In this study, we present the analysis and modeling of detailed investigation and study of different configurations of loop elements in FSS, with resonant unit cells. The elements studied are 1) Square loop, 2) Double Square loop and 3) Gridded Square loop. The simulations of microstructure are performed with full wave simulation tool CST Microwave Studio(More)
The paper addresses a CAD oriented closed-form expression for dispersive and conductor thickness based line parameters for symmetrical coplanar strip lines(CPS) on a finite-thickness dielectric substrate. Then, based on the analysis of CPS's, elliptical coplanar strip line (ECPS's) is studied. CAD oriented closed-form expression for the losses based on(More)
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(More)
The analysis and equivalent circuit modeling of square patch FSS adopting an efficient vector-fitting is proposed. The simulations of microstructure are performed with CST Microwave Studio on single-substrate for different physical parameters, angle of incidences and polarizations. Then circuit model is extracted and developed using vector-fitting tool and(More)
In this paper, we present the closed-form models of conductor thickness dependent dispersive line parameters and losses, of Asymmetric Coplanar Striplines (ACPS) on isotropic dielectric substrates. The dispersive empirical expressions for the ACPS from literature are improved to include the finite conductivity and finite conductor thickness in propagation(More)
The CAD oriented closed-form model is presented to compute frequency dependent effective relative permittivity and characteristic impedance of a slot-line with finite conductor thickness in the range 3 mum-50 mum. The model has average accuracy of about 2% against the fullwave results from different sources in the frequency range 2 GHz-60 GHz,(More)
