A fast FDTD method for the analysis of antennas loaded by nonlinear electric circuits is introduced. In the present analysis, the modified nodal analysis (MNA) method is coupled with the FDTD method. The time-periodic explicit error correction (TP-EEC) method is applied to the MNA method for accelerated computation of the transient processes. The present method is applied to analysis of simplified models of an RFID tag composed of a nonlinear electric circuit and line antenna. It is shown that the present method can effectively shorten the computational time by accelerating the transient processes.
