Multibeam MTS antenna radiation performances. (a) Simulated (blue line and red line for the IBC-MoM and full-wave results, respectively) and measured (black line) directivity pattern for the multibeam shared aperture MTS antenna at 17 GHz. The obtained beams point in the desired direction, with good cross polar discrimination and beam symmetry. (b) Measured directivity patterns at 16.75 GHz, 17 GHz and 17.25 GHz.
