As the world’s need for wireless communications grows at unprecedented rates, it is very crucial to continue developing technology that is able to accommodate high speed transmission and reception. As such, it is only natural for the shift from 5G communications to 6G communications to occur. Since 6G communications operate in the Terahertz frequency spectrum, the capability for controlling and exploiting terahertz waves, such as focusing, deflecting, and steering terahertz beams, is paramount to developing their application. In this project, the history of wireless communications, the necessity to upgrade the current framework of wireless communications as well as the theory that encapsulates all of it is discussed in great depth. At the end of it which, to gain a better practical understanding from all the theory, using CST simulation software, a waveguide integrated with a Dielectric Resonator Antenna (DRA) is modelled with specifications suited for Terahertz Frequency. Also, in the end, industrial knowledge of Vector Network Analyser (VNA) is discussed as means to test such Terahertz frequency components and assembly which are designed to cater to wireless communications.
