Abstract :
Curves are presented which give the dispersion and impedance characteristics of a flattened helix in the presence of a dielectric material and a metal shield. The impedance curves are very similar to the corresponding curves for a round helix whose circumference is equal to the perimeter of the flattened helix. The flattened helix has dispersion characteristics similar to a round helix whose diameter equals the flattened helix thickness.
