“…However, software equalizations were chosen for this research to reduce this verification's high price and reach beyond a couple of thousand Euros. Therefore, it is optimal to use dual different commercial electromagnetic (EM) software, which works at different methods, to obtain a decent simulation equalization that the simulation results will be similar to each other, which has also been used at [12], [13].…”

“…The first proposed antenna was also simulated with the commercial 3D EM finite element (FEM) solver at the Ansys HFSS 17.2 solver [15] for comparison and to diminish the high price of empirical evaluation [12], [13]. At the Ansys HFSS software, the adaptive mesh at auto mode was defined with the peak number of passes of 30 and peak delta S of 0.02, while the solution options were defined as first order with direct solver, and the frequency sweep type was defined as fast, and the virtual radiation boundary with vacuum was chosen to at least 𝜆 0 4 ⁄ away from the antenna.…”

There is still no high-directivity microstrip antenna with directivity beyond 25 dBi, bandwidth (BW) of more than 24%, which can be used for 6G cellular communication at low-THz at a resonance frequency of 144 GHz. So, duo broadband microstrip antennas have been designed at a resonance frequency of 144 GHz with the Taconic TLY-5 laminate in this work. These designs were carried out with the computer simulation technology microwave studio (CST MWS) software. The first antenna simulation results were compared within an Ansys high-frequency structure simulator (HFSS) software, and the obtained simulation results from both software were in fair consent, supporting the proposed designs. The peak directivity, peak gain, total peak efficiency, and BW obtained for the proposed THz microstrip antennas were 27.01 dBi, 25.3 dB, 78.96%, and 34.21 GHz (24.93%), respectively. Therefore, these antennas can be a base for 6G at low-THz.

“…A fractal antenna, with dimensions 800×600×81.29 μm 3 , provides a bandwidth of 9 THz (0.30 THz to 9.30 THz). This antenna consists of two slotted elliptical patches with a partial ground plane [12,14,19,20]. A single elliptical patch with a partial ground produces a THz bandwidth from 0.46 THz to 5.46 THz and a maximum gain of 12.0 dBi [16].…”

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).

“…Due to the short wavelengths of umWave, large capacity antennas can be designed. The reasons why the scienti c community is intensifying research in the development of antennas that can work effectively in the THz band [7][8][9][10][11][12][13][14][15]. In [7] a microstrip patch antenna for wireless communication at terahertz bands is presented.…”

For several years, the elds of new technologies have been experiencing a real boom. The use of the terahertz band is an appropriate solution to meet the requirements of these technology. However, this technology has special requirements among which its antennas must have high bandwidth of few THz and achieve high gain for high productivity. In this paper, we will focus on the design and analysis of an antenna for THz technology. The antenna structure proposed in this work has better performance in terms of bandwidth and gain. In fact, multiples slots were added to the antenna to enhance the antenna's bandwidth. in addition, to enhance the antenna performance in terms of gain and protect the antenna feed line against environmental jeopardies a thin layer as superstrate is used. The suggested antenna covers a wide − 10dB bandwidth from 0.9 THz to 17.3 THz with a peak gain of 12.8 dBi. Moreover, a VSWR less than 2 at the operating band is obtained. Furthermore, the suggested antenna has circular polarized radiations with an axial ration (AR) less than 3 dB over a wide band 13.6THz-17.3THz which mean that the proposed antenna is well suited for application where the transmitter and receiver are moving which is the most case for wireless system. Thus, the suggested THz antenna could be a successful choice for terahertz application like future high-speed short-range indoor wireless communication, explosive detections, arms detection, medical imaging, pharmaceutical analysis, and material characterization in the THz regime industrial inspections.
