A circuit may include a signal path, a first layer including the signal path, and a second layer including the signal path. The circuit may additionally include a path via having a signal-path via location and configured to connect the signal path at the first layer with the signal path at the second layer. The circuit may also include a ground plane associated with the first layer. The ground plane may have a ground-plane location that corresponds to the signal-path via location. The ground plane may also include an asymmetrical cutout portion that extends away from the ground-plane location on a first side of the ground plane that is opposite a second side of the ground plane that corresponds with a side of the first layer where the path via interfaces with the signal path at the first layer.
