摘　　要：共面带线具有平行结构,优良的线性发散的传输特性,对基片的厚度不是很敏感,可广泛运用于单平面微波电路如检波器、滤波器、天线和光电子设备等的设计。目前,国内外对于共面带线滤波器的研究不多,采用微带线滤波器的设计原理,对集中参数低通滤波器的设计方法进行了研究,设计一种集中参数的低通滤波器,并通过试验和仿真进行验证,表明该方法对共面带线低通滤波器的设计具有很大的借鉴意义。Coplanar Stripline （CPS） has parallel structure,good linearly emanative transfer characteristic,and isn＇t sensitive to thickness of substrate,and it can be widely used for designing uniplanar microwave circuit such as detector, filter,antenna and photoelectron devices, by now,little is studied on CPS filters in the world, by adopting the design theory of microstrip filter,the design method for CPS lowpass filter of lumped parameters is studied,and a practical filter is devised,the results of experiment and simulating validates its feasibility and correctness,shows that this methord is useful to the design of CPS lowpass filter.
