Abstract:
Multi-layer in integrated transmission line circuits are provided having improved signal loss characteristics. A multi-layer integrated transmission line circuit, such as a stripline circuit or a microstrip circuit, comprises at least one reference layer; at least one conducting layer having one or more conducting strips, wherein the at least one conducting layer is separated from the at least one reference layer by a substrate; and at least one additional layer positioned between the at least one conducting layer and the at least one reference layer. The multi-layer integrated transmission line circuit may also comprise a dielectric insulating material, such as an organic material or a ceramic material. The additional layers increase a dielectric thickness of the multi-layer integrated transmission line circuit to reduce dielectric losses.
