摘要
通过对弯波导拐角位移的精确计算以及对弯波导散射损耗和弯曲损耗的分析。设计一款应用于8.2GHz、9.7GHz、11.2GHz频段的多频化、低损耗的弯曲波导。仿真结果表明,该波导在8.2GHz、9.7GHz、11.2GHz这三个频率的回波损耗达到-25d B以下,插入损耗在0.2d B以内,满足设计要求。
Through the calculation of displacement of curved waveguide corner and the analysis of the scattering loss and winding loss.a novel multiband and low loss of bend waveguide covering 8.2GHz,9.7GHz and 11.2GHzis proposed in this letter.The simulation results show that the returnloss at below 25 d B are 8.2GHz,9.7GHz and 11.2GHz. and the insertion loss within0.2 d B.The simulation results meetthe design requirements for multiband and low loss.
