Based on this antenna, the layout of the antenna of the aircraft is designed, and the determination of occlusion is considered. The multi-layer fast multipole and finite element method are used in the model simulation to solve the problem. The integral method of mixing field is used to improve the convergence. The calculation of the complicated electromagnetic field in large size model is solved. The calculation speed and accuracy are taken into account. Antenna, 4 antenna, 5 antenna layout in different ways far field pattern simulation results, and propose a method for the evaluation of the direction of the aircraft antenna layout of a certain reference value.
