Abstract
The Z-shaped four-port Plasmonic MIMO antenna for THz communication is proposed in the manuscript. The slotted design gives giving ultra-wideband response using the concept of defected ground structure. The analysis is carried out for a spectrum of 5 THz to 50 THz. The overall dimensions of the structure are 110 × 110 µm2 which makes the design compact. The design parameters are optimized to increase the gain and bandwidth of the proposed design. The proposed antenna design provides a bandwidth of 44.5 THz, a gain of 18.9 dB and an isolation of 56 dB after optimization. Different MIMO antenna parameters like ECC, TARC, DG and MEG are also investigated in this research. The proposed design opens a new way to target applications like THz 6G communication, and THz wireless personal area networks (TWPAN). The comparative analysis is also presented to show the advancement of the design.
