A Micro Scaled Dual Element MIMO Antenna with Improved Isolation for Terahertz Applications

A dual-element MIMO antenna with enhanced bandwidth of 0.038THz (0.457-0.495THz) by using DGS is presented for THz applications. By utilising a rectangular slot in the ground plane, the suggested MIMO antenna's maximum return loss and isolation are, respectively, -28dB and -31.8dB at the resonant frequency (0.475THz). The diversity performance of MIMO is also studied with ECC < 0.001, DG ≤ 9.98dB and mean effective gain (MEG)-ratio within ±3 dB. The 720×520× 60μm
³
dimension Rogers RO4003 substrate, which has a εr of 3.55 and a loss tangent of 0.0027, serves as the foundation for the proposed MIMO antenna. The planned MIMO radio wire is reasonable for fast brief distance correspondence, video rate imaging, and detecting in the THz band.
