What is Antenna

A crucial technology to meet the growing demand for faster wireless communication is terahertz band (0.1–10 THz) communication. New generations of technology, such as 5G and 6G telecommunications, which have faster transmission speeds, larger network capacities, and shorter delays, will find extensive use soon. Due to fabrication and installation restrictions, particularly for smaller sizes, conventional telecommunications devices cannot support the new frequency. Two-dimensional materials have been proposed as the most suitable possibility to design and implement wireless telecommunications devices that meet these requirements. This chapter describes the advances made in the design of antennas, resonators, and electromagnetic interference shielding systems based on graphene and MXenes. Despite the advances achieved so far, future research directions required to commercialize the developed test-stage devices are also described. These materials must be investigated in this century to guarantee the success of 5G and 6G communications.
