    Dual-band Endfire Phased Array Antenna for mmWave 5G NR Bands Applications
    (Institute of Electrical and Electronics Engineers, 2024) Zidour, Ali; Ayad, Mouloud; Alibakhshikenari, Mohammad; Guenad, Boumediene; Soruri, Mohamad; Kouhalvandi, Lida
    A dual-band endfire antenna phased array suitable for 5G NR mmWave bands applications is presented in this paper. The antenna introduces a novel radiating aperture array analogy based on open-end substrate integrated waveguide (SIW) technology to achieve wide dual-band operation and vertical polarization radiation. The simulated -10 dB impedance bandwidth achieves 17.4 % (25.2-30 GHz) lower band and 12.4 % (36.4-41.2 GHz) higher band covering mmWave 5G NR bands; n257, n260, and n261 with isolation levels higher than 15 dB over the operating bands. The peak realized gain is 8.8 dBi and 11.8 dBi in the lower and higher bands, respectively. The mmWave array delivers a scanning angle of ±50° and ±33° for a realized endfire gain higher than 6.5 dBi and 8.5 dBi at 28 GHz and 39 GHz, respectively.

    Wideband Endfire Antenna Array for 5G mmWave Mobile Terminals
    (Institute of Electrical and Electronics Engineers Inc., 2024) Zidour, Ali; Ayad, Mouloud; Alibakhshikenari, Mohammad; See, Chan Hwang; Lai, Ying-Xin; Ma, Yue.; Guenad, Boumediene; Livreri, Patrizia; Khan, Salahuddin; Pau, Giovanni; Denidni, Tayeb A.
    In this paper, a compact endfire antenna array with low-profile, small clearance, and wideband operation is proposed for millimeter-wave (mmWave) fifth-generation (5G) mobile terminals. The wideband operation is achieved by exciting two identical bow-tie dipoles inserted on both sides of a multilayer substrate fed by an asymmetric open-end stripline to slotline transition. The antenna performance is significantly improved by introducing a set of vertical metallic vias. The proposed antenna element can achieve 29 % from 24.2 GHz to 32.4 GHz with a peak realized gain that varies from 3.5 dBi to 4.5 dBi. A linear 4-element antenna array is arranged and fabricated to verify the proposed antenna beamforming capabilities. The simulated and measured bandwidth achieves a wide range of 34.4 % (24-34 GHz) to support 26, 28, and 30 GHz 5G mmWave bands with an isolation level better than 20 dB and a peak realized gain over the interested bands ranging from 7.56 to 8.14 dBi. The simulated array scanning angle is ± 68° at 28 GHz within 3-dB gain deterioration. Furthermore, the simulated spherical coverage has met the requirements of 3GPP standards which make the proposed antenna array a promising candidate to be integrated within mmWave 5G mobile devices
