摘要：

In this paper, the design and the experimental validation of a polarization reconfigurable microstrip phased array is presented. The reconfigurability between the right-handed (RHCP) and left-handed (LHCP) circular polarization is achieved using electronic switches (PIN diodes) combined with truncated corners microstrip radiators. In the design, special attention was given to the matter of reducing back lobe radiation effects using the concept of asymmetric positioning of the radiators with respect to the ground plane. Afterward, the main lobe axial ratio behavior for several beam steering and side lobe level conditions are investigated. Finally, the polarization reconfigurability is achieved and the design is validated through the good agreement between theoretical and experimental results. (C) 2018 Elsevier GmbH.
