Abstract
A microstrip line structure includes a conductive ground plane having a strip opening encircled by the ground plane. The strip opening extends from a top surface to a bottom surface of the ground plane. The microstrip line structure further includes a dielectric strip filling the strip opening; a dielectric layer over and contacting the ground plane; and a signal line over the dielectric layer, wherein the signal line has a portion directly above a portion of the dielectric strip, and wherein the signal line and the dielectric strip are non-parallel.
