Sunflower Array Antenna with Adjustable Density Taper

Figure 13

Sunflower array configuration: the elements are numbered starting from the center. In this case, 5 clockwise Fibonacci spirals appear, red line, and 8 anticlockwise, in blue line. The interval of identificative numbers between elements on the same Fibonacci spiral is always equal to the number of spirals occurring, in this figure notice 22 − 14 = 14 − 6 = 8 and 24 − 19 = 19 − 14 = 5.
