Summary:This paper introduces a linearly polarized beam-deflection array that operates in the X-band and has a phase resolution of 1 bit. The transmission unit consists of three media layers and three metal layers. Its metal layers include metal strips with specific arrangements are used to twist the polarization of electromagnetic waves by \boldsymbol{\pm 90^{\circ}} , and then the middle metal layer is rotated by 90° to form a phase difference of 0°/180°. A \boldsymbol{20\times 20} transmission array with beam deflection is designed using this unit. The designed antenna array shows good electrical characteristics including gain of 16 dBi at 11GHz and stable radiation patterns at both H- and V-planes.
