Analytical description of metal loss in finite-difference transmission-line analysis

Performance limitations of passive UHF RFID systems

“…Section 3 is devoted for the achievement of the correctness of analytical expressions obtained in this article. A beneficial comparison is also undertaken with those of the other analysis methods reported elsewhere [7,8,10,13]. The variation of attenuation constant, effective dielectric constant and characteristic impedance of the line according to the change in dimensional parameters are shown.…”

“…In addition, ␣ increases considerably with increasing frequency and D 2 as indicated in Figure 3(b). Also, for D 2 ϭ 200 m and S 2 ϭ 20 m values GA CPW is become equivalent to the structure modeled in [10]. In [10], attenuation constant of the transmission line has been analyzed via using three different methods: namely mode-matching, finite difference frequency domain (FDFD) and analytical FDFD methods.…”

In [10], attenuation constant of the transmission line has been analyzed via using three different methods: namely mode-matching, finite difference frequency domain (FDFD) and analytical FDFD methods. It is found that they all were in good agreement with our results of analysis method undertaken in this study as shown in Figures 3(a) and 3(b).…”
