Abstract
The invention discloses a half-mold-substrate-integrated-waveguide-based metamaterial transmission line filter comprising an upper dielectric layer, a dielectric substrate, and a lower dielectric layer that are arranged from top to bottom. The upper and lower surfaces of the dielectric substrate are respectively connected with an upper metal sheet and a lower metal sheet; the upper metal sheet is connected with the upper dielectric layer; and the lower metal sheet is connected with the lower dielectric layer. A plurality of dielectric substrate metal through holes arranged successively at intervals are distributed at one side of the dielectric substrate; the upper metal sheet and the lower metal sheet are connected through the dielectric substrate metal through holes. The two ends of the dielectric substrate are respectively provided with an input terminal and an output terminal; a microwave signal enters the upper metal sheet through the input terminal and then is outputted through the output terminal. The filter has advantages of small size, high Q value, convenient integration, and low cost; miniaturization of the integrated waveguide filter is realized; and the application range of the integrated waveguide is expanded.
Description
technical field [0001] The invention belongs to the field of microwave and millimeter wave technology, and in particular relates to a half-mode substrate integrated waveguide metamaterial transmission line filter. Background technique [0002] Metamaterial transmission lines have received extensive attention and interest due to their unique electromagnetic properties. Composite left-handed transmission line (CRLH) as a new type of transmission line structure, it can show the characteristics of left-handed material structure at the low frequency stage lower than the switching frequency, and it can show the right-handed material structure characteristics at the high frequency stage higher than the switching frequency , based on these unique properties, the composite left-handed transmission line structure can realize some unique microwave components that are not easy to realize with the traditional waveguide structure. The left-handed characteristics of the composite left-han...
