Abstract: The dipole antenna array with trough reflector is widely applied to base stations for mobile communications. In order to simulate the antenna units and the trough reflector accurately and take the limitation of computation resources into account, this paper employs a kind of non-uniform FDTD algorithm in analyzing the radiation pattern. The numerical results show the effectiveness of this algorithm for antenna problems. -
