Abstract :
Dispersion and radiation properties of the conductor-backed CPW are studied. A frequency-domain finite-difference method using the PML absorbing boundary condition is used. The different types of higher-order modes are identified and design rules to avoid parasitic effects are given. Radiation is found to be considerably smaller than for infinite ground width.
