Abstract
The bifilar scanning helical antenna is analyzed by considering the structu re to carry a single traveling wave. It is shown that the relative phase ve locity (v/c) must equal unity to yield the scanning features shown by numer ical experiment. This is at complete odds with monofilament helices (Kraus) , which display a slow wave structure.
