摘要：
For the research of 5G NR band mobile phone bezel antenna, this paper proposes an 8-Element Multiple-Input Multiple-Output (MIMO) handset bezel antenna design for 5G New Radio (5G NR) bands. Moreover, the MIMO antenna’s array is implemented by loading 8 identical antennas (Ant1–Ant8) into the metal bezel of the smartphone to form an 8-antenna array for a sub-6 GHz 8 × 8 MIMO system. In this setting, each antenna unit is a slot antenna type consisting of a Chinese character “ ”-shaped slot, as well as a 50 Ω micro-strip feeder; note that a satisfactory impedance matching is achievable in the upper-frequency band by loading a tuning stub on the feeder. The proposed 8-element antenna array covers 5G new radio (NR) band including N77 (3.3–4.2 GHz), N78 (3.3–3.8 GHz), N79 (4.4–5.0 GHz), and a Wi-Fi (2.4 GHz) band with a 10 dB impedance bandwidth. It is important to note that in addition to exhibiting ideal antenna efficiency and envelope correlation, the isolation between adjacent array elements is > 10 dB, and the peak gain is 3 dBi. In summary, the influence of the user’s hand on the antenna is analyzed to ensure the robustness of the MIMO antenna system in practical applications. © 2023, Electromagnetics Academy.
