Hello All Hope to be fine , can you please answer my question.
how can i excitation rectangular loop antenna in the HFSS?
How can find dimision for radiation box?
how can i find f0 for this antenna?
i attach my HFSS design for help you.
In terms of excitation I think you want a lumped port. Perhaps a wave port would work? Someone correct me there if I'm wrong. As for your radiation box, I believe you want a box that extends at least lambda/4 from the edges of your antenna and then assign PML boundaries. Good luck.
Dear Mohammad Amir
In wire antenna you should use the lumped element port to connect both end-side of the antenna.
Usually you should have at least a lambda/4 space corresponding to the minimum frequency, around the structure. Be aware of enlarging the radiation box which causes the long simulation time!
At last, after simulation you could plot the s11 parameter to know about the resonant frequency of antenna
good luck

You can use a lumped port to connect both ends of the loop. However, the most accurate simulation setup is the one that best represents the measurement setup.
Hello,
Please make use of a lumped port by connecting the two ends with a small plate of no material......
Dimensions of the radiation box are around lambda/4 from the each and every end point of your design to all sides .......
