Abstract
Based on the coupling wave theory and phase re-matching technique,a Q-band TE01-TE11circular w aveguide mode converter for transmitting high pow er microw ave has been designed and analyzed by numerical calculation and simulation. Results of 4-period and 6-period mode converter are demonstrated in this paper. The numerical calculation show that maximum conversion efficiency is 98. 82% and bandw idth is over 2. 2GHz for 4-period structure. How ever,for the6-period one,the maximum conversion efficiency is 99. 89% and bandw idth is over 1. 7GHz. It also presented the influence of the key parameters on the conversion efficiency. Simulated results from HFSS agreed w ell w ith the numerical calculation. Based on the theory and simulated results,a mode converter w as fabricated and tested. It turned out that a pure TE11mode w as abtained.
