Design of graphene-based multi-input multi-output antenna for 6G/IoT applications

In the future, 6G wireless communications will be integrated into various applications. It is expected that it handle all Internet of Things services as well satellite communications. Additionally, predicted to support machine learning (ML) and artificial intelligence (AI). So this work investigated four orthogonal ports graphene-based multiple-input multiple-output (MIMO) antenna in terahertz frequency regime. With wide-band (7.1-13) THz, minimum return loss close -30 dB a good isolation value. That was designed over silicon dioxide (Sio2) 100×100 substrate with thickness 10 µm maximum gain reaching 8.3 at 11 THz. By adjusting provided DC voltage, chemical potential graphene can tuned, which turn allows for MIMO characteristics changed. Envelop correlation coefficient (ECC) diversity (DG) were presented design. addition, these values determined assess compatibility difficulties connected communication short distance. The geometry adaptable applications THz band highperformance requirements, such sensing, scanning security threats, biomedical applications, systems high speed built on standard, internet things (IoT).
