Abstract

The invention discloses a manufacturing method of a terahertz corrugated feed source horn, which converts a three-dimensional annular inner cavity tooth-slot microstructure difficult to be processed into a two-dimensional planar lamination structure easy to be electroformed, wherein the lamination width is the inner cavity tooth width or slot width. The manufacturing method specifically comprisesthe steps of fabricating laminations required by the feed source horn in advance; setting an adhesive layer on at least one side of each lamination; then stacking the laminations, wherein the lamination with the smallest inner diameter is placed at the bottom layer of an assembly base when the laminations are stacked, and the stacked laminations are of a horn-shaped structure; and performing vacuum thermocompression bonding on the laminations stacked into the shape of a horn to form the terahertz corrugated feed source horn. The manufacturing method solves a problem that it is difficult to process an inner corrugated microstructure of the high-frequency corrugated feed source horn according to the traditional technology.

Description

technical field [0001] The invention relates to the technical field of precision and ultra-precision device processing, in particular to a method for manufacturing a terahertz corrugated feed horn based on LIGA-precision assembly technology. Background technique [0002] Terahertz (THz) refers to electromagnetic waves with a frequency between 0.1THz and 10THz. It belongs to the far-infrared band and has technical advantages such as large bandwidth, high resolution and strong penetration. The satellite is equipped with a high-performance THz detector to achieve precise detection of elements such as the atmosphere, ocean and space environment. In the antenna feed system of the detector, the feed horn is a high-gain concentrated antenna radiator located in the antenna feed system. Between the surface antenna and the receiver, it is a key component of the detection system, and its structural form, structural parameters and processing accuracy directly affect the performance of t...
