Abstract: A low-loss spiral coil includes a conducting wire wound N turns of which a width of each of wires corresponding to each of sections of the conducting wire is determined by setting an entire width of the conducting wire to be a width of M sections of the conducting wire, and then determining the width of each of the wires such that a resistance of the spiral coil formed based on the width of the M sections is minimized.
