antenna directivity profile

Hello, how can I plot the directivity of an antenna in HFSS in dBi (relative to an isotropic antenna) since in the plot window I can only select dB for the measurement unit?

Thank you

Hi

The "dB" you can select is in dBi.

Regards

Are you sure, because I have values of -3dB and I don't know how to interpret that?

Hi

Well....I do not know your antenna, but it is possible to have negative gain.
What sort of antenna are we talking about?

it is a printed half-wave dipole with an integrated balun
