As the capacity of the personal computer and workstation increase rapidly, many electromagnetic simulators are widely used. In this paper, Ansoft's High Frequency Structure Simulator (HFSS), which is a commercial software product, is applied to design a mode converter operating at 35 GHz is fabricated based on the simulation results. The numerical results are in good agreement with the measured data.
