Embodiment Construction

[0024] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0025] The present invention provides a waveguide nine-way equally divided output power distribution structure, such as figure 1 As shown, it includes: eight T-shaped cavities 1-8, one waveguide-type nine-way equal-section output power distribution structure inlet 9 and nine waveguide-type nine-way equal-section output power distribution structure outlets;

[0026] Each T-shaped cavity includes a vertical port, two horizontal ports and a rectangular protrusion. The vertical port is the entrance of the T-shaped cavity, and the two horizontal ports are the outlets of the T-shaped cavity. In each T-shaped The intersection of the vertical port and the horizontal port of the cavity has a rectangular protrusion facing the vertical port; the rectangular protrusion of the T-shaped cavity is perpendicular to the horizontal port. The length and width of the rectangular protrus...

Abstract

The invention discloses a waveguide mode nine-channel equal output power distribution structure. The structure comprises 8 T-type cavities, a waveguide mode nine-channel equal output power distribution structure entrance and 9 waveguide mode nine-channel equal output power distribution structure exits, wherein each of T-type cavities comprises a vertical port, two transverse ports and a rectangular projection, the vertical ports are entrances of the T-type cavities, transverse ports are exists of T-type cavities, rectangular projections are arranged at intersection positions of vertical ports and transverse ports of T-type cavities and face towards vertical ports, the first cavity, the third cavity, the fifth cavity and the sixth cavity are in a distribution structure of 1:2, the second cavity, the fourth cavity, the seventh cavity and the eighth cavity are in a distribution structure of 1:1, and 9 waveguide mode nine-channel equal output power distribution structure exits are output exits at 90 degrees. The structure is compact, easy to process and little in inserting loss. By the aid of the proportional zooming, the structure can be applied to nine-channel power distribution and synthesis of millimeter waves and sub- millimeter wave bands.

Description

technical field [0001] The invention relates to a waveguide type nine-way equally divided output power distribution structure, which is a microwave waveguide device and belongs to the technical field of microwave waveguide device design. Background technique [0002] Rectangular metal waveguide power divider is an important passive device widely used in microwave and millimeter wave communication systems. It has the characteristics of high power capacity, small loss, and low insertion loss. There are many forms of waveguide power dividers, the common ones are T branch, Y branch, waveguide directional coupler, waveguide branch line coupler and so on. [0003] The waveguide T-shaped structure is a commonly used power distribution structure, which has the characteristics of simple structure, small size, and flexible application, but its own structure has discontinuity, which will cause strong reflection and large attenuation. Reflection and attenuation can be reduced by using ...
