“…It is seen that excellent radiation beams over of 0-70 scanning angles are provided. As shown, the design provides well-defined radiation beams at 0°,15°, 30°,45°, 60°, and 70° which could cover half-space of the radiation coverage for the smartphone mainboard [35][36][37]. Fundamental properties of the design including directivity and efficiencies for the steered beams of the mobile-phone array at 19 GHz design are presented in Fig.…”

In this paper, a high efficiency phased array antenna is introduced for fifthgeneration (5G) smartphones. The configuration of the design is achieved by employing eight insensitive L-ring/slot-loop resonatorss with linear array form on the top of the handset 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 a frequency bandwidth of 18-20 GHz with a single resonance at 19 GHz. The designed antenna exhibits wide beam-steering, high efficiencies, and sufficient gain levels at 19 GHz of 5G communications. In addition, the proposed phased array design has sufficient radiation behavior in the adjacency of user-hand phantom. Moreover, its characteristics are insensitive for various substrate types.

“…Every element of the antenna are located sideways the two wide sides of a 130×75 mm 2 ground plane, which is almost the identical measurement of today's smart mobile phones. Eight antenna components are designed on two minor substrates which are placed perpendicular on the central system substrate [25][26][27][28].…”

In this new article, a different model of dual-band MIMO compact antenna array is proposed for the upcoming fifth generation smartphone mobile terminal. The antenna conatins eight antenna elements covering dual frequency rang including 3.18-3.96 GHz and 4.95-5.52 GHz of sub 6 GHz 5G spectrums. The elements are fed by modified Fshaped microstrip feeding lines. Essential characteristics of the suggested model are examined. It proposes adequate S-parameters, suitable isolation, sufficient radiation analysis, and efficiency. At 3.6 GHz the Ant 5 has maximum return loss of-25dB while Ant 7 has maximum return loss of-26dB at 5.2 GHz of the proposed dual band frequency of 5G smartphones.

“…The antenna elements are arranged with a distance of d = 5 mm. As it can be observed, it is composed of eight 26 GHz Quasi-Yagi antenna elements and could be used on the top/bottom portions of the smartphone PCB to form two sets of linear phased arrays [24,25]. Figure 9 shows a phased array system architecture with a feeding network that could be used for the linear phased array Quasi-Yagi antenna and can be demonstrated using phase shifters for beam switching.…”

The focus of this manuscript was to propose a new phased array antenna design for the fifth generation (5G) mobile platforms. Eight elements of compact Quasi-Yagi antennas were placed on the top portion of smartphone printed circuits board (PCB) to form a beam-steerable phased array design. The −10 dB impedance-bandwidth of proposed 5G smartphone antenna spans from 25 GHz to 27 GHz providing 2 GHz bandwidth with less than −16 dB mutual coupling function. A coax-to-microstripline with a truncated crown of vias around the coaxial cable was used as a feeding mechanism for each radiation element. An Arlon Ad 350 substance with properties of ε = 3.5, δ = 0.003, and h = 0.8 mm was chosen as the antenna substrate. The proposed phased array antenna provides wide-angle scanning of 0°~75° with more than 10 dB realized gain levels. For the scanning angle of 0°~60°, the antenna array provides more than 90% (−0.5 dB) radiation and total efficiencies. In addition, the specific absorption rate (SAR) function and radiation performance of the design in the presence of the user-hand/user-hand have been studied. The results validate the feasibility of the proposed design for use in the 5G handheld devices. Furthermore, using the presented Quasi-Yagi elements, the radiation properties of 2 × 2, 4 × 4, and 8 × 8 planar arrays were studied and more than 8.3, 13.5, and 19.3 dBi directivities have been achieved for the designed planar arrays. The results show that the designed arrays (linear & planar) satisfy the general requirements for use in 5G platforms.
