Abstract

The invention relates to a terahertz soft waveguide tube based on a PTFE material and a forming method of the terahertz soft waveguide tubethereof. The forming method comprises the steps that throughelectromagnetic characteristic simulation analysis, a terahertz soft waveguide tube structure with a cavity made of PTFE serving as a medium is obtained through electromagnetic characteristic simulation analysis; according to the terahertz soft waveguide tube structure, frequency second laser cutting or CNC is adopted for machining according to the terahertz soft waveguide tube structure, and initial forming of the structure is achieved; coating a metal-plated layer is coated on the preliminarily formed structure by adopting a composite laser direct forming technology to obtain a metal-platedlayer structure; enveloping the outer layer of the metal-plated layer structure is enveloped to realize physical protection and obtain an enveloping structure; and connecting the metal layers at the two ends of the enveloping structure are connected with the waveguide flange plate, coating the reserved metal areas at the two ends of the structure are coated with a silver conductive medium adhesive, and realizing adhesion is realized through curing, thereby obtaining the terahertz soft waveguide tube. The forming method is suitable for a soft waveguide tube forming method for transmitting high-frequency electromagnetic signals in a narrow cavity, and is not limited to the rectangular section size and the length size.

Description

technical field [0001] The invention belongs to the field of electronics, and in particular relates to a PTFE-based terahertz flexible waveguide and a forming method thereof. Background technique [0002] Soft waveguides are mainly used in satellite communication antennas, and have the following two functions: one is to eliminate the assembly error between hard waveguides; the other is to use the deformability of soft waveguides to realize the pointing fine-tuning. The inner wall of the traditional low-frequency flexible waveguide has a corrugated structure, which has good flexibility and can withstand complex bending, stretching and compression, so it is widely used in the connection between microwave equipment and feeders. The reason why the traditional flexible waveguide can provide a certain amount of deformation is because the wall thickness of the flexible waveguide itself is small, about 0.1-0.3mm, and the structure is similar to many disc springs connected in series...
