Hi there!
I just started working with HFSS a while ago, so i´m still not totally aware of all relevant settings in my simulations.
The following problem is nagging me right now:
I am designing patch antennas that should work for a frequency range from 76-81GHz and transmit into a WR12 Waveguide. I got a few promising designs out of it and did some prototype boards based on my simulations.
The good news: So basically the S-parameters measured with the VNWA look quite like how they should, according to my simulations.
The bad news: Compared to my simulations, all measured parameters are shifted by 1.5GHz to the right hand side.
I used a solution frequency of 83GHz, since i was told i should choose a solution frequency a little higher than my frequency of interest. I´m not sure if this was the best hint...
Maximum number of passes 15 at a maximum Delta S of 0.03.
Mixed order solution and direct solver method.
I also am using the Huray surface roughness model, because otherwise i can´t simulate the losses correctly.
Any sugestions at where i am doing something wrong?
