Sweet spot control method of directional antenna beam

This paper proposes a control method that quickly searches for the sweet spot of multiple directional antennas. The proposed method utilizes a modified genetic algorithm, which selects a superior initial group through preprocessing in order to solve the local solution in GA. In order to verify the effectiveness of the proposed system, the simulation results of 1:1, 1:2, 1:5 directional antennas and experiment results of 1:1 directional antennas confirmed the efficiency of the proposed method. The 16bit split is 8bit, but it has similar performance as 16bit gene.
