[其它]A Broadband Series Power Divider Using Zero-Degree Metamaterial Phase-Shifting Lines

Abstract—A metamaterial 1:4 series power divider that provides 4Uy>#IL  
equal power split to all four output ports over a large bandwidth is <"|<)BGeI  
presented, which can be extended to an arbitrary number of output rgvc5p  
ports. The divider comprises four nonradiating metamaterial lines q$2taG}  
in series, incurring a zero insertion phase over a large bandwidth, *,*:6^t  
while simultaneously maintaining a compact length of 0 8. Compared =iN_Ug+  
to a series power divider employing conventional one-wavelength M(]|}%  
long meandered transmission lines to provide in-phase signals }${ZI  
at the output ports, the metamaterial divider provides a 165% ;KZ2L~ THG  
increase in the input return-loss bandwidth and a 155% and 154% ZWe$(?  
increase in the through-power bandwidth to ports 3 and 4, respectively. !.GY~f<d$  
In addition, the metamaterial divider is significantly more \#oV<MR  
compact, occupying only 2.6% of the area that the transmission XJ1nhE

thanks 4 sharing

可那看看看看看看看看困难

功分器是一种常用的器件

好感谢 8eNGPuoL)  
。。。。。。。。。。。。。。

下来看看，谢谢

好，好，好。。。。。。。。。。。。

正好需要这个东西啊
