Embodiment 1

[0073] Such as Figure 1a ~ Figure 1e shown.

[0074] A compact rectangular waveguide four-way coaxial power splitter 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.

[0075] The input transmission line 2 is a double ridge waveguide.

[0076] The output transmission line 4 is a microstrip line.

[0077] 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.

[0078] 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 ...

Embodiment 2

[0088] Such as Figure 2a-2c shown.

[0089] 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

[0091] Such as Figure 3a-3d shown.

[0092] Compared with the implementation example 1, the main difference between this implementation example is that the input transmission line is a rectangular waveguide, and no electromagnetic channel 3 is provided.

Abstract

The invention discloses a compact rectangular waveguide and four-coaxial power divider. The power divider comprises an input transmission line, four output transmission lines, an electromagnetic wavechannel, metal ridges and the like. The input transmission line is a rectangular waveguide; at least one electromagnetic wave channel is arranged between the input transmission line and the output transmission lines; the electromagnetic wave channel is connected with the input transmission line, the output transmission line or another electromagnetic wave channel through one end surface thereof; multiple electromagnetic wave channels are adjacent and connected along a Z axis; and the output transmission lines are coaxial lines. The power divider has the outstanding characteristic that compactwideband matching of one to four transmission lines can be realized in a very short distance. The power divider is mainly used in various communication and radar systems of microwave, millimeter waveand terahertz wave bands.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a compact rectangular waveguide four-way coaxial power divider. Background technique [0002] In various electromagnetic wave systems, signal distribution and combining circuits are widely used. The existing one-to-four power splitter circuits have complex structures, large volumes, or narrow bandwidths. Contents of the invention [0003] The purpose of the present invention is to provide a compact rectangular waveguide four-way coaxial power splitter, which is smaller in volume, simpler in structure, more convenient in processing and wide in operating frequency compared with the prior art. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A compact rectangular waveguide four-way coaxial power divider, including an input transmission line, and four output transmission lines, the axis of the input transmission line a...
