Abstract
A simple optically transparent multi-port dual polarized wideband THz-MIMO antenna is presented in this study. The main focus of the work is to design an optically transparent antenna using indium tin oxide (ITO) as conducting material on polyimide substrate. Further, multi elements are integrated in the configuration without compromise of the MIMO performance of the antenna. The antenna development process begins with design of single element. A circular monopole radiator with an etched curved-shaped slot is developed first. The bottom of the antenna is integrated with partial ground plane with inverted L-shaped strip. This configuration of the single element antenna is provided wideband in THz frequency range. Further, two-port (parallel and orthogonally placed element scenarios) MIMO antenna is implemented to investigate the MIMO performance stability. The orthogonal arrangement of antenna element is accounted as a best arrangement to extend antenna into four-port configuration. Proposed four-port antenna performance is evaluated in terms conventional parameters (gain, efficiency and radiation patterns) and MIMO parameters (ECC, TARC, Diversity gain, and CCL). and four-port MIMO configurations. The antenna has offered wide bandwidth (0.55–10.6 THz). The gain of the antenna is 7.1 dBi over the interested frequency range. The circular polarization characteristics is exhibited by axial ratio which is shown 3-dB ARBW for 1–2.1 THz. The evaluated MIMO performance results port isolation, ECC, TARC, DG, and CCL are − 20 dB, 0.01457, − 25 dB, 10, 0.07322 respectively. Comparatively, the proposed MIMO antenna systems performance results and wide operating bandwidth in THz range is appropriate for optically transparent systems and sensing, Industry 4.0, IoT and 6G applications.
