IE3D radiation resistance of an antenna

Hi,
is there a possibility to derive the radiation resistance of an antenna in IE3D??

Best regards

Of course，it's possible.
you can read it from IE3D directly.

Where exactly?? Cause I couldn't find it. And the help is quite poor.

thx

In fact, you can just display the input impedance for it. It will tell you the Zin = R + j X. You may argue the R includes the radiation and dissipated loss. However, for a full-wave EM simulator. all losses are the same. You can only access the R = Re(Zin).
