Terahertz cylindrical dielectric resonator antennas (DRAs) have been studied and implemented using computer simulation technology. The theoretically analyses have also been performed at terahertz frequency. Mathematical formulation for the Poynting vector and far fields radiated pattern for terahertz antennas have been developed. Their simulation results along with theoretical concepts have been presented. The work carried out in this chapter is much useful for high-speed communication applications and retinal artificial photoreceptors applications. This optical DRAs work can also be used for sensing, scanning, imaging and chip-to-chip communications. The cylindrical optical DRAs have been built at 521 THz with a gain of 4.04 dBi. Another optical DRA has also been developed at 10 THz with 6-dBi gain. Simulated results on both optical DRAs have been included in this chapter. Antenna parameters such as reflection coefficient (S ₁₁), radiation pattern, voltage standing wave ratio, impedance (Z11) plots along with other antenna results are included in this chapter. These are compact antennas and suitable for 5G and beyond networks for providing better connectivity with lower RF exposer levels.
