Abstract
This paper proposed an X-band compact efficient rectangular waveguide TE10-circular waveguide TE01 mode converter and conducted its structure design, theoretical analysis, numerical simulation, and experimental research. This mode converter is composed of a rectangular waveguide TE10–TE20 mode converter and a rectangular waveguide TE20-circular waveguide TE01 mode converter. In the design of the rectangular waveguide TE20-circular waveguide TE01 mode converter, a rectangular waveguide step is used to counteract the microwave reflection due to the discontinuity of the rectangular–circular waveguide connection, and two choke slots are involved to suppress the TE21 mode in the circular waveguide by cutting off the axial component of its surface current on the waveguide wall, so as to improve the TE01 mode conversion efficiency. The simulation results show that the reflection coefficient of the mode converter is less than 5% and the TE01 mode conversion efficiency is about 98.4% at the operation frequency of 9.3 GHz. The bandwidth with a transmission coefficient greater than 98% is about 200 MHz. The back-to-back experimental system is demonstrated, and the experimental results show that the measured TE01 mode conversion efficiency is about 98.2%, which is consistent with the simulation result.
