  ABSTRACT: Gold (Au) and ITO bow-tie antenna sensors built on silicon carbide (SiC) substrates are designed and analyzed using the Comsol Multiphysics program. The study shows that the output electric field across the antenna gap decreases with gap separation but increases with metal thickness. The antenna width does not directly affect the output, but it indirectly increases the output as a result of increased radiation absorption and conductivity. The length does not affect the strength of the output, but it affects the resonant frequency. The output field from ITO antennas is found to be much lower than that from Au antennas, which can be attributed, in part, to the lower conductivity of ITO. Using the bow-tie antenna structure, it is possible to build either narrowband or wideband antenna or sensor arrays, for THz applications.
