Abstract
The invention relates to a metamaterial-based microstrip line. The microstrip line comprises a metal strip, a dielectric substrate, an earth plate and a metamaterial thin film, wherein the metamaterial thin film and the metal strip are arranged on the same side of the dielectric substrate and cling to the dielectric substrate; the metamaterial thin film covers the metal strip; the earth plate is arranged on the other side of the dielectric substrate; and the dielectric substrate is a metamaterial substrate which comprises a plurality of first metamaterial sheet layers with the same refractive index distribution. The microstrip line has the beneficial effects that leak of the space wave form of the microstrip line is effectively restricted via the metamaterial thin film and the metamaterial substrate and then electromagnetic wave crosstalk between the microstrip lines is greatly reduced.
Description
technical field [0001] The invention relates to the field of microstrip lines, more specifically, to a microstrip line based on metamaterials. Background technique [0002] Microstrip Line (Microstrip Line) is currently the most widely used planar transmission line in Hybrid Microwave Integrated Circuits (HMIC) and Monolithic Microwave Integrated Circuits (MMIC). From a structural point of view, the microstrip line is placed on a ground plate by a very thin metal strip at an interval much smaller than the wavelength, and the metal strip and the ground plate are separated by a dielectric substrate. [0003] The outstanding advantages of microstrip lines are compact structure and light weight. Complex microwave circuits can be made in a small volume by stereolithography, photolithography, corrosion and other processes, and it is easy to integrate with other microwave devices to realize microwave components and systems. integration. [0004] With the miniaturization of microw...
