Abstract

The V-shaped microshield coupled parallel coplanar waveguides, a new type of the coupled parallel coplanar waveguide (CP CPW), is proposed. Closed-form expressions are presented for calculating the quasistatic parameters of this coupled structure by using conformal-mapping techniques. The effect of the V-shaped conductor backing on the coupling between CPWs is also discussed. Comparisons are made between the present numerical results and the spectral-domain method results available in the literature for a conventional CP CPW. In addition, the coupling coefficient of the present coupled CPW is shown to be significantly lower than that of a coupled parallel CPW
