Abstract

The paper proposes a high gain, low ECC, and high isolation THz MIMO antenna array for future generation wireless applications to accommodate a growing population of mobile users. A THz MIMO antenna array is designed with dimensions of 1200 × 2200 × 191.29 µm3. It employs the array of double-slit complementary split-ring resonators (D-CSRRs) on the bottom layer to improve the gain, return loss, and isolation. The gain of the proposed antenna array is 11.3 dBi with 66.45 % radiating efficiency at 0.65 THz. The −10 dB impedance bandwidth lies from 0.62–0.66 THz. The parameters of the MIMO antenna are evaluated such as isolation, envelope correlation coefficient (ECC), diversity gain (DG), and channel capacity loss. The ECC and DG value observed are 2.84 × 10−6 and 9.98 dB, respectively, at 0.65 THz. The channel capacity loss and isolation of the proposed MIMO antenna array are below 0.4 bps/Hz and (|S 21| > 25 dB), respectively, in the complete operating band. The suggested THz MIMO antenna array can be utilised for THz high-speed wireless communication, video-rate imaging systems, sensing, the medical field for cancer imaging, security scanning, and the detection of illicit goods.

面向未来新一代无线应用的太赫兹 MIMO 天线阵列

本文提出了一种高增益、低 ECC 和高隔离度的 THz MIMO 天线阵列，用于未来一代无线应用，以适应日益增长的移动用户。设计的太赫兹 MIMO 天线阵列尺寸为 1200 × 2200 × 191.29 µm3。它在底层采用了双缝互补分环谐振器（D-CSRR）阵列，以提高增益、回波损耗和隔离度。拟议天线阵列的增益为 11.3 dBi，在 0.65 太赫兹时的辐射效率为 66.45%。-10dB阻抗带宽为 0.62-0.66 THz。对多输入多输出天线的参数进行了评估，如隔离度、包络相关系数（ECC）、分集增益（DG）和信道容量损失。在 0.65 THz 时，观察到的 ECC 和 DG 值分别为 2.84 × 10-6 和 9.98 dB。在整个工作频段内，建议的 MIMO 天线阵列的信道容量损耗和隔离度分别低于 0.4 bps/Hz 和 (|S 21| > 25 dB)。所建议的太赫兹多输入多输出天线阵列可用于太赫兹高速无线通信、视频速率成像系统、传感、医疗领域的癌症成像、安全扫描和非法物品检测。

期刊介绍： Frequenz is one of the leading scientific and technological journals covering all aspects of RF-, Microwave-, and THz-Engineering. It is a peer-reviewed, bi-monthly published journal. Frequenz was first published in 1947 with a circulation of 7000 copies, focusing on telecommunications. Today, the major objective of Frequenz is to highlight current research activities and development efforts in RF-, Microwave-, and THz-Engineering throughout a wide frequency spectrum ranging from radio via microwave up to THz frequencies. RF-, Microwave-, and THz-Engineering is a very active area of Research & Development as well as of Applications in a wide variety of fields. It has been the key to enabling technologies responsible for phenomenal growth of satellite broadcasting, wireless communications, satellite and terrestrial mobile communications and navigation, high-speed THz communication systems. It will open up new technologies in communications, radar, remote sensing and imaging, in identification and localization as well as in sensors, e.g. for wireless industrial process and environmental monitoring as well as for biomedical sensing.
