Description
Summary:This paper presents an efficient design method based on genetic algorithm and design results for Ka band reconfigurable beam antenna composed of an array-fed reflector. The effective cost functions for the contoured beam and the boosted beams were used to find the best solution. During the optimization, it was confirmed that the average cost and the best cost were converged. The contoured beam antenna is designed with the gain ripple less than 3 dB over the coverage. The boost level greater than 7 dB for Seoul area is obtained.
