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