We present application of EM-simulators for studying characteristics of line parameters of different planar transmission lines. The main objective is to realize different planar transmission lines in EM-simulators and compare their line parameters (de-embedded and non de-embedded) against results from experiments and analytical models for wide range of data, which further proves the validity of the...
The paper addresses a CAD oriented closed-form expressions for the losses based on stopping distance for different configurations of elliptical CPW (ECPW) and cylindrical CPW (CCPW) on a finite-thickness multilayered dielectric substrates. The analysis of the structures has been done using conformal mapping and SLR technique. Comparisons with 3D-EM simulators are presented to validate the expressions...
The paper addresses a CAD oriented closed-form expressions for the losses based on stopping distance for semi-ellipsoidal coplanar waveguide (SECPW) and semi-circular cylindrical coplanar waveguide (SCCPW) on a finite-thickness dielectric substrate. The analysis of the structures has been done using conformal mapping technique. The expressions are simple and accurate for microwave circuit designs...
The theoretical and experimentally extracted closed-form models of stopping distance are presented that provides the CAD oriented simple model to compute conductor loss of CPW with average deviation within 5.4% against the experimental results from three independent sources. Whereas the models of Holloway and Kuester has 14.6% error and model of Ponchak et al. has 17.1% error, against same sets of...
We present closed-form expression to compute the conductor loss of the conductor backed asymmetric coplanar waveguide (ACPW). The expression is based on the perturbation method and the concept of the stopping distance. The effect of the presence of the conductor backing on the loss computation is discussed. Comparisons with the method of moment based software LINPAR are presented to validate the expressions...
