Embodiment 1

[0055] Such as Figure 1a ~ Figure 1e shown.

[0056] A compact rectangular waveguide four-way microstrip 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.

[0057] The input transmission line 2 is a double ridge waveguide.

[0058] The output transmission line 4 is a microstrip line.

[0059] 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.

[0060] 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 .

[0061] Each metal ridge component C includes two metal ridges C51 connected to ...

Embodiment 2

[0071] Such as Figure 2a~2c shown.

[0072] 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

[0074] Such as Figure 3a~3d shown.

[0075] Compared with the implementation example 1, the main difference between this implementation example is that the input transmission line is a rectangular waveguide. No electromagnetic channel 3 is set.

Abstract

The invention discloses a compact rectangular waveguide four-path micro-strip power divider which comprises an input transmission line, four output transmission lines, electromagnetic wave channels, metal ridges and the like. The input transmission line is a rectangular waveguide; at least one electromagnetic wave channel is formed between the input transmission line and the output transmission lines; each electromagnetic wave channel is communicated with the input transmission line, or the output transmission lines, or another electromagnetic wave channel by one end face of the electromagnetic wave channel; more than one electromagnetic wave channel are adjacent and are communicated along a Z axis; and the output transmission lines are micro-strip lines. The compact rectangular waveguidefour-path micro-strip power divider has the outstanding characteristic that in a very short distance, compact broadband matching from one transmission line to four transmission lines can be implemented. The compact rectangular waveguide four-path micro-strip power divider is mainly used in various communication and radar systems on microwave, millimeter wave and terahertz wave bands.
