Claim:
An electrical circuit arrangement for a filter using concentrated capacitors comprising: a substrate; and at least two conductive surfaces each having two dimensions, wherein the substrate comprises at least one layer, at least one layer of the substrate is disposed between the conductive surfaces, the conductive surfaces form a capacitor, the conductive surfaces overlap at least in part and form an overlapping area, the resulting overlapping area is largely constant at displacement in the two dimensions of the conductive surfaces relative to one another up to a threshold value, at least one of the conductive surfaces is smaller in at least one dimension than at least another of the conductive surfaces, and the at least one smaller conductive surface in this dimension is overlapped in this dimension on two sides by the at least one conductive surface larger in this dimension, wherein displacement of the conductive surfaces relative to one another does not significantly alter capacitance, wherein in each case, at least two conductive surfaces are disposed on at least two sides of the at least one layer of the substrate, wherein to each conductive surface on one side of the at least one layer of the substrate, at least one further conductive surface is allocated on the other side of the at least one layer of the substrate, wherein the mutually allocated conductive surfaces overlap at least in part and form an overlapping area, wherein the mutually allocated conductive surfaces form capacitors, and wherein the at least two capacitors formed in this manner are connected in parallel, wherein the first conductive surface of the first capacitor and the first conductive surface of the second capacitor is disposed on the first side of the at least one layer of the substrate, wherein the second conductive surface of the first capacitor and the second conductive surface of the second capacitor is disposed on the second side of the at least one layer of the substrate, wherein the first conductive surface of the first capacitor is connected to the second conductive surface of the second capacitor via a first connection from one side of the electrical circuit arrangement, and wherein the first conductive surface of the second capacitor is connected to the second conductive surface of the first capacitor via a second connection from another side of the electrical circuit arrangement.
