In this work, a millimeter-wave wide-angle scanning phased array is proposed. The antenna consists of two rectangular metasurface cells and it is fed by a L probe, which can obtain a large impedance bandwidth and a wide beam in E-plane. Then, the 1×2 subarray is designed to construct a 8×2 wide-angle scanning phased array with the array spacing of 0.38 λ0. A grounded “II” structure is loaded between the antenna elements to improve the active S-parameters when the phased array is scanning. As results, the 10-dB impedance bandwidth of the proposed array can cover a wide band of 66-78GHz (16.7%). Moreover, it can scans up to ±65° in the whole operating band-width, while gain drop is less than 3 dB, and the maximum scan range reaches ±69°.
