The method of combining GRECO (graphical electromagnetic computing) to design shaped-beam reflect antenna containing single feeding source is first proposed. Shaped-beam reflect antenna in random shape is able to be designed easily by using NURBS (non-uniform rational basic spline), and the shape of a little part is able to be changed by changing the controlling points, so the phase of the reflect antenna is easily to be controlled to reach the best result. The reflect antenna is able to be divided into fragmentary parts automatically. By setting the fitting light model and light sources, the normal of the surface of the antenna is able to be gained in the case of not knowing the expression of the reflect antenna
