A New Curvature Based Shaped Reflector Antenna Design Methodology

A novel curvature-based shaped reflector antenna design technique using the covariance matrix adaptation evolution strategy (CMA-ES) algorithm is presented. An approach based on optimizing the profile of a curve representing a rotationally symmetric reflector is proposed. In this method, the reflector shape is optimized with few design variables and an ideal design is found within a very small number of iterations. The validity of this method is verified by an application example and its advantages are compared with a reflector surface represented using the modified Jacobi polynomials.
