In this paper, the authors present a method that quickly search for sweet spot of array antenna and keep it for fast speed transmission in millimeter wave. The proposed method is the Modified Genetic Algorithm (MGA) and fuzzy logic system. The MGA is used to find the approximate range as a pre-processing function. And the fuzzy logic system is used to find the exact sweet spot. They can transfer and receive a large data in millimeter wave bandwidth. Because antenna signal accounts for a few bits, influence on communication performance is little.
