In this paper, the impacts of elitism rate on the Genetic Algorithm (GA) performance for the Uniform Circular Antenna Array Pattern Synthesis Problem are investigated. For this purpose, a circular antenna array with uniformly spaced isotropic elements having identical excitation amplitudes is used as a model. Unlike the classical GA, we use a GA structure having an elitist population update approach for improved GA performance. In the elitist approach, a certain ratio of the population (i.e. the fittest individuals) is directly transferred to the next generation.
