Massive Mimo Antenna Array at Terahertz Band for Short-Range Communications
摘要
In this paper, the hexagonal-shaped single-patch antenna and its 10 × 10 massive Multiple-Input Multiple-Output (MIMO) antenna array are proposed for wireless network applications. A polyimide, with a dielectric constant of 3.5 and thickness of 0.007 mm, is used as a substrate material. The rectangular microstrip patch antenna used to create the massive MIMO antenna array which is incredibly small in size having 0.0792 mm × 0.15 mm × 0.007 mm dimensions. Several performance metrics are computed for resonating frequency, including reflection coefficient, antenna gain, bandwidth, VSWR, antenna efficiency, ECC, and gain diversity. The proposed massive MIMO antenna array has a return loss of less than − 10 dB and covers an extensive bandwidth of 67.5 GHz. Over this bandwidth, the proposed array has a maximum attainable antenna gain of 20.8 dB with 86% efficiency.
