Abstract

A novel method of designing array-fed reflector antenna for spatial power combining is proposed. The reflector is modeled using NURBS surface. Genetic algorithm is used to optimize the shape of surface and get the maximum power combining efficiency by adjusting the positions of NURBS surface´s control points properly. The optimal positions of the control points can be attained. Besides, we also study the influence of NURBS surface´s degree on shape modification. Numerical results are presented showing the validity of the method and the antenna designed with this method can combine the microwave power in the desired direction efficiently.
