Hi everyone, i would like to ask about the sidelobe suppression.
I'm using CST and also an antenna waveguide 8 s a lot. Anyway, i have found the frequency of my Antenna around 9.4 GHz.
But, the sidelobe really spread off.
Im using EBG to reduce it, with Taconic TLY epsilon 3.2, and also with material EBG epsilon 3.2 and tangent loss = 0.003. And also i put the PEC as a patch for the EBG and PEC too for the Ground plane. But it's very difficult to find for reducing the sidelobe.
And, i have change any position with my EBG, but it's correctly wrong. And i haven't found until now.
Do you have any idea which way i could reduce that? i'm prefer to use EBG than the other.. thank you very much.
