Embodiment 1

[0070] Such as Figure 1a ~ Figure 1e shown.

[0071] A metal-ridge-based double-ridge rectangular waveguide four-way coaxial power splitter 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.

[0072] The input transmission line 2 is a double ridge waveguide.

[0073] The output transmission line 4 is a microstrip line.

[0074] 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.

[0075] 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 .

[0076] Each metal ridge assembly C includes two metal ridge...

Embodiment 2

[0086] Such as Figure 2a~2c shown.

[0087] 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 four output transmission lines are ridge waveguides.

Embodiment 3

[0089] Such as Figure 3a~3d shown.

[0090] Compared with the implementation example 1, the main difference between this implementation example is that no electromagnetic channel 3 is provided.

Abstract

The invention discloses a metal ridge-based double-ridge rectangular waveguide four-way coaxial power divider, which comprises an input transmission line, four output transmission lines, an electromagnetic channel, metal ridges and the like, wherein the input transmission line is a double-ridge waveguide; at least two waveguides and at least four metal ridge assemblies C located in the waveguidesalong a Z direction are arranged between the input transmission line and the output transmission lines; each metal ridge assembly C comprises at least two metal ridges C mutually communicated along the Z direction; each metal ridge C in each metal ridge assembly C is connected with the inner wall of the waveguide where the metal ridge is only in one direction; and the output transmission line is acoaxial line. The metal ridge-based double-ridge rectangular waveguide four-way coaxial power divider is prominently characterized in that compact broadband matching from the one transmission line tothe four transmission lines in a short distance can be realized, and can be mainly used in various communication and radar systems in microwave, millimeter wave and terahertz bands.

Description
