Embodiment 1

[0048] Such as Figure 1a ~ Figure 1e shown.

[0049] 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. The input transmission line 2 is a double ridge waveguide.

[0050] The output transmission line 4 is a microstrip line.

[0051] 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.

[0052] 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 . Each metal ridge assembly C includes two metal ridges C51 connected to each other along the Z direction; each m...

Embodiment 2

[0062] Such as Figure 2a-2d shown.

[0063] Compared with the embodiment 1, the main difference of this implementation example is that no metal ridge component C or metal ridge component 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

[0065] Such as Figure 3a-3d shown.

[0066]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. The power divider comprises an input transmission line, four output transmission lines, electromagnetic wave channels, a metal ridge and the like, wherein 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 communicated with the input transmission line, the output transmission lines or another electromagnetic wave channel through one end face; two or more electromagnetic wave channels are adjacent and communicated along the Z axis; the output transmission lines are square waveguides. The power divider is characterized in that compact broadband matching from one transmission line to four transmission lines can be realized in a very short distance, and is mainly applied to various communication and radar systems in microwave, millimeter wave and terahertz bands.
