An efficient dipole array model for the accurate prediction of antennas radiation pattern

In this paper, we propose a simple and efficient method to predict the far field radiation pattern of unknown antennas. In the proposed method, equivalent dipole array model is reconstructed base on the electromagnetic field measured from the near field plane of the antennas under test. And then, the far field radiation from the unknown antennas is predicted through the radiation from the equivalent dipole array. The proposed method is validated by comparing the far fields obtained from the proposed method with that from the full wave method. Good agreements are obtained, which confirms the accuracy and efficiency of the proposed method.
