Embodiment 1

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

[0050] A rectangular waveguide four-channel microstrip power divider based on metal ridges includes an input transmission line 2 and four output transmission lines 4, and the axes of the input transmission line 2 and the output transmission line 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 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.

[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. Each metal ridge component C includes two metal ridges C51 connected to each o...

Embodiment 2

[0064] Such as Figure 2a~2d Shown.

[0065] Compared with the first embodiment, the main difference between this embodiment is that the input transmission line is a rectangular waveguide and no electromagnetic channel 3 is provided.

Embodiment 3

[0067] Such as image 3 Shown.

[0068] This implementation example is an actual implementation similar to implementation example 2. Each metal ridge component C includes 4 metal ridges C. The reflection coefficient of the input end of the input transmission line in the working bandwidth of 2.35~2.55GHz is lower than -21.5dB. The total length of each metal ridge assembly C is 40 mm. Therefore, the rectangular waveguide four-channel microstrip power divider based on metal ridges converts the BJ26 waveguide into four microstrip transmission lines within a length of 40 mm, which is convenient to connect with four solid-state power amplifiers to form a four-channel solid-state power and combiner.

Abstract

The invention discloses a metal ridge-based rectangular waveguide and four-microstrip power divider. The power divider comprises an input transmission line, four output transmission lines, an electromagnetic wave channel, metal ridges and the like. The input transmission line is a rectangular waveguide; at least two waveguides and at least four metal ridge components C arranged in a Z direction 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 mutually connected inthe 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 microstrip lines. 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 power divider is mainly used in various communication and radar systems of microwave, millimeter wave and terahertz wave bands.

Description
