Terahertz conical dielectric resonator antennas (DRAs) have been designed, simulated and analyzed at a terahertz spectrum, i.e. 10 THz. A lower terahertz frequency band is useful for high data speed communication, whereas a terahertz frequency upper band is used for optical sensors or sensing applications. The free-space wireless communications also use terahertz DRAs (TDRAs). A unique and novel geometry for terahertz dual-band operations has been investigated with mathematical formulations. The comprehensive analyses in a terahertz regime have been worked out with a reflection coefficient (S ₁₁), a voltage standing wave ratio, a radiation pattern and efficiency using a conical TDRA. The conical TDRA is designed at 10 THz frequency with 4.9 dBi, gain and bore sight radiation pattern. The equivalent circuit of conical TDRA has been developed at given frequencies.
