Preparation process of a 90-degree ultra-thin rotating twisted waveguide

Abstract

The invention discloses a preparation process of a 90-degree ultra-thin rotating twisted waveguide, which includes the following steps: S101, pre-preparing a 90-degree rotating shape part 1 and a standard part matching the 90-degree rotating waveguide cavity; S103, preparing for assembly and soldered external part 2, wherein the external part 2 includes an assembly groove and a fixing slot for matching with the 90-degree rotating external part 1; S105, interference fitting the obtained 90-degree rotating external part 1 into the obtained The shape of the second middle. By pre-preparing the 90-degree rotating outer part 1 and the outer part, the 90-degree rotating outer part 1 is dissolved with acid and alkali solution after assembly, and the 90-degree rotating waveguide cavity is retained, and the 90-degree rotation is realized by electroplating, welding and cutting. The preparation of the ultra-thin twisted twisted waveguide not only has a simple process for processing finished products, but also has a high yield rate, and waste materials can be reused, which is beneficial to environmental protection. In addition, the finished product of the 90-degree ultrathin twisted twisted waveguide through the preparation process has excellent electrical properties.

Description

technical field [0001] The invention relates to the technical field of twisted waveguides, in particular to a preparation process of a 90-degree ultra-thin twisted twisted waveguide. Background technique [0002] Twisted waveguide is also called waveguide twist joint. The directions of the broadside and narrowside at both ends are interchanged by 90° for the waveguide. Its characteristic is that the electromagnetic wave passes through it, the polarization direction changes by 90°, and the propagation direction remains unchanged. When connecting waveguides, if the broad side and narrow side of the two waveguides before and after are opposite, it is necessary to insert this twisted waveguide as a transition. The length of the twisted waveguide should be an integer multiple of λg / 2, and the shortest should not be less than 2λg (λg is the wavelength of the waveguide). [0003] The basic principle of electroforming is to obtain the required metal layer by electrolysis, so that...
