A High Efficiency TE_(01)-TE_(11) Mode Converter

摘要

A high efficiency TE_(01)-TE_(11) mode converter is designed and analyzed based on coupled wave theory. The optimal configurations of a three-period converter is obtained to realize the optimal conversion at 30.5 GHz. The simulation results show that a conversion efficiency of up to 99.85% is got with a bandwidth of 4.4% over a converting efficiency of 95%, and the TE_(11) mode purity is also up to 99.9% at the output port.
