Abstract

This paper presents optimization of meander line antennas (MLA) for passive IC tags which contain non-linear circuits. In the present analysis, the tag antenna loaded by the Cockcroft-Walton circuit is analyzed by solving coupling equations for electromagnetic waves and non-linear circuit with FDTD method. The antenna shape is optimized so that the output voltage of the Cockcroft-Walton circuit is maximized using the micro genetic algorithm (μ GA). The computational burden in the optimization processes is effectively suppressed by truncating the transient computations. A criterion is introduced to evaluate the errors caused by the truncation. The present method yields the optimal MLA which has the greater output voltage in comparison with the dipole antenna.
