Log periodic antenna fed by single zigzag conductor which reduces capacitive loadingon the monopole radiators and reduces cross polarization

Claim 1

A LOG PERIODIC ANTENNA STRUCTURE COMPRISING AT LEAST A FIRST ANTENNA ELEMENT GENERALLY TRIANGULAR IN SHAPE AND HAVING A VERTEX POINTING GENERALLY IN THE DIRECTION OF RADIATION FROM SAID ANTENNA, THE SIDES OF SAID ANTENNA ELEMENT BEING DEFINED BY AN ANGLE A1 MEASURED FROM SAID VERTEX, CENTRAL SUPPORT MEANS HAVING A ZIGZAB SHAPE AND CONSISTING OF A SERIES OF STRAIGHT, CONDUCTIVE ELEMENTS JOINED ENDTO-END WITHOUT BRANCHES BETWEEN SAID ENDS AND LYING IN THE PLANE OF SAID ANTENNA ELEMENT, THE PEAK-TO-PEAK AMPLITUDE OF SAID ZIGZAB SHAPE INCREASING LINEARLY WITH THE DISTANCE FROM SAID VERTEX WITH THE POSITION OF SAID PEAKS BEING DEVINED BY AN ANGLE A2 WHICH IS LESS THAN THE ANGLE A1, AND OF THE ORDER OF 3 TO 7 DEGREES, AND WHOSE BISECTOR COINCIDES WITH THE BISECTOR OF SAID ANGLE A1, THE RADIAL DISTANCE MEASURED FROM SAID VERTEX TO ANY PEAK ON SAID ZIGZAG CENTER SUPPORT MEANS BEARING A CONSTANT RATIO $ TO THE RADIAL DISTANCE TO THE PEAK OF THE ADJACENT PEAK NEXT FARTHEST REMOVED FROM SAID VERTEX AND ON THE SAME SIDE OF THE BISECTOR OF ANGLE A2, THE RADIAL DISTANCE TO A GIVEN PEAK ON ONE SIDE OF SAID BISECTORS BEARING A CONSTANT RATIO $ 1/2 TO THE RADIAL DISTANCE TO THE PEAK NEXT FARTHEST REMOVED FROM SAID VERTEX, BUT ON THE OTHER SIDE OF SAID BISECTORS, AND TEETH COMPRISED OF SUBSTANTIALLY STRAIGHT, CONDUCTIVE RODS EXTENDING TRANSVERSELY OUT FROM EACH OF SAID PEAKS ON EITHER SIDE OF SAID CENTER SUPPORT MEANS, ALL OF THE TEETH ON EACH SIDE OF SAID CENTER SUPPORT MEANS BEING SUBSTANTIALLY PARALLEL WITH EACH OTHER, THE OUTER ENDS OF ALL OF SAID TEETH BEING TERMINATED ON THE LINES FORMING SAID ANGLE A1.
