Abstract

The investigation of new technologies operating in the terahertz (THz) frequency range has been spurred by the growth of data-intensive applications and the need for extremely rapid wireless communication. This work proposes a terahertz (THz) multiple input multiple output (MIMO) antenna designed on a polyamide substrate of dimension 20 × 46 × 2 μm3, operating in the frequency range of 3.3-10.4 THz. The field interaction between the elements is neutralized using a hybrid decoupling structure comprised of a neutralization line and a defected ground plane, providing isolation better than 22 dB. The MIMO diversity features are examined and found to be ECC<0.03, DG close to 10 dB, TARC<-10 dB, and CCL<0.25 bps/Hz.
