Design step for making slot antenna in HFSS
2 likes5,523 views
This document summarizes the steps taken to simulate and analyze the radiation pattern of a slot antenna using HFSS software. The simulation involved creating a slot antenna geometry using copper material, applying a lumped port excitation from one edge to another of the slot, analyzing the return loss graph and far field pattern, and obtaining output parameters such as maximum gain, radiated power, radiation efficiency and front-to-back ratio. The conclusion is that slot antennas have applications in radar communication, cell phone base stations, and microwave sources based on analyzing the simulation results.
