Beam-Steering Transmitarray Based on 180° Reconfigurable Element

a novel C-band antenna element with 180° reconfigurable phase is proposed for beam-steering transmitarray (BST). The phase reconfigurability of the element is realized by controlling the varactor diodes embedded and the phase coverage is confirmed by full wave simulations between 4.85 and 5.35 GHz. A transmitarray consisting of 16×16 elements is designed and simulated and the results demonstrate the beam-steering capability of the array.
