Abstract

The invention relates to the field of microstrip line, provides a microstrip line which comprises a metal strip, a dielectric substrate and an earth plate. The dielectric substrate is formed by an FR (fire resistance)-4 filled with hollow glass beads; the microstrip line also comprises a metamaterial thin film, the metamaterial thin film and the metal strip are arranged on one side of the dielectric substrate and all appressed to the dielectric substrate. Wherein 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 utilizing the dielectric substrate which is formed by mixing the hollow glass beads and the FR-4 can effectively inhabit the space wave leakage of the microstrip line and solve the problem of electromagnetic wave crosstalk between the adjacent microstrip lines.

Description

technical field

[0001] The invention relates to the field of microwave communication, more specifically, to a microstrip line. 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). Such as 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.
