Synthesis of Antenna Array by Complex-valued Genetic Algorithm


Yan Wang, Shangce Gao, Hang Yu, Zheng Tang


Vol. 11  No. 1  pp. 91-96


The synthesis of the radiation pattern of linear antenna arrays is an interesting problem in radiating systems. A complex-valued genetic algorithm (GA) for optimization of beam forming in linear array antennas is presented in this paper. Unlike conventional GA using binary coding, this method directly represents the array excitation weighting vectors as complex number chromosomes and improves genetic operator methods based on the complex-valued encoding. The algorithm enhances searching efficiency greatly, and avoids effectively premature convergence. Numerical results are presented to illustrate the advantages of the proposed technique over conventional pattern synthesis methods.
