Embodiment 1

[0049] Such as Figure 1a ~ Figure 1e shown.

[0050] A compact square waveguide four-way power divider includes an input transmission line 2 and four output transmission lines 4, the axes of the input transmission lines 2 and output transmission lines 4 are along the Z direction.

[0051] The input transmission line 2 is a double ridge waveguide.

[0052] The output transmission line 4 is a microstrip line.

[0053] 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.

[0054] 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 .

[0055] Each metal ridge assembly C includes two metal ridges C51 connected to each other along the Z...

Embodiment 2

[0065] Such as Figure 2a~2d shown.

[0066] The main difference between this implementation example and implementation example 1 is that no metal ridge assembly C or metal ridge assembly D is provided. Both the input transmission line and the output transmission line are rectangular waveguides, connected and matched through an electromagnetic wave channel.

Embodiment 3

[0068] Such as Figure 3a~3d shown.

[0069] Compared with the implementation example 2, this implementation example is only different in that both the input transmission line and the output transmission line are square waveguides. The input transmission line and the output transmission line are matched through two electromagnetic channels of quadrature addition. The matching structure coincides with the original shape after being rotated 90 degrees around the Z axis.

Abstract

The invention discloses a compact square waveguide four-way power divider comprising an input transmission line, four output transmission lines, an electromagnetic wave channel, a metal ridge and thelike. The input transmission line is a square waveguide; at least one electromagnetic wave channel is arranged between the input transmission line and the output transmission lines, and the electromagnetic wave channel communicates with the input transmission line, the output transmission lines or another electromagnetic wave channel through one end surface thereof; more than one electromagnetic wave channel are adjacent to one other along the Z axis and communicates with one other. The output transmission lines are square waveguides. The divider is characterized in that the compact broadbandmatching from one transmission line to four transmission lines can be realized at a very short distance. The present invention is mainly used in various communication and radar systems in microwave, millimeter wave and terahertz bands.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a compact square waveguide four-way power splitter.
