Erraneous Results for Lossy Substrates in HFSS -CPW simulations ?

    • Jalaj Chaturvedi

      For one substrate (non-lossy), it is giving me satisfactory reults while for lossy substrates, the s parameters are very weird and far from real.
      Can you please help me out on this. Is there anything extra that needs to be done to account for lossy substrates ?

      Hi Jalaj,

      Could you please share some additional details :

      What type of simulation you are doing Antenna or CPW Line ?

      What is frequency of application and sweep frequency ?

      What type of Port (Lumped or Waveport), is used in Simulation

      Having screenshot of the results comparsion and model with excitation/port is appreciated.

      Thanks,
