The procedure has been tested with different RA elements related to actual specifications. Up to 9 parameters were considered and the complete reflection coefficient matrix was accurately obtained, including cross polar reflection coefficients. Results show a good agreement between simulations carried out by the Method of Moments and the ANN model outputs at RA element level, as well as with performances of the complete RA antenna designed.}, author = {Robustillo Bay{\'o}n, Pedro and Zapata Ferrer, Juan and Encinar Garcinu{\~n}o, Jos{\'e} Antonio and Florencio, Rafael and Rodr{\'i}guez Boix, Rafael and Mosig, Juan} }
