Design and Analysis of 94 GHz TE_(02)-TE_(11) Mode Converter Sequence

This paper presents design and analysis of TE02-TE01-TE11 mode converter sequence.The computations are based on coupled mode theory.By numerical analysis and optimization,a converter sequence of high performance is acquired.The convert efficiency of TE02-TE01and TE01-TE11 converter are approximately 96.3% and 94.1% at 94 GHz,respectively,with the corresponding bandwidth reaches 4 GHz(above 95%) and 2 GHz(above 90%),respectively.Simulations using HFSS are accomplished,and the result shows high consistence with the design data.
