Claim of US Patent No. 9,462,676

1. A multi-layer circuit member comprising:
first and second spaced apart, generally parallel conductive reference planes;
an electrically conductive via extending between the first and second reference planes to electrically interconnect the first
and second reference planes;

a first signal conductor adjacent a first region of the first reference plane;
at least one component adjacent to and operative to transfer energy to the second reference plane; and
an elongated area of increased impedance in the first reference plane located between the first region of the first reference
plane and the via, wherein the elongated area of increased impedance is an elongated slot in the first reference plane, the
elongated slot having two opposing sides and two ends, wherein the two sides of the elongated slot are not in direct electrical
communication except at the ends of the elongated slot or through the via.
