    Abstract

    The input coupler that is used to launch the desired wave into the interaction region is an important component for a gyro-TWA. In this paper, a side-wall rectangular-to-circular coupler aiming to achieve a high coupling coefficient was designed for a W-band gyro-TWA. A broadband reflector was optimized to take the place of the cut-off waveguide to allow a much bigger beam tunnel to reduce the alignment difficulty.
