For high-speed digital circuits a novel elevated-CPW (ECPW) structure with low loss and low dispersion is proposed and the performances are well compared with the theoretical prediction. The ECPW is designed with the aid of time domain fullwave FDTD technique and is fabricated using conventional thick-film MEMS processing. Proposed structure reveal at least 10dB lower insertion loss compared to conventional CPW geometries and effective permittivity is 4 to 6 times smaller than that of conventional CPW. Characteristic impedances and effective permittivities are given for various geometrical parameters.
