Generally, you would be using 50 ohms impedance connector for RF applications. Same can be achieved using the ports inside Ansys HFSS. These are provided for user convenience in simplifying the model. You can go through this Ansys Innovation Course for more details on the ports - Ansys HFSS Port Types - ANSYS Innovation Courses.

For the case of microstrip traces, there are specific guidelines when using a waveport. This is required to capture the fringing fields. Please go through "wave port size" section of the Ansys HFSS Help document.

All the very best,
