“…Moreover effect of the low frequency dispersion, due to finite strip conductivity [14], on the effective relative permittivity and characteristic impedance has not been incorporated in the closedform model. The conductor and dielectric losses are computed using the Wheeler's incremental inductance rule and perturbation method [15][16][17][18][19][20]. The full-wave methods provide results on dispersive, simple and multilayered CPW, including conductor and dielectric losses.…”

Abstract-In this paper, we reformulate the quasi-static spectral domain analysis (SDA) applicable to a lossy anisotropic multilayer asymmetric coplanar waveguide (ACPW). The SDA formulation also incorporates two-layer model of a conductor thickness and the concept of effective permeability to account for the low frequency dispersion due to the magnetic field penetration in an imperfect conductor. The paper further presents the single layer reduction (SLR) formulation and circuit model to compute frequency dependent line parameters of a lossy anisotropic multilayer ACPW. The accuracy of formulation is comparable to that of the HFSS and CST, without using complex and time consuming full-wave methods. The results of CST for ε eff , Z 0 , α d , α c of multilayer ACPW, in the frequency range 1 GHz-100 GHz, deviate from results of HFSS up to 0.49%, 1.53%, 2.06% and 10.73% respectively; whereas corresponding deviations of the present SDA and SLR combined formulation are up to 1.38%, 2.09%, 3.57% and 8.87%.

“…2, the loss per unit length is plotted versus characteristic impedance for a coplanar strip transmission line with a fixed overall width of 200 µm from formulas in [4]. At impedances near the standard 50 , loss is large due to the small gap between the conductors (approximately 10 µm).…”

A new type of distributed analog phase shifter is presented that utilizes the coplanar strip transmission line topology. This transmission line has several benefits for phase shifter design, resulting in decreased physical dimensions and potentially lower losses. A prototype was constructed using thin-film barium strontium titante (BST) varactor technology. The design achieved a 49• /dB figure of merit at 10 GHz. The performance and chip area of the coplanar strip circuit are compared with designs using coplanar waveguide and synthetic lumped element transmission lines.
