© 2017 IEEE. In this paper, we propose a novel adaptive beamforming algorithm combining methods of electromagnetism and signal processing, which embeds antennas' active pattern (AP) in the diagonal loading (DL) method. It can significantly reduce the beamformer's performance degradation brought by the inconsistency between hypothesized idealized antenna models and practical ones. Embedding AP adds the array's electromagnetic characteristics to the algorithm, therefore improves the performance of the robust beamformer. Simulation and measurement results indicate that the proposed method has an appealing performance when there are mismatches of antennas' physical aperture.
