    How to assign the port for CPW Antenna_HFSS

    Re: CPW Antenna_HFSS hi mustafa here is ur design after excitation Notes : i notice that u use just 6 pass which cause no convergency for solution try to use more than 6 pass and also try to use smaller air box for radiation boundary to save ur time best regards

    need help in HFSS meshing

    dear YoungEng thnks for ur help i was try to use waveports and also consider the appropriate size of port according to manual but i notice that lumped port is more easier for this problem because as i change dimensions of waveport (according to range in manual) it gives me different reult for...
