A new type of broadside-coupled CPWs (BC CPWs) is proposed using a V-shaped
microshield CPW. Closed-form expressions are presented for calculating the
quasistatic parameters of this coupled structure by using conformal mappin
g techniques. The effect of the V-shaped conductor backing on the quasistat
ic parameters and the coupling between CPWs are also discussed. Comparisons
are made between the present numerical results and the results available i
n the literature for general BC CPWs. The coupling coefficient of the prese
nt BC CPWs is shown to be significantly lower than that of general BC CPWs.
