Implementation of Generalized Transmission-Line Equations to Transmission Line Parameter ExtractionAbstract
It is usually ignored that
the transmission line parameters
extracted by conventional transmission
line equations are variable with the
internal impedance of excitation source
and the loading of the line. To obtain
the correct parameters, the match for
both excitation and loading has to be
applied. Problem is that exact matches
for some extreme cases are not easy to
realize. To solve this problem, in this
paper, generalized transmission-line
equations are implemented to the
transmission-line parameter extraction
with the cooperation of full-wave solver
Zeland IE3D. The parameters extracted
by the generalized transmission line
equations are invariant to both excitation
and loading. Except for this, the local
radiation parameters generated from the
transmission line discontinuities can
also be found
