Abstract :
Based on the mode coupling theory, the design of TM01-TE11 overmoded circular waveguide mode converter geometric configuration with the different phase rematch and structure is given to obtain more acceptable geometry parameters. The regulation about the radius of the circular waveguides, curvature and frequency of bent circular waveguides and the bandwidth is obtained. The results contribute to design corresponding circular waveguide mode converter with the tight, the efficient and the wideband.
