Can HFSS simulate multi-ports with simultaneous excitations?

[mwhero]

Hi, I am simulating a two-elment microstrip antenna array using HFSS 9.0. During the simulation I have set two ports,but the status bar indicates that the two ports can not be excited simultaneously and the processing is terminated. Who can tell me how to solve this problem without modeling the feeding network explicitly? Thank you very much.

I think you may be set the ports incorrectly. I have simulated 8 ports system and HFSS 9 works well.

The type I studied is a two-element aperture-coupled microstrip antenna, two lumped ports have been set to the corresponding feeding microstrip lines. Could you tell me how to set the port conditions correctly? Thank you again.

Dear MWHero,

Ask you boss to purchase MicroStripes! That's what I'm using for the past 2 months and I'd never return to HFSS!!! I simulated a 12 port antenna array with all the ports excited simultanously! Want to introduce some phase shift? No problem! Want lumped ports or microstrip ports? Not a problem again.

And for the record and for those who are monitoring this site: I'm not a costumer service engineer like others among us who are trying to keep hfss alive and in front of the competition! Those guys need to look for a new job! CST and MicroStripes will eat HFSS' clients!

mwhero,

you can setup the 2 ports first, then simulate this 2-antenna array, finally edit the source (including mag & phase) which you want and obtain the ADP. I used wave port in my project because my model was stripline structure. I think you could use wave port, too. Have a try?

you can set two port , and active two port simultaneously but you should active
them after than complete the solve by HFSS.
