These four antenna arrays are briefly investigated to evaluate their beam width performance, ability to detect a false signal, and SINR power pattern performances. Robust techniques�fixed diagonal loading (FDL), optimal diagonal loading (ODL), variable diagonal loading (VDL), and new variable loading (NVL) techniques�are applied, and the NVL technique is found to be superior and provides the best performance with the proposed LCCAA beamformer. With an SINR of 40.45 dB, 40.29 dB, 40.18 dB, and 39.99 dB for 0°, 1°, 2°, and 3° disparity angles, respectively, and output powers of �0.019 dB, �0.076 dB, and �0.171 dB for 1°, 2°, and 3° disparity angles, respectively, LCCAA beamformers using the NVL technique outperform other beamformers with different robust approaches. © 2022 by the authors. publisher: MDPI date: 2022 type: Article type: PeerReviewed identifier: Rahaman, I. and Jafor, M.S. and Singh, N.S.S. and Haque, M.A. and Biswas, A.K. and Rahman, M.A. and Zakariya, M.A.B. and Abro, G.E.M. and Sarker, N.
