  • Abstract
    In this paper we present a classical circularly polarized helix antenna. The axial ratio of this antenna is improved by a new method using a parasitic element. We describe the effectiveness of this element for various shapes and placements. Finally, we demonstrate the results on a six turn helix antenna.
