摘要
介绍了一种由4个宽带波导魔T级联而成的X波段宽带和差网络。采用一种改善宽带波导魔T频率特性的新颖方法,在波导魔T的E面上级联变换段和H臂上增加电感膜片,得到40%带宽内优异电性能。并通过理论分析、三维电磁仿真构造了具有同样优异性能的宽带波导和差网络。最后,给出了波导魔T和波导和差网络的实测结果。
A novel waveguide sum-and-difference network at X band which is composed of four waveguide magic T with broad bandwidth is presented.A method of improving bandwidth is introduced in this paper.The method is fulfilled by adding longitudinal section step to the E-plane and slices to the H-plane,getting an excellent performance magic T.The waveguide sum-and-difference network which exhibits a large bandwidth of 40% is proposed,explained by theoretical analysis,validated by full-wave simulation,and demonstrated by experiments.Finally,the results of experiments of magic T and waveguide sum-and-difference network is given at the same time.
