Theoretical analysis on structures of pill?box input window and double?window output window for W?band gyro?TWT,working in TE01 mode,is conducted according to the actual engineering demand. Sapphire was chosen as the window mate?rial. Simulation and optimization were performed with HFSS. The simulation result shows that the bandwidth of both the two win?dows(input and output window)meets the demand of S11<-20 dB and S21>-0.08 dB,and their bandwidthes are 7.4 GHz and 9.1 GHz respectively. Compared with the conventional window,the bandwidth of the improved window increased nearly 3.4 GHz.
