The antenna system has at least 2 quadrifilary helix antennae (3,4) offset from one another by 90 degrees and provided with double coils (R0,R90; T0,T90) having a 90 degree phase shift, both antennae wound about a cooom longitudinal axis and rotated through an angle of 45 degrees to one another, such that the double coils have the same spacing from the longitudinal axis in a given perpendicular plane. |
