BOR-FDTD Analysis of Spherical Lens Multi-beam Antenna
The multi-beam antenna system has important applications in the aeronautics and astronautics field, which has caught much attention in recent years. This paper analyze a multibeam antenna consisted of spherical lens and multi feeds. Firstly, the single feeds performance of the spherical-lens antenna is analyzed. In view of the axial symmetry of the antenna, the BOR-FDTD method is used to reduce the three-dimensional solution to a two-dimensional one, and the number of the variable required by the solution will decrease greatly. As a result, it reduces the requirement of computer memory and makes it possible to calculate the electrically large object. The results calculated for the electrically small antenna agree well with that of the HFSS simulation, which proves the method is effective. Finally, the computation results for the electrically large antenna are presented.
