Three-Dimensional Dirac Semimetal Antennas for Telecommunications in the Terahertz Spectrum

Utilizing the Terahertz (THz) spectrum is a way to decongest wireless communications by overcoming the demand for higher data transfer rate. Three-dimensional Dirac semimetals (3DS) are good materials to be used for THz devices due to their configurability and good response to the THz frequencies. We have designed and simulated the THz dipole antenna with Cadmium Arsenide as the antenna material. The resonance frequencies are obtained by both analytical calculations and observation of the maximum realized gain in the simulations. 3DS antennas may serve as a key technology to realizing high bandwidth wireless communication systems in anticipation of future 6G technologies.
