CAD models of losses for symmetric elliptical and circular cylindrical coplanar strip lines

Abstract

This article addresses a CAD-oriented closed-form expressions for dispersive and conductor thickness-based line parameters for symmetrical coplanar strip lines (CPS) on a finite-thickness dielectric substrate. The conductor and dielectric losses are also computed. The models are extended to non-planar CPS -elliptical coplanar strip line (ECPS) and cylindrical coplanar strip lines (CCPS). Finally, accurate circuit model for these structures is also presented. The results between 1 and 60 GHz are compared against the results of HFSS and Sonnet and also against the experimental results. The average deviation of the model against the experimental result is 2.06%.

Measurement of two‐layer medium dielectric property using a novel parameters model in radio frequency

“…The can be calculated as follows, 16–18 where is the relative dielectric constant of the medium around the ring electrodes. For the substrate‐embedded ring electrodes, the revised parameter can be calculated as follows 19 where is the substrate thickness of the ring electrodes. Then, substitute , into the RLCG parameters models (Equations (A1)–(A11)) for correction respectively, where , , .…”
