“…Although the mmWave frequency band provides abundant bandwidth resources, compared with the traditional frequency band, the ordinary plane electromagnetic wave has a very high path loss in this frequency band, which seriously affects the system capacity [17][18][19][20][21]. In recent years, the information carrying ability of electromagnetic waves with orbital angular momentum (OAM) (also known as vortex electromagnetic waves) exhibited in the mmWave frequency band due to the vortex shape of the wavefront has attracted more and more attention [22][23][24][25]. The phase function of the OAM is e jlφ , where l is the number of topological charges, which is used to represent the OAM mode.…”

With the rapid growth in the number of mobile devices and user connectivity, the demand for higher system capacity and improved qualityof-service is required. As the demand for high-speed wireless communication grows, numerous modulation techniques in the frequency, temporal, and spatial domains, such as orthogonal frequency division multiplexing (OFDM), time division multiple access (TDMA), space division multiple access (SDMA), and multiple-input multiple-output (MIMO), are being developed. Along with those approaches, electromagnetic waves' orbital angular momentum (OAM) is attracting attention because it has the potential to boost the wireless communication capacity. Antenna electromagnetic radiation can be described by a sum of Eigen functions with unique eigenvalues, as is well known. In order to address such issues, the millimeter-wave (mmWave) communication is proposed which is considered as one of the potential technology for 5G wireless networks. The intrinsic feature of all electromagnetic waves is OAM. The OAM beams' unique qualities have led to a slew of new uses. Broadband OAM generators, on the other hand, have gotten very little attention, especially in the mmWave frequency band. The use of OAM in conjunction with mmWave can reduce the beam power loss, enhance the received signal quality, and hence increase the system capacity. The transmitter and receiver antennas must be coaxial and parallel to achieve precise mode detection. The proposed mmWave integrated with OAM system model is discussed in this study. The channel model is created using the channel transition characteristics. The simulation results demonstrate that the proposed system model is a good way to boost the system capacity.

“…People call this phenomenon the THz gap. The reason is that the technology used to generate and detect THz radiation is relatively immature, and there is still a lack of stable, efficient, and compact THz radiation sources under room temperature working conditions, especially 0.5 to 2.0 THz, an extremely important band in THz applications [1][2][3]. THz is located in the middle of the microwave and infrared bands in the electromagnetic spectrum, and has certain characteristics of microwave and light waves.…”

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.

“…The wavelength of millimeter wave is short, and the beam width of millimeter wave radar is narrow, so it has higher angular resolution and low-elevation tracking ability. The wider available frequency band of millimeter wave can improve the range resolution of the radar system, and the improvement of the range resolution can also improve the anti-jamming capability of the millimeter wave radar [1][2][3][4][5]. band communication, high path loss occurs between transmission and reception, unlike in the existing microwave band [15].…”

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.
