room simualation in hfss
Hi,
I'm working on an UWB patch antenna, I have performed my structure using hfss but when I realise my structure I find it very different to practice I don't understand the real cause of this difference especially in the lower band so I repeat the simulation with CST to compare and I find that CST give me more better result than hfss and near to the measure. I have simulated the different scenario in hfss (lumped port, wave port with different dimension, design of the SMA connector, interpolate, change of central frequency) but always the same result. I attach the curves comparing this different results and I wait for your help because I can’t understand why hfss give me this difference??? What can I do to have the same result???
Thank you,
Best regards,
