Abstract
An apparatus for routing electrical signals is a layered structure having a signal trace connected to a via and to a conductive stub trace on a first side. A reference layer is on a second side of the layered structure. Removing a portion of the conductive reference layer in an area of the stub strace increases the impedance of the stub trace without changing the impedance of the signal trace thereby improving an impedance match to another electrical element to which the apparatus is connected.
