Abstract(in English) In order to investigate the calculation accuracy of the FDTD method when applied to a patch antenna analysis, we compared the simulated resonant frequency with measured one. We used various numerical models and relative errors were calculated. In the case of using uniform cells, the error decreased as the size of the cells decreased. But the computational cost extremely increased for decreasing the error less than l.0%. In the case of using nonuniform cells, which kebt the error about l.5% by setting small cells near the edges of the antenna, the calculation efficiency increased.
