This paper introduces a low-profile 5G phased array with a broad operation band for smartphone applications. The design procedure is simple and easy to accomplish. It is composed of eight endfire dipoles with a 1×8 linear array arrangement at the top side of the smartphone. The design is arranged on an RT5880 material with 0.25 mm thickness. The resonators of the array are placed on the same copper side of the ground plane. The employed elements have low profiles with discrete-feeding ports. The proposed array offers a broad impedance bandwidth from 28 to 38 GHz which could cover 5G candidate frequencies. Moreover, the coupling of the single radiators is less than-20 dB at the centre frequency. Well-defined end-fire radiation, good efficiency, highly miniaturized profile, wide beam-steering, sufficient gain levels, and wide operation band are the promising characteristics of the introduced array.
