Microstrip lines based on metamaterials

Abstract

The invention relates to the field of microstrip lines and provides 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; and the earth plate is arranged on the other side of the dielectric substrate. The microstrip line has the beneficial effects that space wave leak can be effectively restricted and the problem of electromagnetic wave crosstalk between microstrip lines is solved.

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 (MicrostripLine) is currently a planar transmission line most used in Hybrid Microwave Integrated Circuits (HMIC) and Monolithic Microwave Integrated Circuits (MMIC). like figure 1 As shown, from a structural point of view, the microstrip line is placed on a ground plate 3 by a very thin metal strip 1 at an interval much smaller than the wavelength, and the metal strip 1 and the ground plate 2 are separated by a dielectric substrate 3 . [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.
