Full wave analysis of tapered microstrip lines using the conformal grids FD-TD method

A three-dimensional full-wave analysis of tapered microstrip lines is carried out in the time domain. The method used is the conformal-grid FD-TD (finite-difference-time-domain) method. Computed results are compared with experimental ones and those obtained by the finite-element method. The results agree well. As a result, it is shown that the propagation characteristics are very different from those obtained through two-dimensional modeling.<
