Array antennas utilizing grouped radiating elements
Abstract
Abstract AN ARRAY ANTENNA WHEREIN THE RADIATING ELEMENTS ARE QUANTIZED INTO GROUPS OF ELEMENTS. EACH GROUP CONSISTS OF SIXTEEN ELEMENTS IN FIVE ADJACENT COLUMNS OF A TRIANGULAR GRID, HAVING FOUR ELEMENTS IN EACH OF THE THREE INNER COLUMNS AND TWO ELEMENTS IN EACH OF THE OUTER COLUMNS. IN EACH GROUP THE ELEMENTS ARE ARRANGED TO BE SYMMETRICAL ABOUT THREE AXES HAVING A COMMON INTERSECTION AND SEPARATED BY SIXTY DEGREES. THE ELEMENTS THAT COMPRISE EACH GROUP ARE COMMONLY EXCITED AND EACH GROUP OF ELEMENTS IS EXCITED BY A DIFFEERNT BASIC EXCITATION SIGNAL. THIS ARRANGEMENT SUBSTANTIALLY REDUCES THE NUMBER OF BASIC EXCITATION SIGNALS REQUIRED AND PROVIDES EFFICIENT EXCITATION OF EACH ELEMENT WITH LOW QUANTIZATION SIDELOBES.
