This chapter presents the characteristics of a coplanar waveguide with a lower ground plane. The lower ground plane provides mechanical strength for a thin and fragile wafer, such as GaAs, and acts as a heat sink for circuits with active devices. This configuration of the CPW is known as the conductor-backed coplanar waveguide (CBCPW). The chapter commences with expressions based on quasi-static analysis for the effective dielectric constant ?> eff and characteristic impedance Z 0 of CBCPW with and without a top metal cover. Later sections of the chapter discuss the effect of conducting lateral walls on the dominant mode of the CBCPW and the effect of lateral electric and magnetic walls on the higher order mode propagation constant. A new variant of the CBCPW, namely the channelized coplanar waveguide (CCPW), is also presented.
