How to excite Yagi Uda antenna in HFSS?

Hi,

I guess you should use a lumped feed.

Draw a "face" in between the gap and assigne an excitation boundary condition.

Is preety much the same for all EM-Simulators.

F.

what do you mean by drawing a 'face'?Sorry, Im still new at hfss

u send me the structure file or paper i will draw the project and send it back to you
