Hi there,

I am new to HFSS and have been working on an antenna design. Please refer to attached pictures where I have simulated same design with exact parameters with the only difference in Delta S. First I used Delta S = 0.09 and then 0.01. I am confused about the change in resonance frequency drift due to Delta S. Can anybody explain this drift please?



 

Welcome FIqbal,

I can't see your attached images, but if you're still having problems, either your setup is not the same as your fabricated system, or the simulation isn't sufficiently converged (even at 0.01). I would try over-converging the simulation a few more passes and seeing if anything changes.

Good luck.
