“…In the literature, researchers have designed and reported some compact THz antennas but they are capable to operate with very narrow bandwidths of 5.85% [21], 8.2% [22], 3.78% [23], and 6.67% [24], which restricts their suitability for a wideband short distance high speed wireless THz communications. So, the researchers have proposed different design methods to improve the bandwidth of the microstrip antenna in the THz regime by implementing photonic crystal structures [25][26], photonic crystal based frequency selective surface [27], electromagnetic crystal substrate [28], unslotted simple rectangular patch [29][30], adding superstrate [31] and incorporating slots on patch [32]. Also, a multi-layer array antenna is investigated and proposed in ref.…”

“…This motivated the authors of this paper to design and analyze a compact microstrip MIMO antenna with wide impedance bandwidth and better diversity performance for high speed short range wireless communication systems in the THz band. In this paper, the authors have designed a two-element spatial diversity multiple-input multiple-output (MIMO)THz antenna which occupies less area and offers much better impedance bandwidth compared to the reported single element antennas [25][26][27][28][29][30][31][32], array antenna [33] and MIMO antennas [34][35]. The reason behind the selection of spatial diversity MIMO antenna is to exploit its multipath characteristics to provide high data rate, better channel capacity, interference mitigation, extended coverage, and improved signal reliability by avoiding fading.…”

A tree-shaped graphene based microstrip MIMO antenna for terahertz applications is proposed.The proposed MIMO antenna is designed on a 600×300 μm 2 polyimide substrate. The designed MIMO antenna exhibits a wide impedance bandwidth of 88.14% (0.276 -0.711 THz) due to the suggested modifications in the antenna configuration. The MIMO design parameters like total active reflection coefficient (TARC), mean effective gain (MEG), envelope correlation coefficient (ECC) and diversity gain (DG), Channel capacity loss (CCL) are evaluated and their values are found within acceptable limits. The proposed MIMO structure offers MEG ≤ −3.0 dB, TARC≤ -10.0 dB, DG≈ 10 dB, CCL < 0.5 bps/Hz/sec and ECC < 0.01 at the resonant frequency. At the resonant frequency, the isolation between the radiating elements of the proposed MIMO is recorded as −52 dB. The variations in operating frequency and S-parameters are also analyzed as a function of the chemical potential (μc) of the graphene material.The parametric analysis, structural design evolution steps, surface current distribution, antenna characteristics parameters and diversity parameters are discussed in detail in this paper. The designed MIMO antenna is suitable for high speed short distance communication, video rate imaging, biomedical imaging, sensing, and security scanning in the THz frequency band.

A quad element multiple-input-multiple-output (MIMO) antenna with improved impedance bandwidth of 0.126 THz (0.198-0.324 THz) by using defected ground structure (DGS) is proposed for terahertz applications. The four elements are placed orthogonally to one another to reduce mutual coupling and envelope correlation coefficient (ECC). The maximum isolation of the proposed MIMO antenna is 34 dB at 0.290 THz frequency. The diversity performance characteristics of the proposed antenna are studied in terms of ECC, diversity gain (DG), mean effective gain (MEG), total active reflection coefficient (TARC), and isolation between the ports, and the obtained values are 0.05, 9.9, AE 3, À5, À10, respectively. Each antenna has a peak gain of 4.4 dBi with an average radiation efficiency of 92.5%. The proposed MIMO antenna is designed on a Rogers RO4003 substrate having a dielectric constant of 3.55, and a loss tangent of 0.0027 with a dimension of 700 Â 700 Â 55 μ m 3 .Further analyses of path loss in free space, atmospheric absorption, and roughness factor in indoor surfaces for THz communication are also studied. The designed MIMO antenna is suitable for high-speed short distance communication, video-rate imaging, biomedical imaging, sensing, and security scanning in the THz frequency band.
