Hi! I am trying to find characteristic modes of a unit cell of LWA. I have also tried to simulate it in CST (I can see radiating modes of a structure in CST), but now I am trying it in FEKO with substrate and infinite ground plane to simulate complete structure. But after all efforts I am still not being able to plot modes in FEKO, it is not giving me correct modes and currents . Can you please check my design in attached file?
Thank you so much
