Abstract

This paper presents the design of THz Vivaldi Antenna operating in the frequency band of 0.1-6 THz. An optimized design of the antenna is developed by using the CST software to realize an ultra-wideband impedance match, which ranges from 0.7 to 6 THz, as well as a high directivity level, which varies from 3.8 dBi at 2.5 THz to 7.8 dBi at 6 THz. The antenna gain Gmax is found to be -1.6 dBi at 5.5 THz its efficiency ηmax is 16.3 % at 5.25 THz, both of which are relatively low because of metallic and dielectric losses.
