| Abstract: | The dispersion and loss characteristics of millimeter-wave coplanar waveguides (CPWs) are analyzed by using an efficient two-dimensional finite-difference time-domain (2D FDTD) algorithm. Combined with graded mesh technique, alternating direction implicit technique and curve-fitting technique, this proposed algorithm verifies its accuracy and efficiency through an example of infinite-ground CPW. Moreover, the influence of ground-plane width on CPW's loss characteristics is analyzed. Bulk micromachined CPWs with low loss are also analyzed by the proposed algorithm. |
