Abstract: Coplanar waveguides (CPWs) on substrates backed by a conducting ground plane are finding increasing application in the fabrication of GaAs monolithic microwave integrated circuits (MMICs) because their lateral dimensions can be conveniently tapered from microstrip line widths down to IC bonding pad dimensions to provide the desired impedance. In this paper, the effect of the conducting enclosure on the characteristic impedance of the CPW is studied by the finite element method (FEM), and the resulting characteristic impedances for alumina ( epsilon //R equals equals 9. 9) and GaAs ( epsilon //R equals equals 12. 9) substrates as a function of enclosure dimensions and substrate thickness are presented.
