摘要：
The radiation characteristics of a quadrifilar conical helix antenna are analysed. Special attention is paid to the generation of a circularly polarised wave over a hemispherical region above the antenna. The present antenna has wideband characteristics with respect to the radiation pattern and the input impedance by virtue of the radiation mechanism characterised by a travelling-wave current. The effects of the cone angle and the pitch angle on the radiation field are also investigated.
