In this paper, the finite difference time domain model for the antenna in package is presented. The distribution of the electric field in the package cavity is analyzed, and a method that reduces the near field is proposed. By arranging via position reasonably, at most the area of the cavity electric field is uniform and decreased less than 10 dBV/m. The measured and simulated results show that the new shielding structure can decrease the electric field in the package cavity by about 10 dBV/m.
