摘　　要：基于电磁理论计算，发现在Ｗ频段存在环行方向一致的双高阶结谐振模，两模相互邻近，可以用来制成双频环行器，也可以调整环行器参数使两模部分重迭，得到宽带特性．本文给出的实验结果验证了理论预言．It was found that there are dual higher order modes which have the same circulation direction at W band based on the calculation of boundary value of electromagnetic field. The dual modes are close to each other. They can be used to realize dual frequency circulator,or to get broadband performance by partially staggering them. Experiments given in this paper verified the theoretical prediction. A broadband waveguide junction circulator at W band was developed. The performance of 8 GHz bandwidth with 18 dB isolation was obtained by staggering the dual higher order modes.
