摘　　要：提出了一种新型的基于左手传输线的威尔金森功分器,该器件利用左手传输线具有非线性色散的特性,使用L-C元件构成的-λ/4左手传输线来取代传统功分器的右手传输线构成分支臂。仿真和实验结果表明该新型的功分器能有效增加器件的隔离带宽,缩小器件的尺寸。同时仿真与实验测试结果很好的一致。The present paper proposed a novel design of a Wilkinson power divider, which utilized the nonlinear dispersion characteristic of the left-handed transmission line （LHTL）. The proposed device was fabricated by using the lumped L-C - λ/4 LHTLs, instead of the conventional TLs to implement branch arms, which effectively increased the bandwidth of return loss and isolation, and reduced the whole size of the device as well. The measured results show good consistent with the simulation results.
