Characteristic mode analysis of Unit Cell

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

    I have also tried it with the ground plane of the same size as the TOP PEC layer, still not getting any results

    Are you sure you want to solve a model of size of around 17 mm from 16 to 23 Hz?

    Did you perhaps mean GHz? If so, then use 16e9 to 23e9 for the frequency.

    Thank you so much. I think issue resolved :D/emoticons/default_biggrin.png' srcset='/emoticons/biggrin@2x.png 2x' title=':D' width='20' />
