Hi,
I'm trying to simulate S-parameters of a microstrip low-pass filter using HFSS. I've played around with other designs but I'm having trouble with this one in particular. I believe it has to do with the dimensions (roughly 50mmx50umx100nm). I imagine it has something to do with the mesh not adapting properly in all dimensions. I tried changing the maximum delta S parameter which appears to change the mesh size. However, it seems like I'm getting wildly different results from changing the mesh size.
I've also tried shortening the length and width to the order of microns to make the dimensions a little more consistent. The mesh looks much better and I think the solutions are trustworthy, but slightly varying one of these dimensions reveals that the solutions are not directly scalable.
Does anyone have any suggestions as to how I can simulate reliably using the original dimensions?
