摘　　要：设计了一种新型的微带转共面带状线(Coplanar StripLine以下简称CPS)的巴伦结构。它可以应用于多种常用的介质板上,具有结构紧凑、超宽带、低损耗的特点。制作了一个两端为50Ω微带线的背靠背电路,测试得插入损耗(S21)>-1dB、回波损耗(S11)<-15dB的带宽为2.7GHz～7.3GHz,S21>-4dB、S11<-10dB的带宽为1.4GHz～15.6GHz。A novel MS（microstrip）-CPS（Coplanar Stripline） Balun Transition has been developed. The transition is applicable to substrates with many common dielectric constant. Compact size. Ultra-wideband. low-loss？are its notable characteristics . the two back-to-back transitions with the same 50 microstrip feed lines are fabricated and tested. Measured results exhibit an insertion loss （S12）〉 -I dB and a return loss （Sll）〈 -15 dB over a bandwidth from 2,7 GHz to 7.3 GHz ,an S12〉 -4 dB and SII〈 -10 dB over a bandwidth from 1.4GHz to 15.6 GHz .
