Patent ID: 8378759

Claim:
An apparatus for reducing crosstalk comprising: a substrate having a bottom surface and a top surface defining a horizontal plane; a ground plane coupled to the bottom surface of the substrate; first and second microstrip lines formed on the top surface of the substrate, the first and second microstrip lines formed on the top surface of the substrate and spaced apart from one another; a first plurality of vias traveling through the substrate from the top surface of the substrate to the ground plane and positioned between the first and second microstrip lines for reducing crosstalk between the first and second microstrip lines, the first plurality of vias including a first row of vias and a second row of vias positioned parallel to the first row of vias to form a double via fence; and a second plurality of vias traveling through the substrate from the top surface of the substrate to the ground plane and positioned between the first and second microstrip lines for reducing crosstalk between the first and second microstrip lines.
