This paper proposes a broadband compact and oversized TE01 hexa-polar waveguide bend in Ka-band. Due to the introducing of hexa-polar waveguide, the degeneration between the TE01 mode and TM11 mode is destroyed. The influence of the relative perturbation on the coupling capacity is analyzed and the waveguide bend is designed based on the analysis results. The results prove that it achieves a transmission bandwidth with 9.6 GHz at the 95% level for TE01 mode (relative bandwidth is over 30%).
