Hi,
When we design an antenna in CST or HFSS, we define "waveport" at the feeding terminal with a "rectangular cross section".
But practically we feed the antenna by SMA connector connected with a 50 ohm coax.
My question is why these EM software use "waveport"? Why don't we just place a SMA connector in CST/HFSS and simulate?
I read about it in documentation that cross section of waveport is regarded as a cross section of an infinite rectangular waveguide connected to antenna but in practice we are NOT feeding the antenna with that rectangular waveguide. So, why assuming this?
Please do not refer me any CST/HFSS documentation because I have read them and got lost in the middle of their professionally-curtailed language presentation.
