The finite‐difference time‐domain method (FDTD) is widely applied for the analysis of various microwave circuits. In this letter, an important aspect of an internal resistive source modeling is emphasized for reducing the number of time steps required for the FDTD calculation to converge, especially for transient excitation. A CPW folded‐slot antenna and CPS bandstop filter are chosen as complex structures to illustrate the advantage of an internal resistive source modeling. The numerical results show that the internal resistive source modeling is numerically efficient and accurate in analyzing CPW and CPS circuits. ©1999 John Wiley & Sons, Inc.
