The airbox in HFSS should be at lambda/4 away from the nearest the radiating structure, is this lambda referenced to the solution frequency or to the lowest frequency in the frequency sweep?
Thanks

Thanks. The document says use lambda\4 where lambda is calculated at the solution frequency, right? I am not sure about that but I will do some simulations to see if I can verify it.

yeah you are right, you have to choose lambda /4 but to be sure you have to increase as you can the distance between the structure under study and HFSS boundary to get accurate results. but i think that lambda /4 is sufficient.

your right, but you have to increase as you can the distnace between the strucutr under study and the HFSS radiation to get better results. also you have to check the kind of simulation (fast , discrete) .
