    HFSS error: Adaptive solution setup, process abc3d : subprocess "wave" encountered

    HFSS error: Adaptive solution setup, process abc3d : subprocess "wave" encountered I have the following error, but I don't understand it : [error] Adaptive solution setup, process abc3d : subprocess "wave" encountered error in zeta computation. (6:40 mai 17, 2005) If anyone can help me ...

    What kind of polarization does this microstrip patch antenna have?

    Re: antenna pls help You have E_left = E_right, thus the polarization is purely linear

    Help me with polarization using a PIFA by simulating in HFSS

    Polarization I am trying to do a circular polarization with a PIFA, by simulating under HFSS. But I tried different designs but none of them satisfy this constraint. If you have any ideas please answer me. Thanks a lot Ludovic

    Help me interpret LHC and RHC of a patch antenna

    Re: antenna parameter Hi Danesh, By looking the E_RHC field and E_LHC field, you can determine which type of polarization you have. In your case you have circular polarization because the E_RCH field level is higher than the other component. As you can see, the axial will near 0 dB when the...

    What is exactly Gaintotal, GainLHCP and GainRHCP for HFSS?

    I want to know what is exactly Gaintotal, GainLHCP, GainRHCP for HFSS. And for a linear polarization, which result are we suppose to have for GainLHCP and for GainRHCP ? Thanks for your answers, Ludovic

    Polarizaation of PIFA

    Do you know if it's possible to do a circular polarization with a PIFA ? Because I want to do a very small GPS antenna, but I have not to much space. If you have interesting ideas, tell me about it. Thanks a lot Ludovic
