“…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].…”

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.

“…As shown in Figure 13c, an FSS is a dense, metasurface-like configuration with resonant passive elements in an array, usually designed to intercept and interact with a bandwidth of interest [88]- [90]. These have traditionally been utilized to reduce the crosssection of radars [88], and recently have been proposed to reduce unwanted SLLs and leakage in wide-band antenna arrays above 100 GHz [91]. In addition, these have been proposed to reduce mutual coupling effects between antenna elements in densely packed antenna arrays [92].…”

The electromagnetic spectrum plays a fundamental role for the development of the digital society. It enables wireless communications (either between humans or machines) and sensing (for example for Earth exploration, radio astronomy, imaging, and radars, among others). While each of these uses benefits from a larger bandwidth, the spectrum is a finite resource. This introduces competing interests among the different stakeholders of the spectrum, which have led-so far-to rigid policies and spectrum allocations. Recently, the spectrum crunch in the sub-6 GHz bands has prompted communication technologies to move to higher carrier frequencies, where future 6G wireless networks can exploit theoretically very large bandwidths. However, the spectrum above 100 GHz features several narrow, yet numerous sub-bands that are exclusively allocated for passive sensing applications, e.g., for climate and weather monitoring. This prevents the allocation of large contiguous bands to active users of the spectrum, either being communications (which need tens of gigahertz of bandwidth to target terabit-per-second links) or radars. This paper explores how spectrum policy and spectrum technologies can evolve to enable sharing among different stakeholders in the above 100 GHz spectrum, without introducing harmful interference or disrupting either security applications or fundamental science exploration. This portion of the spectrum presents new opportunities to design spectrum sharing schemes, based on novel antenna designs, directional ultra-highrate communications, and active/passive user coordination. The paper provides a tutorial on current regulations above 100 GHz, and highlights how sharing is central to allowing each stakeholder to make the most out of this spectrum. It then defines-through detailed simulations based on standard International Telecommunications Union (ITU) channel and antenna models-scenarios in which active users may introduce harmful interference to passive sensing. Based on this evaluation, it reviews a number of promising techniques that can enable active/passive sharing above 100 GHz. The critical review and tutorial on policy and technologies of this paper have the potential to kickstart future research and regulations that promote safe coexistence between active and passive users above 100 GHz, further benefiting the development of digital technologies and scientific exploration.

“…There are several techniques are used to increase the gain and directivity of an antenna such as using an antenna array [15][16][17][18], adding an artificial magnetic conductor (AMC) below the antenna [19][20][21][22], and using the FSS. These techniques can be used to improve the antenna gain in microwave and mm-wave [23][24][25][26][27]. In [15], a 28 GHz four elements antenna array with hocked shape is investigated to increase the single antenna gain from 3.59 dBi to 10.3 dBi.…”

A millimeter-wave (mm-wave) antenna with enhanced gain for new 5G networks is introduced in this work. A rectangular slot antenna operating at the fundamental mode of the desired frequency band is utilized in this study. The antenna gain is improved by employing a Frequency Selective Surface (FSS). The FSS-based reflectors are designed at the same fundamental mode of the antenna and added under the antenna at a specific distance to achieve the required gain enhancement with a suitable dimension of 25 × 25 × 5 mm 3 . The antenna gain is increased by around 5.3 dBi when the FSS-based reflectors are added under the antenna. The antenna and the FSS are fabricated and tested. The antenna has tested outcomes without FSS with S 11 ≤ -10 dB from 26 GHz up to 29.8 GHz and realized gain of around 4.5 dBi within the entire frequency band and radiation efficiency of around 93 %. While the antenna with FSS has achieved bandwidth with S 11 ≤ -10 dB from 25.5 GHz up to 30.8 GHz and realized gain around 10.3 dBi at 28 GHz and radiation efficiency around 90 %. The simulated and tested outcomes have the same trend which validates the suggested antenna to be operated in the new 5G applications. All simulation results are completed using the CST Microwave Studio.
