“…There are different types of photonic crystals such as 1D, 2D, or 3D structures, depending on their periodic arrangements. Two-dimensional (2D) photonic crystals have gained a lot of interest from many researchers in recent years, because they are much easier to fabricate compared to three-dimensional (3D) photonic crystals [43][44][45], furthermore, characterizing photonic crystal structures using a purely analytical approach is generally difficult because of their complexity. Therefore, fullwave simulators such as CST Microwave Studio, which is based on the finite integration technique have been used to analyze microstrip patch antennas designed based on photonic crystals substrate [46][47][48].…”

In this paper, a novel multiple input/multiple output (MIMO) antenna system with a graphene-based patch antenna arrays for THz communications channel capacity enhancement has been proposed and investigated. Systematic analysis has been conducted on the graphene load conductivity by determining the operating modes related to its chemical potential. Further, the projected MIMO antenna arrays have been designed with three different approaches such as homogeneous, photonic crystals and optimized photonic crystals. The targeted MIMO antenna arrays have been compared with their radiation characteristics such as return loss, bandwidth and gain. The obtained results in CST simulations of the proposed graphene-based 1×2 patch antenna array using optimized photonic crystals substrate exhibited excellent performance improvement as compared to the homogeneous substrate and photonic crystals substrate around 0.65 THz, which achieved a peak gain of 11.80 dB and broad bandwidth greater than 614 GHz. Next, The 2x2 MIMO system scenario was studied and analyzed using the mentioned targeted MIMO antenna arrays by calculating the total path loss and the channel capacity. The obtained results showed that the proposed 2x2 MIMO system with MIMO antenna array based on the optimized photonic crystals substrate achieved the highest capacity and the lowest total loss compared to a simple MIMO antenna array based on a homogeneous substrate. The capacity was calculated as 23.64 bit/s/Hz, and this was a remarkable enhancement compared with previously reported studies. In addition, this capacity was investigated further for different system configurations and different spacings between the transmission antennas and receiver antennas.

The frequency range of the terahertz (THz) band is usually defined as 0.3~3.0 THz, and some scholars have also extended it to 0.1~10 THz. THz technology has the characteristics of low photon radiation energy and rich spectrum information, and the THz band contains the vibration and rotation resonance frequencies of many material macromolecules, which can realize fingerprint detection. Therefore, THz technology has great academic value and a wide range of applications in basic research and applied science. Application prospects, such as THz spectroscopy technology provides a new means for studying the interaction between electromagnetic waves and matter, and its application in sensing has also penetrated into semiconductors, biology and medicine and health, homeland security, food quality control and environmental testing and other major fields. This paper proposes a novel patch antenna structure for the THz communication. The proposed antenna is designed on a polyimide substrate and graphene. The prominent feature of this antenna is that the radiation performance is does not deteriorates when tuning the frequency points. The frequency is controlled through a bias electrical field and not the conventional electronic switch. Theoretical analysis is performed for frequency-tuning and the equivalent circuit model is utilized to determine the input impedance. Simulation results show that the proposed THz antenna operates in the wideband THz with high gain and radiation efficiency.

Antennas have become a key component of millimeter wave development.…”

At present, the microwave frequency band bandwidth used for mobile communication is only 600 MHz. In 2020, the 5G mobile Communication required about 1 GHz of bandwidth, so people need to tap new spectrum resources to meet the development needs of mobile Internet traffic that will increase by 1,000 times in the next 10 years. Utilize the potentially large bandwidth (30∼300 GHz) of the millimeter wave frequency band to provide higher data rates is regarded as the potential development trend of the future wireless communication technology. A microstrip patch implementation approach based on electromagnetic coupling feeding is presented to increase the bandwidth of a dual-polarized millimeter-wave antenna. To extend the antenna unit's impedance bandwidth, coplanar parasitic patches and spatial parallel parasitic patches are used, and a 22 sub-array antenna is developed using paired inverse feed technology. The standing wave at the centre frequency of 37.5 GHz is less than 2 GHz. The antenna array's relative bandwidth is 6.13 percent, the isolation is >30 dB, the cross-polarization is −23.6 dB, and the gain is 11.5 dBi, according to the norm. The proposed dual-polarized microstrip antenna has the characteristics of wide frequency bandwidth, large port isolation, low cross-polarization, and high gain. The antenna performance meets the general engineering requirements of millimeter-wave dual-polarized antennas.
