Analysis of Coupled Slots and Coplanar Strips on Dielectric Substrate

Asymmetrical coupled coplanar-type transmission lines with anisotropic substrates

“…These include single and coupled striplines [2] - [7], slot lines [8], and coplanar-type transmission lines [9] - [11]. The coplanar-type transmission lines (CTLs) are promising because of their easy adaptation to shunt element connections [12], [13]. The application of coupled coplanar-type transmission lines to filters and couplers was proposed by C. P. Wen [14].…”

Neural Models for Coplanar Strip Line Synthesis

“…Consequently, the approximation of quasi-static methods becomes worse as the transmission line becomes dispersive. However, it was shown by Knorr and Kuchler [7] that the CPS parameters are only slightly sensitive to variations of the frequency for CPSs with dimensions not exceeding the substrate thickness for nearly the whole microwave region. For this reason, the quasi-static methods provide simulation accuracy that is comparable with the full-wave methods for frequencies up to 20 GHz and even up to 40 GHz.…”

“…Furthermore, the structure of CPSs is very useful for radio frequency and microwave integrated circuits (MICs), especially balanced circuits due to its inherent balanced nature [1]. Various symmetric and asymmetric CPSs on single or multilayer substrates were analyzed to obtain closed-form expressions for quasi-TEM parameters using quasi-static methods [2][3][4][5][6] and to determine dispersion characteristics of CPSs with the use of full-wave methods [7][8][9]. While full-wave methods are the most accurate tools for obtaining the transmissionline characteristics and are also analytically extensive, the quasi-static methods are quite simple and lead to closed-form expressions suitable for computer-aided design (CAD) software packages, but the latter methods do not consider the dispersive nature of generic transmission lines.…”

“…Most of the conventional models for various CPSs are the analysis models [2][3][4][5][6][7][8][9] that have been used to determine the characteristic parameters of CPS structures. The synthesis models were also presented in the literature [10][11][12].…”

Multilayer Perceptron Neural Analysis of Edge Coupled and Conductor-Backed Edge Coupled Coplanar Waveguides

“…The full wave analysis is usually used to characterize such complex structure. Most of the earlier study efforts have been directed towards obtaining the design parameters by full wave numerical methods [8] or quasi-static conformal mapping methods [9]. Present analysis provides high precision in a wide frequency band and also general characteristics suitable for CAD analysis [4].…”
