Embodiment Construction

[0028] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0029] Such as figure 1 , figure 2 , image 3 As shown, the structure of the present invention is mainly composed of a rectangular waveguide 2, a metal sheet 3, a support rod 10 and a moving mechanism of the metal sheet 3; wherein the two sides of the rectangular waveguide are provided with sealing rings 1 for realizing the vacuum seal at the waveguide flange ,; Rectangular waveguide 2 is used to transmit high-power microwaves. In order to realize the waveguide size required by the phase shifter, the dimensions of the wide and narrow sides of the rectangular waveguide will transition from the standard waveguide to the size required by the phase shifter; in the rectangular waveguide 2 cavities There is a metal sheet 3 in the body, which is the core component of the phase shifter, and is use...

Abstract

The invention discloses a metal sheet high-power waveguide phase shifter. The metal sheet high-power waveguide phase shifter comprises a rectangular waveguide, a metal sheet, a supporting rod, a supporting seat, a threaded rod and a cover plate, wherein two supporting legs of the supporting rod penetrate through one side of the rectangular waveguide to be connected with the metal arranged in a cavity of the rectangular waveguide, the supporting rod is sleeved with the supporting seat, the cover plate is fixedly arranged on the supporting seat through screws, the threaded rod penetrates through the cover plate and the supporting seat in sequence to be connected with the supporting rod through threads, and a bearing structure is arranged between the threaded rod and the cover plate. Compared with a traditional waveguide phase shifter, approximately-linear phase change of the waveguide within the range from 0 degree to 360 degrees can be achieved by the arrangement of the metal sheet, and the problem that the metal sheet is broken down when the metal sheet high-power waveguide phase shifter works in a high-power environment can be avoided.

Description

technical field [0001] The invention relates to the technical field of high-power microwaves, in particular to a metal sheet high-power waveguide phase shifter. Background technique [0002] At present, an important development requirement of high-power microwave is to realize beam scanning of antenna array, and phase shifter is a key component to realize array beam scanning. At present, there are two main types of conventional phase shifters: semiconductor diode phase shifters and ferrite phase shifters. The peak power capacity of conventional phase shifters does not exceed 100kW, while the peak power of high-power microwaves is not less than 100MW. Therefore, the power capacity of conventional phase shifters is small and is not suitable for high-power microwaves. [0003] For this reason, research institutes at home and abroad have launched research on high-power microwave phase shifters, but these research results are still far from practical engineering applications.
