For a hypothetical, 150-micron (6-mil), 50Ω FR-4 stripline, Figure 1 illustrates the relative influence of skin-effect and dielectric losses on the characteristic impedance of a lossy transmission ...
On the ZY chart, the impedance Smith chart is overlaid by its admittance Smith chart, which is created by rotating the impedance chart by 180 degrees. Addition of components in series moves the ...
The Smith chart appeared in 1939 (Ref. 1) as a graph-based method of simplifying the complex math (that is, calculations involving variables of the form x + jy) needed to describe the characteristics ...
