The direct connection of a micro strip line (MSL)to coupled lines causes a mode transformation that is
proportional to the difference in the equilibria of the lines,
which can be represented by the equilibrium mismatch model.
In this paper, we show that the mode conversion can be
accurately represented by using the staircase approximation to
represent the continuously varying unbalance coefficient as the
distance between the coupled lines and the system ground is
varied. When the coupled lines are placed perpendicular to the
system ground, full-wave calculations show that mode
conversion occurs as the distance between the coupled lines and
the system ground changes. This mode transformation is
represented using an unbalance mismatch model utilizing field
and circuit co-analysis in the commercial simulator HFSS. The
continuous variation of the unbalance factor is represented by
a staircase approximation, and by increasing the number of
steps in the staircase approximation, the peak value of the
spectrum of the DM voltage generated by the common-mode
resonance approaches the value obtained in the full-wave
calculation.
