N2 - A new shaped reflector antenna design technique based on surface curvature for a continental US coverage (CONUS) beam synthesis is presented. An approach based on representing a reflector surface as a set of curves where its shape is modified by altering the curve profile. Instead of directly optimizing the curves, we first evaluate their curvature and represent it using B-spline polynomials. The spline control points are defined as optimization variables, which generates a new curvature profile at each iteration of the optimizer. From the optimized curvature profiles, the reflector surface is generated using an iterative algorithm proposed in this work. The major advantage of this work is that the surface constrains on curvature can be imposed directly in the optimizer, without the need for additional design variables as required in TICRA's POS software. The validity of this method is confirmed by an application example and its advantages are compared with a reflector surface represented using a traditional technique based on modified Jacobi polynomials.
