ABSTRACT:
Methods for fabricating a coplanar waveguide structure. The method may include forming first and second ground conductors and a signal conductor in a coplanar arrangement between the first and second ground conductors, forming a first coplanar array of substantially parallel shield conductors above the signal conductor and the first and second ground conductors, and forming a second coplanar array of substantially parallel shield conductors below the signal conductor and the first and second ground conductors. The method further includes forming a first plurality of conductive bridges located laterally between the signal conductor and the first ground conductor, and forming a second plurality of conductive bridges located laterally between the signal conductor and the second ground conductor. Each of the first plurality of conductive bridges connects one of the shield conductors in the first array with one of the shield conductors in the second array. Each of the second plurality of conductive bridges connects one of the shield conductors in the first array with one of the shield conductors in the second array.
