Patent ID: 8878729

Claim:
An electric conductive trace comprising an arch-shaped variation of a shape of at least a portion of a fractal of at least a second iteration, the portion of the fractal being larger than double of a first iteration of the fractal, the shape varied to be arch-shaped comprising, for changes of direction, a curve radius larger than a predefined minimum curve radius, wherein the predefined minimum curve radius of the arch-shaped variation is equal to R m ⁢ ⁢ i ⁢ ⁢ n = W 2 ⁢ ( 2 - 1 ) + D m ⁢ ⁢ i ⁢ ⁢ n 2 , wherein W is the width of the electric conductive trace and D min is a minimum distance between two rings of a raster that are arranged in the corner points of a square and are diagonally arranged toward one another.
