Embodiment 1

[0054] like Figure 1a ~ Figure 1e shown.

[0055] A compact rectangular waveguide four-way microstrip 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.

[0056] The input transmission line 2 is a double ridge waveguide.

[0057] The output transmission line 4 is a microstrip line.

[0058] 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.

[0059] 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

[0069] like Figure 2a~2c shown.

[0070] 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

[0072] like Figure 3a-3d shown.

[0073] 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-way micro-strip power divider which comprises an input transmission line, four output transmission lines, electromagnetic wave channels, ametal ridge and the like. The input transmission line is provided with a rectangular waveguide, at least one electromagnetic wave channel is formed among the input transmission line and the output transmission lines, one electromagnetic wave channel is communicated with the input transmission line or the output transmission lines or the other electromagnetic wave channel through one end surface ofthe electromagnetic wave channel, more than one electromagnetic wave channel is adjacent and communicated along a Z axis, and the output transmission lines are provided with micro-strip lines. The power divider has remarkable advantages that compact broadband matching of one transmission line to four transmission lines can be achieved in a short distance. The power divider is mainly used for various communication and radar systems of microwaves, millimeter waves and terahertz wave bands.

Description

technical field [0001] The invention relates to a power divider. Specifically, it relates to a compact rectangular waveguide four-way microstrip power splitter. 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 microstrip power divider, 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 microstrip power divider, including an input transmission line, and four output transmission lines, the axis of the input transmissi...
