antenna array on HFSS

[kalthoum]

Hi
please can any body help me how to realise an antenna array in hfss with 2 exitation 50hom

i have an adapted antenna in 2.45GHz frequency but when i put another same antenna the result is not adopted
plz help me

Welcome kalthoum,

I can't really tell much from your setup picture. What result are you referring to?

Welcome kalthoum,

im tolking about the s-parameters results
i want them to resonate on 2.45GHz frequency but its not the case

Do they resonate at 2.45 GHz independently?

 

[kalthoum]

the problem that in the array they dont resonate in 2.45GHz
so i changed some parameter and i found this results
is that right what i did to found a correct result?
knowing that the antenna alone resonate in 2.45Ghz

If they resonate separately at 2.45 GHz (but don't when you put them close together) then assuming the rest of your setup is the same, the coupling between the antennas is too high. This is a common problem; solutions include spacing out the antennas or attempting to reduce coupling with devices such as DGSs or EBGs.

what's the DGSs or EBGs im new in this domain
