question on antenna adaptation

Hi,

After designing an antenna in HFSS. How can I be shure if my design is well adapted? For exemple, if I designed a patch antenna with microstrip line of 50 ohms, should I go simulate to see if the antenna impedance is equal to 50 ohms for all the wanted frequencies ? What else should I check?

Thank you

You should look for example at your radiation and cross polarization patterns , efficiency, gain, return loss. Make sure all these and other parameter are in spec over your frequency range.
