It is shown that the combination of low pitch and a small number of turns realizes a low-profile helix as a radiating element of circular polarization. A two-turn helix of 4° pitch angle shows a bandwidth of 12% for a 3 dB axial-ratio criterion. The numerical results presented lead to new aspects of a low-pitch helix as an effective radiating element
