Abstract

In this paper, a high efficiency phased array antenna is introduced for fifth-generation (5G) smartphones. The configuration of the design is achieved by employing eight substrate-insensitive L-ring/slot-loop radiators in a uniform linear array on the upper edge of the smartphone mainboard. The design exhibits high radiation performances even though the beam-steerable array is implemented on a lossy FR-4 material. The proposed design exhibit an impedance bandwidth of 18-20 GHz with the center frequency of 19 GHz. It offers satisfactory performance including beam-steering, high efficiency indicating its promising potential for beam-steerable 5G smartphones. In addition, its characteristics are insensitive for different types of substrates. Furthermore, the designed antenna array offers sufficient radiation performances in the presence of the user-hand.
