[0022] Example

[0023] like figure 1 , figure 2 As shown, the present invention sets the axis of the first output rectangular waveguide 2, the axis of the input rectangular waveguide 1, and the axis of the second output rectangular waveguide 3 into a structure in which the axes of the structures are perpendicular to each other in a three-dimensional space that is perpendicular to each other. The problem of good balance, and the internal matching structure 4 can effectively ensure the isolation problem, and in order to ensure the optimization of the effect, the matching structure 4 is processed by one-time milling. Therefore, a compact power splitter includes an input rectangular waveguide 1 and a second output rectangular waveguide 3 mainly composed of an output first output rectangular waveguide 2, and an input rectangular waveguide 1 and a second output rectangular waveguide 3 connected with the first output rectangular waveguide 2, the output first output rectangular waveguide A matching structure 4 is arranged inside the waveguide 2 . The matching structure 4 is composed of at least three columnar bodies whose axes are parallel and connected in sequence. The matching structure 4 partially extends into the interior of the input rectangular waveguide 1 . The end of the second output rectangular waveguide 3 away from the matching structure 4 is bent 90 degrees around the axis of the first output waveguide 2, which reduces the volume of the magic T power splitter and makes the structure more compact, and the second output rectangular waveguide 3 is bent Parts are provided with absorbing materials 7 .

[0024] The axes of the first output rectangular waveguide 2 , the input rectangular waveguide 1 , and the second output rectangular waveguide 3 are perpendicular to each other, and the axis of the second output rectangular waveguide 3 is parallel to the axis of the columnar body.

[0025] In order to make the second output port 5 and the third output port 6 complete the same-amplitude and in-phase action. The first output rectangular waveguide 2 further includes a left-turned output rectangular waveguide and a right-turned output rectangular wave disposed at both ends of the first output rectangular waveguide 2 . A second output port 5 is provided at one end of the left-turned output rectangular waveguide away from the matching structure 4; A third output port 6 is provided at one end of the right-turned output rectangular waveguide away from the matching structure 4; and the part of the right-turned output rectangular waveguide away from the matching structure 4 is bent 90 degrees clockwise in the horizontal plane.

[0026] All the columns forming the matching structure 4 are symmetrical with respect to the axis of the input rectangular waveguide 1, and the heights of all columns along the axis of the input rectangular waveguide 1 decrease from the first output waveguide 2 to the input rectangular waveguide 1; The width in the axial direction of the waveguide 2 increases along the direction from the input rectangular waveguide 1 to the first output waveguide 2 .

[0027] The material of the matching structure 3 is metal.

[0028] When the present invention works, when the signal is input from the port of the input rectangular waveguide 1, the second output port 5 and the third output port 6 complete the output of equal amplitude and in-phase, and some matching elements are placed in the magic T to make it reflect The reflections generated by the discontinuity of the magic T match the ports. Here, the part of the left-turned output rectangular waveguide away from the isolated output rectangular waveguide is bent 90 degrees in the counterclockwise direction in the horizontal plane, and the part of the right-turned output rectangular waveguide away from the isolated output rectangular waveguide is bent 90 degrees in the clockwise direction in the horizontal plane, The signals are output in phase at the second output port and the third output port. The end of the second output rectangular waveguide 3 away from the matching structure 4 is bent 90 degrees around the axis of the first output waveguide 2 , which reduces the volume of the magic T power splitter and makes the structure more compact. The bent portion of the second output rectangular waveguide is provided with a wave absorbing material, so that the electromagnetic waves entering the second output rectangular waveguide are completely absorbed.
