“…It is applied widely in array processing, as well as in the analysis and design of patterns. Recently, a genetic algorithm optimization is used to reduce the sidelobe level for linear array antennas [11,12,18,3,16,4,15]. Genetic algorithm is used for optimizing the array element position for planar array antenna [17,2], the array weighting for difference pattern antenna [8], and the array placement for circular array antenna [9].…”
