Phase scan antenna system

Claim 1

A MULTI-PROBE PHASE SCAN ANTENNA SYSTEM FOR OPERATION OVER A LARGE DYNAMIC RANGE COMPRISING THREE DIELECTRIC ROD ANTENNA ELEMENTS SPACED EQUIDISTANTLY FROM EACH OTHER TO FORM AN ARRAY THEREOF, THREE COAXIAL MAGIC-T ISOLATING DEVICES, AND A COAXIAL PHASE SHIFTER, THE SIGNAL OUTPUT OF EACH OF SAID ANTENNA ELEMENTS BEING CONNECTED THROUGH RESPECTIVE TRANSMISSION LINES TO A RESPECTIVE ONE OF SAID ISOLATING DEVICES, EACH OF SAID ISOLATING DEVICES BEING OPERABLE TO DIVIDE THE SIGNAL OUTPUT FROM ITS RESPECTIVE ANTENNA ELEMENT INTO-TWO PARTS, ONE PART OF SAID DIVIDED SIGNAL OUTPUT FROM EACH OF SAID ISOLATING DEVICES BEING FED THROUGH TRANSISSION LINES TO A FIRST JUNCTION, THE OUTPUT OF SAID FIRST JUNCTION BEING THE NON-SCANNING SIGNAL FROM SAID ANTENNA SYSTEM, THE PART OF SAID DIVIDED SIGNAL OUTPUT FROM EACH OF SAID ISOLTAING DEVICES BEING FED THROUGH TRANSMISSION LINES TO RESPECTIVE INPUTS OF SAID COAXIAL PHASE SHIFTER, RESPECTIVE OUTPUTS OF SAID COAXIAL PHASE SHIFTER BEING FED TO SECOND JUNCTION, THE OUTPUT OF SAID SECOND JUNCTION BEING THE SCANNING SIGNAL FROM SAID ANTENNA SYSTEM, SAID ISOLATING DEVICES ALSO OPERATING TO PREVENT ALL OF SAID ANTENNA ELEMENTS FROM BEING INTERCONNECTED AND PREVENTING ANY FEEDBACK FROM SAID FIRST JUNCTION TO SAID SECOND JUNCTION, THE DIRECTION IN WHICH THE ANTENNA SYSTEM IS LOOKING BEING CHANGED IF DESIRED WITHOUT MECHANICALLY POINTING THE ANTENNA SYSTEM BY INTRODUCING ADDITIONAL PHASE SHIFT INTO ABY OF THE LINES FROM SAID ANTENNA ELEMENTS, WHEREBY SAID ANTENNA SYSTEM IS DEPOLARIZED AND BOTH SCAN AND NON-SCAN SIGNALS ARE OBTAINED FROM THE ANTENNA ARRAY OF ELEMENTS.
