Abstract: ABSTRACT In this work, we propose a novel solution for a switched beamformer called the adjustable phased array system (APAS). By programming electronic switches, the implemented four‐antenna APAS circuit generates 12 phase‐shift angles that are multiples of . Compared to the legacy Butler matrix, the proposed APAS only needs one input port and four output ports and can provide more beam patterns with lower cost. Therefore, the APAS structure is a practical solution to satisfy the modern multiuser MIMO applications. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:1375–1378, 2014
