A new analytical, CAD-oriented model for the ohmic and radiation losses of asymmetric coplanar lines in hybrid and monolithic MIC's

摘要

The paper presents analytical approximations for the conductor, dielectric and radiation losses of asym­metric coplanar waveguides. The expression for the conductor losses is obtained through an extension of Owyang and Wu's conformal mapping approach [17]; the dielectric losses are estimated according to the so-called plane-wave approach [2]; finally, the analysis of radiation losses follows Rutledge's approach [19]. Comparisons with experimental results or numerical data derived from quasi-static or full-wave approaches are performed to validate the expressions presented.
