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.
