This article is aimed at designing an inventive compact-size quad-port antenna that can be operated within terahertz (THz) frequency spectra for a 6G high-speed wireless communication link. The single-element antenna comprises a lotus-petal-like radiating patch and a defected ground structure (DGS) on a 20 × 20 × 2 µm3 polyamide substrate and is designed to operate within the 8.96–13.5 THz frequency range. The THz antenna is deployed for a two-port MIMO configuration having a size of 46 × 20 × 2 µm3 with interelement separation of less than a quarter-wavelength of 0.18λ (λ at 9 THz). The two-port configuration operates in the 9–13.25 THz frequency range, with better than −25 dB isolation. Further, the two-port THz antenna is mirrored vertically with a separation of 0.5λ to form the four-port MIMO configuration. The proposed four-port THz antenna has dimensions of 46 × 46 × 2 µm3 and operates in the frequency range of 9–13 THz. Isolation improvement better than −25 dB is realized by incorporating parasitic elements onto the ground plane. Performance analysis of the proposed antenna in terms of MIMO diversity parameters, viz., envelope correlation coefficient (ECC) < 0.05, diversity gain (DG) ≈ 10, mean effective gain (MEG) < −3 dB, total active reflection coefficient (TARC) < −10 dB, channel capacity loss (CCL) < 0.3 bps/Hz, and multiplexing efficiency (ME) < 0 dB, is performed to justify the appropriateness of the proposed antenna for MIMO applications. The antenna has virtuous radiation properties with good gain, which is crucial for any wireless communication system, especially for the THz communication network.

“…A graphene-based 2-port MIMO antenna offers THz bandwidth from 1.76 THz to 1.86 THz with isolation < 25.0 dB [25]. A four-port antenna with a dimension of 45µm×45µm generates a bandwidth range of 2.38 -11.18 THz and utilizes a self-similar elliptic structure with a polyamide substrate [26]. A tunable-enhanced isolation MIMO antenna is reported [27], which provides a bandwidth range of 5.68 -6.51THz and achieves ECC = 4.818×10 -7 .…”

This communication reports a conformal offset feed Quasi-Yagi antenna at 300 GHz for high-directional applications. A novel offset feed mechanism is adopted to obtain directional behavior from a conventional planar structure. The proposed antenna is designed on a Silicon-dioxide (SiO 2 ) dielectric substrate having a permittivity (ε r ) of 4 and a height of 60μm. A gold material of thickness 5µm is used as a conducting metal in the top and bottom layers. This antenna consists of an offset feed patch, partial ground as a reflector, and three director elements forming a Quasi-Yagi antenna. This conformal structure operates from 270 GHz to 333 GHz and provides a peak gain of 8.62dBi at 300 GHz in the end-fire direction. An analysis of different metals and parametric variation in metal thickness, substrate thickness, patch length, and width is also reported for a better understanding of the evolution of the proposed structure. A lumped equivalent circuit is also developed for the proposed structure to study its transmission line model. A good agreement is also noted between the EM simulation (HFSS, CST) and circuit simulation (ADS).

“…The MIMO antenna design has been investigated for use in 5G communication, and has also been presented for integration with portable devices [ 22 ]. The use of the broadband THz four-port MIMO antenna covering a broad spectrum of frequencies was presented in [ 23 ]. The isolation of the MIMO antenna is important, as all the radiating elements need to be isolated from each other.…”

The need for high-speed communication has created a way to design THz antennas that operate at high frequencies, speeds, and data rates. In this manuscript, a THz MIMO antenna is designed using a metamaterial. The two-port antenna design proposed uses a complementary split-ring resonator patch. The design results are also compared with a simple patch antenna to show the improvement. The design shows a better isolation of 50 dB. A broadband width of 8.3 THz is achieved using this complementary split-ring resonator design. The percentage bandwidth is 90%, showing an ultrabroadband response. The highest gain of 10.34 dB is achieved with this design. Structural parametric optimization is applied to the complementary split-ring resonator MIMO antenna design. The designed antenna is also optimized by applying parametric optimization to different geometrical parameters. The optimized design has a 20 µm ground plane, 14 µm outer ring width, 6 µm inner ring width, and 1.6 µm substrate thickness. The proposed antenna with its broadband width, high gain, and high isolation could be applied in high-speed communication devices.
