1. A circuit board, comprising:
a reticulated conductor including:
a first conductor group that includes a first plurality of conductors having a first periodic width in a first direction, wherein each conductor of the first plurality of conductors has a first conductor width;
a second conductor group that includes a second plurality of conductors having a second periodic width in a second direction orthogonal to the first direction, wherein each conductor of the second plurality of conductors has a second conductor width;
a moving conductor group at a position to which at least a part of the second conductor group is moved by a factor of 1 of the first periodic width in the first direction and is moved by a factor of 1 of a third periodic width in the second direction, wherein the third periodic width is different from the second periodic width; and
a gap region; and
a non-reticulated conductor in the gap region,
wherein the non-reticulated conductor includes:
a first face separated from the first conductor group by a first gap width in the first direction;
a second face separated from the first conductor group by a second gap width in the first direction;
a third face separated from the second conductor group by a third gap width in the second direction; and
a fourth face separated from the second conductor group by a fourth gap width in the second direction.
