“…It is the primary determinant of electromagnetic wave absorption by human tissues. Several THz antennas have been designed for WBAN, but they are based on partial ground DGS [4][5][6][7][8][9][10][11][12][13], which are not suitable for WBAN applications because the human body influences them. Furthermore, these designs anticipate high back radiation, which is expected to be hazardous to one's health.…”

“…This investigation has resulted in efforts to integrate THz technology into wireless communication systems. Various antenna designs have been investigated to incorporate THz technology into wireless communication systems [1][2][3][4][5][6][7][8][9][10][11][12][13]. Among the antenna designs studied, microstrip planar antennas were discovered to be a very suitable candidate when compared to other designs with complex or three-dimensional designs [11,[14][15][16].…”

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.

“…In this structure, the radiating patch plane is assembled on one side of the dielectric substrate plane and the ground plane is on the other side. Some designed antenna structures are summarized in Table 1 (shown in the supporting information) [30][31][32][33][34][35]. In terms of the fabricated size of the microstrip antenna, there is a close relationship among the size of antenna, the resonant frequency, and the wavelength of THz wave: the total length of antenna is in inverse proportion to the resonant frequency and directly proportional to the wavelength.…”

Increasing demands for high-speed wireless communication have stimulated the development of novel optoelectrical devices. Typically, terahertz (THz) wave, is much advantageous because of its relatively high-resolution transportation and strong penetrability property. One of the electromagnetic devices, the antenna, plays a key role in future THz devices. However, there are few review publishments related to carbon-based THz microstrip antenna designs. In this article, we list the basic figure of merits for evaluating antennas. We also show the developing microstrip antenna structures. Importantly, we summarize the current progress of THz microstrip antennas using different dimensional carbon materials, such as carbon nanotubes, graphene, and carbon foams. This review will lay a solid foundation for carbon-based THz microstrip antenna design, and furthermore provide novel sights for other THz antenna designs.
