3D Polar Plot in HFSS (the settings)

Hi all,

can someone look at my 3D polar plot...why got hollow in my radiation plot?

i'm using hfss for reflectarray antenna.

TIA

Check the range of theta and phi in your Farfield setup (in the Radiation sphere dialog box)

You have not used the full range of phi values.

thanks SO MUCH jeeudr..u are right! i must set the phi value from 0 to 360 with step size = 2 now i got what i want :)
