“…The inference of the table is that Singh et al 31 designed the antenna which was operated at 1.43 THz, and the 14 Singh and Singh 31 Mittala and Sidhu 32 Ullah et al 33 Vahdati return loss of −34 dB was obtained. Hocini et al 14 and Sidhu et al 32 investigated the THz antenna structure and it produced the gain of 8.9 and 7.9 dB at the resonant frequency of 0.63 THz. Shahid et al 33 proposed a THz antenna and obtained the output of −34 dB return loss with gain of 6.8 dB.…”

SummaryNowadays, the wireless communication is improved in numerous ranges, and the use of the high speed of data rate in the communication systems is needed. The standing problem of high‐performance planar antenna is reduced by the recently developed artificial dielectric called photonic crystal, which is used to control and manipulate the optical property of light. This paper addresses the slotted tube antenna structure, and the investigation is done by the concept of triangular lattice structure based on the photonic crystal. This utility enhances the return loss of −57.81 dB and the voltage standing wave ratio (VSWR) of 1.002 at 2.37 THz operating frequencies. The increase in hole radius provides the shifting in zero dispersion point towards the shorter wavelength that helps for faster data rate transmission applications. Further, to characterize the model of the proposed antenna, the optimal value of the air hole, lattice constant value between holes and the thickness of the slot are found and the related parameters of such antenna are studied with the support of simulation software CST microwave studio.

“…In this proposed antenna topology, the width of the rings and the distance between them are used to achieve impedance matching and optimal efficiency. In [4] demonstrates a polyimide based optical rectangular patch antenna capable of operating at THz frequencies. The effects of variation in the substrate width on the return loss and percentage bandwidth has also been observed.…”

Terahertz (THz) technology can be widely used in radar, remote sensing, homeland security and counter-terrorism, high-secret data communication and transmission, atmospheric and environmental monitoring, real-time biological information extraction, and medical diagnosis. It is the frontier of current research. However, most of highly sensitive THz detectors work in a relatively narrow frequency range. It attracts great attention to design a high-gain terahertz antenna operates in a wide spectrum range. In this paper we propose a new structure of fractal butterfly antenna with high gain which can be used for broadband THz detection. This fractal butterfly antenna is constructed by independent fractal unit groups on butterfly antenna, which simplifies the antenna manufacturing process and reduces the manufacturing cost. The antenna can operate in the 0.1-10 THz frequency band, with impedance bandwidth of 85% resonated at 4.9 THz, return loss of as small as -33.59 dB, and maximum gain of 16.95 dB. Among the antenna with 3 to 4 fractal unit groups, the best operation band of the antenna is 6.2-6.4 THz. The proposed fractal butterfly antenna can effectively improve the performance of terahertz detectors, and provide the possibility for detection research in higher frequency bands.

A tree-shaped graphene based microstrip MIMO antenna for terahertz applications is proposed. The proposed MIMO antenna is designed on a 600×300 µm2 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.
