Abstract
A shielding structure is provided for shielding a signal path extending between a first layer and a second layer in an electronic device at a transition region with a transition that extends in a first direction and a second direction orthogonal to the first direction. The shielding structure includes a shielding structure portion, which includes a first shielding via in proximity to a first area of the signal path at the transition; a second shielding via in proximity to a second area of the signal path at the transition; and an area metallization electrically coupled to the first shielding via.
