Abstract
The terahertz antenna has fantastic features of low ionization energy, high spectral efficiency, low damage, wide bandwidth, miniaturized, low profile, and most importantly ultra-high data rate in modern wireless communication systems. Through analysis and study of different materials, it is found that graphene has unique properties and provides a better solution for biomedical applications at terahertz region. Therefore, in this chapter are proposed graphene-based SISO THz antennas. A graphene-based circular patch SISO antenna is built on substrate of super compact size 21 × 21 × 2 μm3 and is analyzed for the material characteristics of Polyimide, Taconic RF-35TCA, Arlon AD 350A, Quartz, Rogers RO3035, and Silicon dioxide. A designed SISO THz antenna has single notch frequency around 6.4 THz for all different substrates. The 2D and 3D far field radiation patterns are significantly flared out from radiating elements, and have insignificant radiation below the THz antenna. These antennas have almost stable radiation patterns, and are similar to conventional microstrip patch antennas. The proposed THz SISO antenna has low penetration effect on the human body. Therefore, it is appropriate for wearable devices to monitor health conditions and foresee biological functioning of humans. The data can be processed to provide a real-time report to a medical health care unit.
