Claims

5. A UNDIRECTIONAL BROAD BAND ANTENNA SYSTEM COMPRISING A GENERALLY V-SHAPED ANTENNA HAVING ANGULARLY DISPOSED METAL STRIPS AS RADIATING ELEMENTS, THE ANGLE BETWEEN SAID METAN STRIPS BEING ABOUT 60 DEGREES, THE FLAT PORTIONS OF SAID STRIPS SUBSTANTIALLY FACING ONE ANOTHER THE WIDTH OF SAID STRIPS BEING SUBSTANTIALLY CONSTANT THROUGHOUT THEIR LENGTHS AND BEING SUFFICIENT TO ACHIEVE UNDIRECTIONAL OPERATION, MEANS EXCITING THE V-SHAPED ANTENNA AT ITS APEX SO THAT THE CURRENTS DEVELOPED IN THE MEATAL STRIPS ARE CONCENTRATED ON THE INSIDE SURFACES THEREOF AND PHASE CORRECTION MEANS OPERATIVELY CONNECTED TO AND DISPOSED BETWEEN SAID METAL STRIPS.
