The optimization of a flat-top pattern of planar 2-D array antenna is proposed in this paper. The shaped-beam planar array is employed to be an element of very large array for the deep space detection. A conventional genetic algorithm is chosen for the optimization. However, the synthesis of a flat-top shaped beam using a planar 2-D array is difficult(More)
A novel method of plane wave synthesis is presented with the application of the least square method in the plane wave synthesis technique. With the rectangular planar array made up of the half-wavelength dipole elements as the theoretical model of plane wave synthesis, the novel method is used to seek optimum amplitude and phase distribution of array(More)
