Abstract. Multi-conductor quadrifilar helix antennas are considered. Such antenna contains four helix radiators. Each of them consists of several metal conductors. The following variants of multi-conductor quadrifilar helix antennas are investigated: quarter – wavelength with two and three conductors and half – wavelength with two and three conductors. Phenomenological theory of such antennas is proposed. Results of numerical and experimental investigation of such antennas are presented.

 

Keywords: quadrifilar antenna, helix antenna, multi-conductor helix antenna.
