Notes. In the first column the main beam efficiency, η, is presented. The second and third columns report the percentage of the power entering the near and far sidelobes, respectively (nsl and fsl): these values are directly calculated as the integral of the electric field computed with GRASP. The sum of the three beam components is presented in the fourth column. The three regions considered (main beam, near, and far sidelobes) are those defined in Sect. 1.
