Year: 2026
Type: conference-paper
Abstract: This work presents a compact dual-element MIMO antenna designed for terahertz applications in emerging 6G wireless networks and high-resolution sensing systems. We developed L-shaped microstrip patch elements integrated with rectangular slot configurations on a polyimide substrate, achieving a footprint of just 75 × 170 µm2. Through comprehensive electromagnetic simulations, we validated dual-band operation at 1.89 THz and 2.62 THz. The design exhibits exceptional impedance matching, with return loss values reaching −34.02 dB and −29.32 dB at the respective bands. VSWR values of 1.05 and 1.08 confirm near-perfect matching, while the combined operational bandwidth spans 534 GHz. Peak directivity gains of 5.51 dBi and 5.28 dBi were achieved with linear polarization characteristics. Our MIMO analysis reveals outstanding diversity characteristics: envelope correlation coefficient as low as 9.8 × 10−14and 1.6 × 10−10, diversity gain reaching 9.999 dB and 10.0 dB, channel capacity loss of approximately 2.6 × 10−6and 2.9 × 10−6bps/Hz, and mean effective gain of −3.03 dB. These results demonstrate the antenna’s potential for high-speed wireless communications, biomedical tissue imaging, molecular spectroscopy in pharmaceutical applications, and security screening systems.
