Abstract

The invention discloses an ultra-wideband terahertz waveguide filter. The filter includes: a standard rectangular waveguide, an arc-shaped gradient waveguide, a height-reducing waveguide, a waveguide short-circuit branch, and a resonant waveguide cavity, wherein the standard rectangular waveguide, the arc-shaped Gradient waveguide, height-reducing waveguide, resonant waveguide cavity, height-reducing waveguide, arc-shaped gradient waveguide, and standard rectangular waveguide are sequentially connected from left to right to form the filter, and N waveguide short-circuit branches are arranged on both sides of the height-reducing waveguide section, the N is a positive integer greater than or equal to 2, the end of the short-circuit branch of the waveguide is provided with a chamfer, and the filter is symmetrical with respect to the horizontal centerline and the vertical centerline of the filter, so that the terahertz Ultra-broadband filtering function in the frequency band, simple processing, stable structure, and technical effects of small installation errors.

Description

technical field [0001] The invention relates to the research field of waveguide filters, in particular to an ultra-wideband terahertz waveguide filter. Background technique [0002] With the development of ultra-wideband technology, ultra-wideband filters are becoming more and more important, and the requirements for ultra-wideband filters are getting higher and higher. The emergence of new technologies and new processes makes the design theory of ultra-wideband filters constantly Rich and perfect, but the current development of ultra-wideband filter structures is mainly concentrated in microstrip lines, suspended microstrip lines and coplanar waveguides. These structures are mainly used in low frequency bands or microwave and millimeter wave frequency bands. When the communication frequency band rises to After the terahertz frequency band, these structures will face a series of problems such as fewer design structure options, difficult processing, low processing accuracy, a...
