High-density multichannel waveguide network

[0024] The existing transitional waveguide network usually consists of only a few waveguide links, and the arrangement space is relatively large, the spatial layout is relatively simple, and the waveguide orientation is relatively simple. In this way, in actual use, if a waveguide is damaged and needs to be replaced, it is difficult. Moreover, the large occupied space also severely limits the application occasions. How to deploy multiple waveguide links in a small space, and it is convenient and quick to replace the waveguide links when a fault occurs, which has become a problem to be solved.

[0025] Aiming at the deficiencies of existing technologies, such as figure 1 As shown, the present invention provides a high-density multi-channel waveguide network, including: upper flange 1, lower flange 2, top-level waveguide link 3, middle-level waveguide link 4, and bottom-level waveguide link 5; 1 and the lower flange 2 are both circular and the diameter of the upper flange 1 is smaller than the diameter of the lower flange 2;

[0026] Such as figure 2 , 3 As shown in, 4, 7, 8, and 9, the top-level waveguide link 3 includes 128 90°-bent waveguides, the middle-level waveguide link 4 includes 128 multi-bend shaped waveguides, and the bottom-level waveguide link 5 includes 128 90°-bend waveguides. And 128 transition waveguides, the output end of each curved waveguide is connected to a transition waveguide; the 90° curved waveguide in the top-level waveguide link (3) is E-plane or H-plane, and the bottom-level waveguide link (5) 90° curved waveguide is also E-face or H-face

[0027] The input port of the 90° bent waveguide in the top-level waveguide link 3 is connected to the input waveguide port on the upper flange 1, and the output port of the 90° bent waveguide in the top-level waveguide link 3 is connected to the multi-bend profile of the middle-level waveguide link 4. The input port of the waveguide is connected, the output port of the multi-bend profiled waveguide is connected to the input port of the 90°-bending waveguide of the bottom waveguide link 5, and the output port of the 90°-bending waveguide of the bottom waveguide link 5 is connected to the lower flange through the transition waveguide The output waveguide port on 2 forms 128 waveguide channels, such as Figure 5 As shown, the 128 waveguide channels are all located inside the outer envelope of the multi-channel transition waveguide network; the outer envelope refers to the outer surface of the truncated cone formed by connecting the edges of the upper flange 1 and the lower flange 2 together, The input waveguide port and the output waveguide port are both rectangular, and the distance between the upper flange 1 and the lower flange 2 is 164 mm;

[0028] Such as Image 6 As shown, the input waveguide ports on the upper flange 1 are arranged in 13 rows, rows 1 to 6 and rows 8 to 13 are symmetrically distributed with respect to row 7, and rows 1 to 6 include 7 and 8 respectively , 9, 10, 11, 12 input waveguide ports, the distance between two adjacent input waveguide ports in each row is 17mm, the distance between two adjacent rows is 14.72mm, the seventh row includes 12 There are two input waveguide ports, the center point of the seventh row is the center of the upper flange 1, the input waveguide ports on the seventh row are symmetrically distributed about the center point, and the 13 rows of input waveguide ports on the upper flange 1 are arranged in a regular hexagon The shape, the center of the regular hexagon is the center of the upper flange 1.

[0029] The distance between two adjacent input waveguide ports in each row refers to: the distance between the center of the input waveguide port and the center of the adjacent input waveguide port; the distance between two adjacent rows refers to: all inputs in a row The distance between the straight line connecting the center points of the waveguide ports and the straight line connecting the center points of the adjacent rows of input waveguide ports.

[0030] The size of the input waveguide port on the upper flange (1) is 6.4 mm×2.85 mm, and the size of the output waveguide port on the lower flange (2) is 7.112 mm×3.556 mm. The diameter of the upper flange (1) is 365mm, and the diameter of the lower flange (2) is 480mm.

[0031] The 128-channel transition waveguide proposed by the present invention realizes compact arrangement in a limited space through a reasonable spatial layout, thereby realizing high density, miniaturization and light weight of the entire waveguide network. At the same time, since the input aperture and output aperture of each waveguide of the waveguide network are inconsistent, the present invention also designs a transitional conversion waveguide for conversion to realize the function of the transitional waveguide network, so as to adapt to more applications.
