That's why I am asking about it, because I do not know how to find it from the graph

I already checked, most of them are using the transfer function method which is very long process if I want to do it for many graphs
May I know how you find it -19dB?

Can you be more precise please?, or if you have links explaining that would you provide them please.
Hi
I have designed a Chebyshev microstrip bandpass filter for frequency range (27.5 - 31.2)GHz and according to my specifications the stopband attenuation should be higher than 30 dB. May I know how to obtain that from the graph?
I think you miss read my question. I have designed the filter for different substrates, like FR4, Roger Duroid 5880, ect, and i want to combine these results in one graph, like one graph for insertion loss for all the substrate materials

I have designed a microstrip bandpass filter in ADS, and I have designed the filter for different substrate materials and I would like to add all the simulation results for the different substrates in one graph so i can have a better comparison between them. I have looked and found that ADS does...
I have gone through all your comments, and Yes I already know that my design is incorrect and not logical at all. However, what is the most suitable way to overcome this problem since my project is only for simulation, and I am not required to fabricate it?. Should I take Niki's advice and...
I'm designing a Butterworth microstrip bandpass filter, and I have calculated its order by using Bilinear method and I got it as 31st order. The frequency band is from 27.5 GHz to 31.225 GHz, and I have tried to simulate it on ADS by using cascading method (added 10th order 3 times with 1st...
Yes there is 0.6mm but its size is small 10x15 cm

I am still figuring out how to resolve the physical parameters issue, since volker@muehlhaus said they do not make sense
Yeah, I know FR4 is not a good material, and I prefer to chose roger duroid instead, but FR4 is the only option I have, and I am not expecting a good performance as the simulation results
Yes, the tangent loss has already been considered. Thanks for the reminder :)
Yes, I got your point, I have to replace MCLIN with MCFIL, but my point is, should I use the same physical parameters of MCLIN that have been calculated by ADS before optimization?
Yes i am using FR4 with 1mm thickness since it's the only available material here in Malaysia.
Here is the EM simulation for the design
Regarding for the MCLIN limitation, I think yeah it cannot be used for my design since Fc= 29.36 GHz
I was looking in MCFIL limitation and it is similar to...
Actually the pervious parameters are much better than the one in the figure which they have been obtained from the optimization. I checked about the limitation values, but I did not find anything about it. So what is your suggestion here?
I have seen many journals, but no one has mentioned...
I did not use lumped elements, since they cannot be used for high frequency

Can you explain something?, and how did you get these values??
