    HFSS-antenna parameters question

    Dear All,

    I have tried to simulate a printed antenna. When I read antenna parameters, I got Directivity < 1, gain is very small and a very small radiation efficiency, which indicates an error in simulation. Then I have set the radiation box mesh to about lambda/10, I got reasonable directivity, but the values of gain and efficiency are still too low. Anyone can help? Thanks.

    Best Regards,
    Mshafee

    i think radiation box must be more than wavelenght 1/4

    Dear amu811,

    Thanks for your reply. The radiation box is lager than lambda/4, but I still get unacceptable gain and efficiency.

    Best Regardsd,
