Abstract
A microstrip line device is disclosed of the type which typically includes a strip conductor disposed on the top of a substrate. The device further includes a layer of dielectric material disposed between the strip conductor and the substrate for reducing the dissipation loss in these devices. In order to accomplish this, the dielectric layer has a dielectric constant which is less than the dielectric constant of the substrate.
