Hi everyone,
TO get a correct waveport size, I run "PortOnly" simulation in HFSS. But there are two optional port sizes which seem both correct. Can you please tell me which one is more correct/better?
(1) Port-Height=2.6mm => Port-Width=3.79mm;
(2) Port-Height=3.5mm => Port-Width=3.76mm.
The employed substrate is Rogers6002, with 0.508-mm thickness. The designed bandwidth is from 29.26 to 35.56GHz. The center freq is 32.4GHz. So the microstrip line width is 1.362mm (from ADS). I need a port size which allow fundamental mode up to 36GHz.
The other information are: 5*PortH=2.54mm; 10*PortH=5.080mm;
5*PortW=6.810mm; 10*PortW=13.62mm
Thank you very much.
