (width) × 23.4mm (thickness). It is directly machined from aluminum profiles, ensuring a surface roughness of 3.2μm and a flatness of 0.05mm for the first sealing end face 2-1-1 and the second sealing end face 2-1-2, while also achieving a surface roughness of 1.6μm for the wall surface of the second internal cavity 2-1-3. The locating pins 8 are diagonally distributed and align with the antenna layer 3 to achieve alignment between the cavity interfaces. The O-ring 2-2 is installed in the sealing groove of the second sealing end face 2-1-2 and is reliably sealed by pressing it against the third sealing end face 3-1-1 of the antenna layer 3 using the fastening screw assembly 9. The first sealing end face 2-1-1 has a local conical protrusion, which, together with the tuning screw 2-3, allows for adjustment of the impedance and standing wave ratio of the open-aperture waveguide array antenna. The tuning screw 2-3 adopts a pin screw structure, with a cylindrical fit at the top, a threaded middle section, and a circumferential array hole at the tail. The axial adjustment of the tuning screw 2-3 can be achieved using an Allen wrench through the weight reduction slot space of antenna layer 2.

[0040] The antenna layer 3 consists of an antenna layer 3 housing 3-1, an O-ring 3-2, locating pins 8, and a fastening screw assembly 9. The antenna layer 3 housing 3-1 is the main component, with external dimensions of 148mm (length) × 110mm (width) × 26mm (thickness). It is directly machined from aluminum profiles, ensuring a surface roughness of 3.2μm and a flatness of 0.05mm for the third sealing end face 3-1-1 and the fourth sealing end face 3-1-2, while also achieving a surface roughness of 1.6μm for the wall surface of the third internal cavity 3-1-3. The locating pins 8 are diagonally distributed and mate with the antenna layer 4 to align the cavity interfaces. The O-ring 3-2 is installed in the sealing groove of the fourth sealing end face 3-1-2 and is securely sealed by the fastening screw assembly 9 with the fifth sealing end face 4-1-1 of the antenna layer 4. The third sealing end face 3-1-1 has a rectangular protrusion in some areas, which is embedded and cooperates with the second sealing end face 2-1-2 of the antenna layer 2 to realize the two-to-four power division of the waveguide cavity.

[0041] The antenna layer 4, serving as the mounting base and sealing transition component for the entire open waveguide antenna, has main dimensions of 148mm (length) × 110mm (width) × 20mm (thickness). It primarily consists of the antenna layer 4 housing 4-1 and the sealing window 4-2. The sealing window 4-2 is soldered to the antenna layer 4 housing 4-1, and then machined to ensure the required roughness and flatness of the fifth sealing end face 4-1-1 and the sixth sealing end face 4-1-2. The sealing window 4-2 comprises the sealing window bottom shell 4-2-1, the sealing window cover plate 4-2-2, and the sapphire plate 4-2-3, all soldered together. The fifth sealing end face 4-1-1 and the sixth sealing end face 4-1-2 are designed with threaded holes and positioning pin holes, which can be used for the installation and fixation of antenna layer 3 and antenna layer 5 and ensure the alignment of the antenna cavity; among them, the fifth sealing end face 4-1-1 has a rectangular protrusion in part, which is fitted and cooperates with the fourth sealing end face 3-1-2 of antenna layer 3 to realize the four-to-eight power division of the waveguide cavity.

[0042] Antenna layer 5 consists of antenna layer 5 housing 5-1, positioning pin 8, and fastening screw assembly 9. It is precisely positioned and installed on the eighth sealing end face 5-1-2 of antenna layer 5 using positioning pin 8, and the screw assembly 9 ensures a tight fit between the seventh sealing end face 5-1-1 and the sixth sealing end face 4-1-2. The main body of antenna layer 5 housing 5-1 has external dimensions of 190mm (length) × 110mm (width) × 23mm (thickness), and is directly machined from aluminum profiles. This ensures that the roughness of the seventh sealing end face 5-1-1 and the eighth sealing end face 5-1-2 is 3.2μm and the flatness is 0.05mm, while also achieving the 1.6μm roughness requirement for the wall surface of the fifth internal cavity 5-1-3. The eighth sealing end face 5-1-2, in conjunction with the tenth sealing end face 6-1-2 of antenna layer 6, realizes the eight-division sixteen-power division of the waveguide cavity.

[0043] Antenna layer 6 consists of antenna layer 6 housing 6-1, positioning pin 8, and fastening screw assembly 9. It is precisely positioned and installed on the eighth sealing end face 5-1-2 of antenna layer 5 using the positioning pin 8, and the screw assembly 9 ensures a tight fit between the ninth sealing end face 6-1-1 and the eighth sealing end face 5-1-2. The main body of antenna layer 6 housing 6-1 has external dimensions of 210mm (length) × 110mm (width) × 20mm (thickness), and is directly machined from aluminum profile. This ensures the sealing requirements of a roughness of 3.2μm and a flatness of 0.05mm for the ninth sealing end face 6-1-1 and the tenth sealing end face 6-1-2, while also achieving a roughness requirement of 1.6μm for the wall surface of the sixth internal cavity 6-1-3. To enhance the rigidity of antenna layer 7 and the accuracy of the entire open waveguide antenna cavity, an additional fitting groove 6-1-4 is designed.

[0044] The antenna layer seven 7 serves as the output end of the entire open waveguide antenna. Through the "field" - shaped structure, a power division of the waveguide cavity into sixty - four parts out of sixteen is achieved. Finally, the waveguide openings of the standard BJ100 with a spacing of 23.86 mm x 11.16 mm and an 8×8 rectangular arrangement are used as the output of the entire array antenna, which consists of the antenna layer seven housing 7 - 1, the positioning pin 8, and the fastening screw assembly one 9. The main external dimensions of the antenna layer seven housing 7 - 1 are 210 mm (length) × 110 mm (width) × 37 mm (thickness). It is directly processed from aluminum profiles, which can ensure the roughness of 3.2 μm and flatness of 0.05 mm for the eleventh sealing end face 7 - 1 - 1 and the twelfth sealing end face 7 - 1 - 2 to meet the sealing requirements, and at the same time achieve the roughness requirement of 1.6 μm for the wall surface of the seventh internal cavity 7 - 1 - 3. The antenna layer seven housing 7 - 1 is precisely positioned and installed on the tenth sealing end face 6 - 1 - 2 of the antenna layer six 6 through the positioning pin 8, and the close fit between the eleventh sealing end face 7 - 1 - 1 and the tenth sealing end face 6 - 1 - 2 is ensured by the screw assembly one 9.
