Abstract :
Since the series fed microstrip patch array antenna has low feeding loss, it is especially effective for the millimeter wave application. In order to realize an array antenna with a high gain, low sidelobe level, and low VSWR, we have optimized the width and element spacing for each patch antenna by the parato genetic algorithm. As for such an evolution method as genetic algorithm, the calculation load is enormous. In this paper, to reduce the load, these parameters are optimized by a coarse mesh. After optimization, we check the performance by a fine mesh. By numerical simulation of a planar array, we confirmed the effectiveness of the proposed method.
