End fire planar dipole array with line transposition between dipoles and impedance increase towards feed

Claim 1

A BROAD-BAND DIRECTIVE ANTENNA ARRAY HAVING A DIRECTION OF GREATER EFFECTIVENESS EXTENDING FROM ITS FRONT END COMPRISING AT LEAST SIX DIPOLE ELEMENTS ARRAYED IN FILE IN HORIZONTALLY SPACED RELATION WITH CORRESPONDING ARMS OF SAID DIPOLE ELEMENTS DISPOSED IN A COMMON PLANE AND AT LEAST SIX ADJACENT ONES OF SAID ELEMENTS BEING OF GRADUATED LENGTH DECREASING TOWARD THE FRONT OF SAID ARRAY, MEANS FOR CONNECTING A SIGNAL TRANSMISSION LINE TO THE FRONT ONE OF SAID ELEMENTS, MEANS FOR CONNECTING EACH OTHER DIPOLE ELEMENT OF SAID ARRAY TO THE DIPOLE ELEMENT FORWARD THEREOF, THE LAST SAID MEANS COMPRISING AN AIRDIELECTRIC TRANSMISSION LINE HARNESS WITH THE CONDUCTORS THEREOF TRANSPOSED TO CONNECT RESPECTIVELY TO OPPOSITE TERMINALS OF EACH PAIR OF ADJACENT DIPOLE ELEMENTS WHICH IT INTERCONNECTS, SAID HARNESS HAVING A LENGTH BETWEEN RESPECTIVE ELEMENTS SUBSTANTIALLY EQUAL TO THE INTER-ELEMENT SPACING, SAID DIPOLE ELEMENTS HAVING DIFFERENT RESPECTIVE IMPEDANCES RELATIVE TO THE IMPEDANCE OF SAID TRANSMISSION LINE HARNESS AT THEIR RESPECTIVE POINTS OF CONNECTION THERETO, SAID ELEMENT RELATIVE IMPEDANCES INCREASING TOWARD THE FRONT OF SAID ARRAY AND CAUSING THE PROPORTION OF ENERGY ABSORBED FROM THE TRANSMISSION LINE HARNESS BY RESPECTIVE DIPOLE ELEMENTS TO BE PROGRESSIVELY GREATER FOR ELEMENTS FARTHER FROM SAID TRANSMISSION LINE CONNECTING MEANS, THE SAID ABSORPTION RELATIONSHIP OBTAINING FOR ANY SET OF THREE ADJACENT ELEMENTS AT AT LEAST ONE OPERATING FREQUENCY WITHIN THE OPERATING RANGE OF SAID ARRAY, AND MEANS FOR DETERMINING THE HARMONIC MODE RADIATION PATTERN AND IMPEDANCE OF CERTAIN OF SAID ELEMENTS COMPRISING CLOSE SPACED SHORT PARASITIC ELEMENTS IN FRONT OF CERTAIN OF SAID DIPOLE ELEMENTS, SAID PARASITIC ELEMENTS CAUSING THE SAID ABSORPTION RELATIONSHIP TO OBTAIN FOR AT LEAST THREE ADJACENT DIPOLE ELEMENTS OF SAID ARRAY THROUGHOUT SAID OPERATING RANGE OF FREQUENCIES, INCLUDING A PORTION OF SAID RANGE WHERE SAID ELEMENTS FUNCTION IN A HARMONIC MODE.
