Carbon-Based THz Microstrip Antenna Design: A Review

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.
