Abstract

The article presents design and steps involved in designing a wideband multiband optimized MIMO antenna for terahertz (THz) applications. The 2x2 MIMO antenna is designed by incorporating combinations of circular and rectangular shaped slots, and the ground plane is modified with an extended circular shaped defect. The bandwidth of the proposed antenna is improved by altering full ground to partial ground. The dual band 2x2 MIMO antenna provides (26.66% 1.3-1.7THz) and (51.66% 3.9-7THz) impedance bandwidth achieving <−25 dB isolation between the antenna elements and having a peak gain of 8.8dB. In addition, it has an omnidirectional radiation character with high-directivity that allow the transmitter signal to be propagated over a practical communication channel. Moreover, the feature is evaluated by computing MIMO metric parameters such as Diversity Gain (DG), Envelope Correlation Coefficient (ECC), Mean Effective Gain (MEG), Total Active Reflection Coefficient (TARC) and Channel Capacity Loss (CCL). The proposed 2x2 MIMO antenna could be an excellent candidate for high-speed indoor wireless communication systems as well as for explosive detections, homeland defense system, medical imaging, pharmaceutical analysis and material characterization application.
