Definition

Dual stripline places two signal layers sandwiched between outer reference ground planes, with the two routing layers typically oriented orthogonally (90 degrees to each other) to minimize interlayer crosstalk. This high-density configuration effectively creates two offset striplines sharing the same outer ground planes. The orthogonal routing prevents long parallel runs that would couple signals between the two signal layers. Dual stripline is common in designs where routing density is critical and layer count must be minimized.
