In HFSS, if we set solution type as driven modal; the lumped port is defined as one sheet and we add the integration line. But in driven terminal the sheet is defined as port and we just need to set one neighboring PEC as reference.
Driven Model:
Calculates the modal-based S-parameters. The S-matrix solutions will be expressed in terms of the incident and reflected powers of waveguide modes
Driven Terminal:
calculates the terminal-based S-parameters of multi-conductor transmission line ports. The S-matrix solutions will be expressed in terms of terminal voltages and currents.
so if we excite a microstrip line with one these 2 ports, which is better?
what about antenna?
and most importantly what is their differences?
the size of port or ... ?
If your exitation port out side the radiation box always use deiven terminal.
if it is inside then use driven model. for patch antenna it is always driven model. and for wave guide like horn antenna it is driven terminal.
hi all, am enjoyed in learning HFSS in 20 days so. could you please explain how how to assign IE to design like parabolic reflector with horn as feed in HFSS 15 version.
