The antenna system has two rotationally symmetrical antennas (Ant1,Ant2) which are arranged one above the other and coaxially with respect to its axis of symmetry and two signal sources for independent supply of two antennas with respective antenna. The outer and inner conductors of coaxial line (SL) in each case form one antenna signal carrying conductor for feeding one of the two antennas. Both antennas are at a common ground potential (G). The two antenna signals are inductively separated by two current baluns (TR1,TR2) between coaxial line and respective one of signal sources. |
