hi,
while simulating a dual band PIFA for the 900 and 1800 GSM bands in HFSS, i faced this problem that when i change the accuracy level slightly , the result say return loss is changing considerably in the frequency range.how do i know which acuracy level gives the best and most realistic result if i fabricate it.then if i take a very accurate simulation result it is varying very much compared to the IE3D results . wat should i do.
somebody plz do advice!!

Dear abhi_kolkata:
Try forcing HFSS to take more adaptive passes. Sometimes it shows error convergence when error convergence has not really been achieved. Sometimes, you get two adaptive passes that happen to have about the same amount of error, which can fool the convergence criteria tester to think you have achieved convergence. In these cases, if you push the mesher to take more passes, you will sometimes see more pass-to-pass error.
