Abstract
Abstract A transmission line comprising first and second planar dielectric layers. Each layer has a first surface and a second surface. The first surface of each layer has a plurality of electrical conductors thereon defining a center conductor and at least two other conductors, one on either side of and spaced from the center conductor. The second surface of each layer has an electrically conductive ground plane thereon. The first surface of one layer is opposed to the first surface of the other layer, with the conductors on the first surface of the one layer being in registry with and in physical and electrical contact with the conductors on the first surface of the other layer. A plurality of conductors are provided for making electrical contact with the ground planes and each of the at least two conductors for causing the ground planes and each of the at least two conductors to be at substantially the same electrical potential.
