microstrip transmission line hfss
Hi
I have a simple 21mm long microstrip line in HFSS(PEC) whose width,W = 0.168 mmm . I haver drawn this structure over a Ground plane (PEC) where dielectric thickness between microstrip and ground plane is 0.1mm.
When i compare the S11 results from HFSS with ADS then the ADS results are around -40 dB while HFSS results for this structure are -25 dB. I have used waveports at the ends of the microstrip with the suggested dimensions of 10*W and 8*height of dielectric.
Even after I increase my port accuracy to about 0.01 % also the results still dont match. I calculated the microstrip dimensions using linecalc from ADS.
I would reallt appreciate some help on this because I have tried everything I know and still can not make the S11 results coincident..
thanks a lot
