Substrate Integrated Suspended Line

Transmission lines are the most basic components of microwave and millimeter-wave circuits and systems. The size and performance of circuits and systems will be affected by the size, loss, transmission and other characteristics of the structure. Non-planar transmission lines include metal waveguides, coaxial lines, and suspended strip lines, and planar transmission lines include microstrip, slot lines, and strip lines. These are commonly used microwave transmission lines. Among them, the suspended stripline has proved to be a very good transmission line system.
