Patent ID: 8028406

Claim:
A method of fabricating a coplanar waveguide structure, the method comprising: forming first and second ground conductors and a signal conductor in a coplanar arrangement with the signal conductor arranged laterally 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; forming a second coplanar array of substantially parallel shield conductors below the signal conductor and the first and second ground conductors; forming a first plurality of conductive bridges located laterally between the signal conductor and the first ground conductor, each of the first plurality of conductive bridges connecting one of the shield conductors in the first array with one of the shield conductors in the second array; and forming a second plurality of conductive bridges located laterally between the signal conductor and the second ground conductor, each of the second plurality of conductive bridges connecting one of the shield conductors in the first array with one of the shield conductors in the second array.
