Abstract

The invention discloses a medium-integrated suspension line structure based on metamaterials, including a medium-integrated suspension line platform, and the medium-integrated suspension line platform includes six-layer circuit boards stacked from top to bottom, and each layer of circuit boards It includes the upper and lower metal layers and the dielectric layer arranged between the upper and lower metal layers, wherein the second and fifth layer circuit boards are provided with air cavities, and the fourth layer circuit board is provided with a metamaterial structure. The material structure includes two ends and a connecting portion connected between the two ends, and the cross-sectional area of ​​the connecting portion is smaller than that of the end portion. It introduces the metamaterial structure into the dielectric integrated suspension line structure, effectively reduces the circuit size, and realizes circuit miniaturization.

Description

technical field [0001] The invention relates to the technical field of radio frequency circuits and microwave and millimeter wave circuits, in particular to a medium-integrated suspension wire structure based on metamaterials. Background technique [0002] With the rapid development of modern communication and radar technology, higher and higher requirements are put forward for the high performance, miniaturization, light weight, planarization, modularization and reliability of microwave and millimeter wave systems. As the most basic component of microwave and millimeter wave circuits and systems, transmission lines, their size, loss, transmission and other characteristics directly or indirectly determine the size and performance of microwave and millimeter wave circuits and systems. [0003] The waveguide suspension line is a transmission line with excellent performance. Compared with other planar transmission lines, the metal loss is greatly reduced due to its larger cross...
