LOOP Antenna Simulation

I designed a loop antenna and want it to be simulated using HFSS. Please can anyone guide me how to set the parameters in HFSS. The antenna is an rectangular loop and want to plot the radiation pattern and the gain. Please let me know the steps or any tutorial that will guide me to simulate the antenna. looking forward for your help.
Thanking in advance,
