Embodiment 1

[0067] Such as Figure 1a ~ Figure 1e shown.

[0068] A compact double-ridge rectangular waveguide four-way microstrip power divider 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.

[0069] The input transmission line 2 is a double ridge waveguide.

[0070] The output transmission line 4 is a microstrip line.

[0071] An electromagnetic wave channel 3 is provided 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.

[0072] 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 .

[0073] Each metal ridge component C includes two metal ridges C51 c...

Embodiment 2

[0083] Such as Figure 2a~2d shown.

[0084] Compared with the implementation example 1, the main difference between this implementation example is that no electromagnetic channel 3 is provided.

Embodiment 3

[0086] Such as Figure 3a~3e shown.

[0087] Compared with the implementation example 1, the input transmission line is the main difference of this implementation example is that the four output transmission lines are all ridge waveguides.

Abstract

The invention discloses a compact double-ridge rectangular waveguide four-way micro-strip power divider. The compact double-ridge rectangular waveguide four-way micro-strip power divider comprises aninput transmission line, four output transmission lines, electromagnetic wave passages, metal ridges and the like, wherein the input transmission line is a double-ridge waveguide; at least one electromagnetic wave passage is arranged between the input transmission line and each output transmission line, and one electromagnetic wave passage is connected with the input transmission line through oneend face, or the corresponding output transmission line, or the other electromagnetic wave passage; more than one electromagnetic wave passage is adjacent along the Z axis and is connected; and the output transmission line is a micro-strip line. The compact double-ridge rectangular waveguide four-way micro-strip power divider has the characteristic that compact bandwidth matching from one transmission line to four transmission lines can be realized at extremely short distance. The compact double-ridge rectangular waveguide four-way micro-strip power divider is mainly used in various communication and radar systems of microwave, millimeter wave and terahertz wave bands.
