Embodiment 1

[0074] Such as Figure 1a ~ Figure 1e shown.

[0075] A rectangular waveguide four-way coaxial power splitter based on metal ridges includes an input transmission line 2 and four output transmission lines 4, and the axes of the input transmission lines 2 and output transmission lines 4 are along the Z direction.

[0076] The input transmission line 2 is a double ridge waveguide.

[0077] The output transmission line 4 is a microstrip line.

[0078] An electromagnetic wave channel 3 is arranged between the input transmission line 2 and the output transmission line 4 , and the electromagnetic wave channel 3 communicates with the input transmission line 2 through one end surface thereof.

[0079] The four-way power splitter is provided with four waveguides 5 and a metal ridge component C along the Z direction in each waveguide 5 between the electromagnetic wave channel 3 and the output transmission line 4 .

[0080] Each metal ridge assembly C includes two metal ridges C51 con...

Embodiment 2

[0090] Such as Figure 2a~2c shown.

[0091] Compared with the implementation example 1, the main difference between this implementation example is that no electromagnetic wave channel or microstrip transmission line is provided. The input transmission line is a rectangular waveguide. The four output transmission lines are ridge waveguides.

Embodiment 3

[0093] Such as Figure 3a~3d shown.

[0094] Compared with the implementation example 1, the main difference between this implementation example is that the input transmission line is a rectangular waveguide, and no electromagnetic channel 3 is provided.

Abstract

The invention discloses a rectangular waveguide four-path coaxial power divider based on a metal ridge. The rectangular waveguide four-path coaxial power divider comprises an input transmission line and four output transmission lines, an electromagnetic wave channel and the metal ridge; the input transmission line is the rectangular waveguide, at least two waveguides and at least four metal ridgemodules C along a Z direction in the waveguides are arranged between the input transmission line and the output transmission lines; each metal ridge module C comprises at least two metal ridges C mutually communicated along the Z direction, each metal ridge C in each metal ridge module C is connected with the inner wall of the located waveguide only at the same direction; and the output transmission lines are coaxial lines. The outstand feature of the rectangular waveguide four-path coaxial power divider is that the compact bandwidth matching to four transmission lines from one transmission line can be realized in short distance. The rectangular waveguide four-path coaxial power divider disclosed by the invention is mainly used for various communication and radar systems in microwave, millimeter wave and terahertz wavebands.
