Title:
COPLANAR WAVEGUIDE TRANSMISSION LINE AND DESIGN METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/123719
Kind Code:
A1
Abstract:
Provided in the present invention is a coplanar waveguide transmission line, comprising a first dielectric substrate, a central conductor strip and two grounding conductor strips, wherein the first dielectric substrate has a first surface and a second surface which are arranged opposite each other; the central conductor strip and the grounding conductor strips are all overlapped and fixed to the first surface; and the central conductor strip comprises a first section and a second section, with the width of the first section being greater than that of the second section, such that the first section and the second section form a step structure to achieve impedance matching; the first surface is provided with a rectangular recess that is recessed towards the second surface; and a part of the central conductor strip is overlapped and fixed to the side of the recess that is away from the second surface, such that the recess forms a defected ground structure to achieve impedance matching of radio-frequency signals within a preset frequency range. Further provided in the present invention is a design method for impedance matching of a coplanar waveguide transmission line. Compared with the related art, the technical solution of the present invention achieves good impedance matching and a good transmission index.
