摘要：

Slow wave coplanar transmission lilies (S-CPW) based on conventional coplanar CPW transmission lines with a floating patterned ground plane arc good candidates for the integration of distributed RF circuits for front-end modules. They offer high quality factors when compared to com,entional coplanar transinission lilies. In this article, guidelines are carried out for the design of such transmission lines. Simulations are first compared to already published measurements thus validating the simulation method used throughout the article. Next, considering a standard 0.35 mu m CMOS process, design guidelines are presented in order to determine the characteristic impedance, the phase velocity, and the dielectric effective constant of the S-CPW transmission lilies, along with the attenuation loss and the quality factor. The effects of CPW dimensions, the floating strips duty cycle, the floating strip width, and the ground plane width are studied, and an optiamized 50-Omega transmission line is designed.
