Slot antenna (HFSS 15). How should i supposed to make port's excitation?

Hello everybody!

How am i supposed to do port's excitation of planar slot antenna using slot flatness only?
(HFSS 15, wave port or lumped?)


Thank you!

Welcome Foster_Ben,

I usually use wave ports, but it depends on your situation. I'm not sure what you mean by "slot flatness".

The setup you have is incorrect. A port needs to cover a tangential cross-section of the waveguide, see for example the microstrip port setup here. If you are trying to excite with, for example, a voltage source, then you need to place this source across the slot.
