The frequency dependence of the characteristic impedance of microstrip lines has been investigated by many authors using 3D‐FDTD formulations. In the present letter, a two‐dimensional FDTD scheme is used to calculate both the propagation constant and the characteristic impedance of the fundamental quasi‐TEM mode in a microstrip which, in fact, is a hybrid mode. Because of the substantial reduction of computer resources required for the calculations, this method can be used as a design tool. © 1997 John Wiley & Sons, Inc.
