摘　　要：设计了一种超级紧凑的、可工作于V波段及W波段的毫米波波导窗,它基于低损耗环烯烃共聚物(COC),加工成阶梯结构,放置在波导匹配段中间对称位置,并在两侧连接标准的矩形波导通道,从而具有宽带、透明、易匹配以及机械性能良好等特点。验证了该波导窗在V波段和W波段内的可行性,在回波损耗优于20 dB的情况下,在V波段工作频带为57-66 GHz,在W波段工作频带为77.8-108.25 GHz,仿真和测试结果证实其为毫米波甚至更高频带上宽带应用的理想选择。The concept of super compact millimeter wave waveguide window based on low-loss cyclic olefin copolymer(COC)at V band and W band is proposed in this work.The waveguide window is composed of a machined step-type COC dielectric,and it is placed inside modified waveguide and connected with standard rectangular waveguide at both ends.The feasibility of communication frequency band at V band and W band is verified by testing several fabricated models.With the return loss better than 20 dB,the working frequency band at V band ranges from 57 GHz to 66 GHz,and at W band ranges from 77.8 GHz to 108.25 GHz,which proves that the waveguide window is an excellent candidate for broadband applications in millimeter wave band or even higher.
