Abstract:
The disclosure discloses a low-loss transmission line structure, which belongs to the field of radio frequency transmission lines and includes at least two metal layers stacked in a vertical manner. A dielectric layer is filled between the metal layers. The metal layers include a signal transmission strip in a middle portion. Ground strips are provided on both sides of the signal transmission strip. Through holes are evenly distributed on the dielectric layer, and the signal transmission strips on each of the metal layers are connected through the through holes to form a signal transmission line. The ground strips on each metal layer are connected through the through holes.
