The aim of this work is to develop an optimized version of the Current Integration Method for reducing the computational effort required by the electromagnetic analysis of the Sardinia Radio Telescope antenna. It consists in a general purpose, fully steerable Gregorian antenna with high-efficiency operation up to 100 GHz and a very large collecting area. The optimization process is based on a non-redundant sampling representation of the induced current given in the Physical Optics approximation and can be easily extended to other reflector antenna configurations. Numerical simulations and comparisons with a commercial tool assess the efficiency of the proposed approach.
