Design of a W-band low loss TE10-TE01 mode converter
This paper presents the design of a W-band low loss TE10-TE01 mode converter, which is mainly used in the input system of W-band gyro-TWT. Based on the design, the 3-D model has been optimized and simulated in ANSOFT HFSS. A TE10-TE01 broad band mode converter with a loss of less than 0.14 dB, maximum VSWR of 1.388, and a band width of 10GHz was obtained through the simulation. Then a pair of manufactured mode converters was tested in the experiment, and the loss was about 1 dB.
