Warning -- the following is reasoned guesswork before my second cup of coffee...

Since it is not really the width of the rod elements that is important, but
rather the surface area (derived from the circumference 2*pi*r), I would think
that the width of the foils on the pc board should correspond to the
circumference of the rod elements, and should be calculated as Diameter*pi
