I am watching out of the gain. So far, my education makes me believe that negative gain is not so desirable for an antenna and that's why I am varying the feed point to ensure I get a positive gain. Thank you for your recommendation of extracting input impedance from the return losses.
Please, I need some help to understand the result of my S11 result for the simulation of a second-order iteration Koch fractal antenna in HFSS. I have attached the S-parameter result and the 3D polar plot that shows the antenna gain. I am using a coaxial probe feed for the excitation

Please, can someone help me with some clarification? What is the difference between these two solution types in Ansys HFSS: (Driven Modal) and (Modal Network). I am new to the software and using the Ansys Electronics Desktop Student 2023 R2. However, I discovered that in most of the tutorials I...
