Terahertz (0.1-10 THz) wireless communication will be the future technology to reach a top-notch data rate. THz is one of the most promising candidates for 6G systems because it provides enormous bandwidth, up to 100 GHz, and a massive data rate of up to 1 Tbps. THz antennas, antenna arrays, and MIMO antenna arrays in 6G are hot research topics for implementing 6G wireless communication systems. The 6G aims to continue to enhance the features of the 5G as it is capable of achieving the maximum high-speed data rate, excellent reliable communication, massive connectivity, and very low latency connectivity. The 6G requirements need high-gain antenna arrays and MIMO antenna arrays to combat the effect of atmospheric losses in high frequencies. An in-depth discussion of the planar THz antennas that have been extensively used in THz applications like imaging, sensing, and Internet-of-Things (IoT) has been conducted. The study of the THz antennas, antenna arrays, and MIMO antennas on different conducting materials such as copper and graphene, which are designed on different dielectric substrates such as polyimide, quartz, liquid crystalline polymer, and polytetrafluoroethylene, has been carried out in detail. Metamaterial, photoconductive, plasmonic antennas, and THz beamforming are significant parts of THz communications. This paper also provides antennas and antenna arrays based on them.

“…In 2018, Kushwaha [ 7 ] proposed a design for a high-gain THz microstrip patch antenna based on photonic crystals, using a polyimide substrate, and the gain was 7.934 dB and the resonant frequency was 0.6308 THz. In 2019, to further improve the gain, Nurfitri [ 8 ] proposed a design for a 1 × 3-series-fed antenna array on a Rogers RT duroid 5880 dielectric substrate, achieving a gain of 11.2 dBi at 0.312 THz. In 2020, in order to achieve the miniaturization and reconfiguration of the THz antenna, Abohmra [ 9 ] designed an antenna with a polyethylene nathoate substrate, operating in the frequency band of 0.9–1.2 THz.…”

A terahertz band (0.1–10 THz) has the characteristics of rich spectrum resources, high transmission speed, strong penetration, and clear directionality. However, the terahertz signal will suffer serious attenuation and absorption during transmission. Therefore, a terahertz antenna with high gain, high efficiency, and wide bandwidth is an indispensable key component of terahertz wireless systems and has become a research hotspot in the field of antennas. In this paper, a high-gain broadband antenna is presented for terahertz applications. The antenna is a three-layer structure, fed by a grounded coplanar waveguide (GCPW), using polytetrafluoroethylene (PTFE) material as the dielectric substrate, and the metal through-hole of the dielectric substrate forms a substrate-integrated waveguide (SIW) structure. The metal fence structure is introduced to reduce the coupling effect between the radiation patches and increase the radiation bandwidth and gain. The center frequency is 0.6366 THz, the operating bandwidth is 0.61–0.68 THz, the minimum value of the voltage standing wave ratio (VSWR) is 1.00158, and the peak gain is 13.14 dBi. In addition, the performance of the designed antenna with a different isolation structure, the length of the connection line, the height of the substrate, the radius of the through-hole, and the thickness of the patch is also studied.

“…An antenna is one of the main components of a wireless electromagnetic system, such as THz biomedical imaging systems. Several investigators have proposed using antennas for breast cancer imaging using FR-4 and Rogers RT5880 as the dielectric substrate [17]- [19]. The main issue associated with using these materials as substrates is that their efficacy for application in the THz region has not been substantiated.…”

In this investigation, the inset fed and array techniques were used to focus the beamwidth in the desired direction.…”

Cancer is the second deadliest disease globally, with approximately 18 million cases and 9.6 million deaths in 2018. There were 2.088 million breast cancer cases and 627 thousand deaths. This cancer is the second most prevalent after lung cancer, resulting in the fifth most cancer deaths worldwide. A critically important technique for the detection of primary-stage tumors or cancer is imaging. Early detection of cancer is necessary to minimize the number of fatalities associated with breast cancer. Several techniques have been applied to breast tissue imaging such as computed tomography scans (CT Scans), transrectal ultrasound (TRUS), magnetic resonance imaging (MRI), positron emission tomography (PET), and single-photon emission computed tomography (SPECT), but these techniques have well-known limitations. THz imaging is also one of the techniques for early detection. THz imaging approaches address key deficiencies in alternative techniques and are typically non-ionizing, non-contact, non-destructive, and have a high spatial resolution. An appropriate detector is a crucial aspect of the development of this promising technique. In this report, a THz siliconbased antenna with a frequency centered at 0.312 THz is proposed for application to breast cancer imaging. A silicon substrate has a high permittivity and is useful for device miniaturization. Inset-fed and array techniques are essential for focusing the beamwidth in the desired direction. The results show that the proposed design can be used to develop a directional antenna with reliable performance. This study will contribute to the development of a THz imaging system for early breast cancer detection.
