Abstract

An optimized linear fractal-random array with 848 elements and a side-lobe level of approximately 20 dB was investigated by applying the genetic algorithm approach. The radiation pattern and geometrical layout of the antenna array were also analyzed. The fitness function for the genetic algorithm was found to be the sum of the maximum side-lobe level and a window function. Three separate mitosis processes were used to double the number of generators in each array. These mitosis processes resulted in a staircase pattern.
