Embodiment Construction

[0022] Embodiments of the present invention are described in detail below. The embodiments described below are exemplary only for explaining the present invention and should not be construed as limiting the present invention. If no specific technique or condition is indicated in the examples, it shall be carried out according to the technique or condition described in the literature in this field or according to the product specification. The reagents or instruments used were not indicated by the manufacturer, and they were all commercially available conventional products.

[0023] The present invention is based on the following knowledge and findings of the inventors:

[0024] At present, the waveguide is generally a hollow tube. In order to have sufficient mechanical strength to prevent deformation, the thickness of the hollow conductive tube body of the waveguide is generally relatively thick. Therefore, a large amount of metal materials need to be used to meet the needs o...

Abstract

The invention provides a waveguide, a preparation method thereof, and an electronic device. The waveguide includes: a conductive tube body in which a receiving space is defined; and an insulating substrate filling the receiving space. The waveguide with the above structure is simple in structure and easy to machine and form, and does not require huge machining equipment. Since the insulating substrate has a good support effect, the waveguide has good rigidity or strength. The conductive tube body of the waveguide has a thin wall. The waveguide can be easily machined into various complex shapes(such as a small turning radius, a tree or star shape and the like) through the molding of the insulating substrate, which greatly saves conductive materials, and reduces material costs, processing costs, or installation and maintenance cost. The waveguide is easy to install and low in weight and can be used in the aerospace field.

Description

technical field [0001] The invention relates to the technical field of signal conduction, and in particular, to a waveguide, a preparation method thereof, and an electronic device. Background technique [0002] In the rail transit industry, in order to realize the control of the train by the ground control center, real-time communication between the vehicle and the ground is required. Due to its advantages of transmitting electromagnetic wave signals to the destination with minimal loss, the application of waveguide in rail transit can ensure stable and reliable communication between the vehicle and the ground, and has low loss, long transmission distance, and saves the layout of base stations , high reliability. However, the waveguide needs to be laid along the entire track line, the material cost, processing cost and installation cost are high, and the laying is difficult. [0003] Therefore, the current waveguide still needs to be improved. Contents of the invention ...
