“…These characteristics have caught the interest of researchers working on wireless body area networks (WBAN) under this regime. WBAN is primarily used for health monitoring and consists of actuators and sensors placed beneath or on the human skin [39,40]. It can also be used in entertainment, sports, and other areas.…”

For future healthcare in the terahertz (THz) band, a triple-band microstrip planar antenna integrated with metamaterial (MTM) based on a polyimide substrate is presented. The frequencies of operation are 500, 600, and 880 GHz. The triple-band capability is accomplished by etching metamaterial on the patch without affecting the overall antenna size. Instead of a partial ground plane, a full ground plane is used as a buffer to shield the body from back radiation emitted by the antenna. The overall dimension of the proposed antenna is 484 × 484 μm 2 . The antenna's performance is investigated based on different crucial factors, and excellent results are demonstrated. The gain for the frequencies 500, 600, 880 GHz is 6.41, 6.77, 10.1 dB, respectively while the efficiency for the same frequencies is 90%, 95%, 96%, respectively. Further research has been conducted by mounting the presented antenna on a single phantom layer with varying dielectric constants. The results show that the design works equally well with and without the phantom model, in contrast to a partially ground antenna, whose performance is influenced by the presence of the phantom model. As a result, the presented antenna could be helpful for future healthcare applications in the THz band.

“…Recently, it has attracted much interest in various fields such as imaging, spectroscopy [2], 6G technology, radar, radio astronomy [3], airport security screening, explosive detection [4], and material analysis [5], because of its larger bandwidth, nonionizing properties, sensitivity to weak interactions, high data rate, high chemical selectivity, and high resolution in wireless communication [6]. The necessity for high gain antennas at THz frequencies is critical to counteract high path loss, and high atmospheric absorption at these frequencies, which will have a negative impact on the wireless link's budget [7]. Consequently, the challenge at hand is the requirement for an innovative antenna design that solves the particular difficulties presented by the THz frequency spectrum.…”

“…Some ways to design a THz antenna have been developed. Several publications on wireless communication in the THz frequency region have been published, including [7], where the authors presented a THz microstrip antenna for on body wireless body area network (WBAN) applications with a reflection coefficient of -52.4 dB, a gain of 11.9 dB, and a resonance frequency of 230 GHz. The drawback is that the recommended antenna is large, has a limited gain, and operates at a low frequency.…”

A slotted patch antenna operating at 118 GHz is proposed to address challenges in the terahertz (THz) frequency band for wireless communication systems. The antenna design, utilizing a Rogers RO3003 substrate, which has a dielectric constant of 3 and tan 0.001, strategically incorporates slots to enhance key performance parameters. Copper is employed for the ground and radiating patch, and a microstrip feeding method powers the antenna. High frequency structure simulator (HFSS) software is used for design and simulation, revealing resonance at 0.118 THz with a reflection coefficient of -42.41 dB and an impedance bandwidth of 4.42 GHz (115.84–120.26 GHz). At the operating frequency, the antenna exhibits a gain of 7.36 dB, maximum directivity of 7.38 dB, the voltage standing wave ratio (VSWR) of 1.01, and 99.75% radiation efficiency, all within a compact size of 1.5×1.3×0.1 mm³. The suggested antenna outperforms recent counterparts, making it suitable for applications like security screening and wireless communication systems (5G). Future efforts will target bandwidth expansion, gain enhancement, and further size reduction to enhance overall performance.

“…At the same time, mmWave wireless communication technology has the advantages of extremely wide bandwidth and easy miniaturization. In addition, the 60 GHz mmWave also has the advantage of not requiring authorization [9][10][11][12][13][14]. Therefore, the millimeter-wave wireless communication technology is expected to become one of the key technologies of 5G communication, especially suitable for high-speed, large-capacity communication [15,16].…”

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.
