The spatial phase variations in feeding a microwave cavity with asymmetrical amplitudes and phases were calculated using the finite element method (FEM) that was applied to the three-dimensional (3D) model of the microwave cavity developed at the National Metrology Institute of Japan (NMIJ)/AIST. The distributed cavity phase shift (DCPS) in an atomic fountain frequency standard was calculated for atomic interaction with the position-dependent amplitudes and phases inside the cavity. The tolerances of asymmetry in the phases and amplitudes of microwaves were determined in order to achieve an uncertainty of $5\times 10^{-16}$ with respect to the DCPS.
