Embodiment 1

[0061] Such as Figure 1a ~ Figure 1e shown.

[0062] A metal-ridge-based double-ridge rectangular waveguide four-way ridge waveguide 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.

[0063] The input transmission line 2 is a double ridge waveguide.

[0064] The output transmission line 4 is a microstrip line.

[0065]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.

[0066] 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 component C includes two metal ridges...

Embodiment 2

[0076] Such as Figure 2a-2e shown.

[0077] The input transmission line is the main difference between this implementation example and implementation example 1 is that the four output transmission lines are all ridge waveguides.

Embodiment 3

[0079] Such as Figure 3a-3d shown.

[0080] Compared with Example 2, the input transmission line is a rectangular waveguide, the waveguide 5 and the metal ridge C are omitted, and a filter structure consisting of 4 microwave transmission lines and several metal ridges E is added to form a compact quadruplexer.

Abstract

The invention discloses a metal ridge-based dual-ridge rectangular waveguide and four-ridge waveguide power divider. The power divider comprises an input transmission line, four output transmission lines, electromagnetic wave channels, metal ridges and the like. The input transmission line is a dual-ridge waveguide; at least two waveguides and at least four metal ridge components C arranged in a Zdirection and located in the waveguides are arranged between the input transmission line and the output transmission lines; each metal ridge component C comprises at least two metal ridges C mutuallyconnected in the Z direction; each metal ridge C in each metal ridge component C is connected with the inner wall of the corresponding waveguide in the same direction only; and the output transmission lines are ridge waveguides. The power divider has the outstanding characteristic that compact wideband matching of one to four transmission lines can be realized in a very short distance. The powerdivider is mainly used in various communication and radar systems of microwave, millimeter wave and terahertz wave bands.

Description
